annotation Module#

Inheritance diagram of holoviews.plotting.mpl.annotation
class holoviews.plotting.mpl.annotation.ABLine2D(slope, intercept, *args, **kwargs)[source]#

Bases: Line2D

Draw a line based on its slope and y-intercept. Additional arguments are passed to the <matplotlib.lines.Line2D> constructor.

add_callback(func)#

Add a callback function that will be called whenever one of the .Artist’s properties changes.

Parameters#

funccallable

The callback function. It must have the signature:

def func(artist: Artist) -> Any

where artist is the calling .Artist. Return values may exist but are ignored.

Returns#

int

The observer id associated with the callback. This id can be used for removing the callback with .remove_callback later.

See Also#

remove_callback

property axes#

The ~.axes.Axes instance the artist resides in, or None.

contains(mouseevent)#

Test whether mouseevent occurred on the line.

An event is deemed to have occurred “on” the line if it is less than self.pickradius (default: 5 points) away from it. Use ~.Line2D.get_pickradius or ~.Line2D.set_pickradius to get or set the pick radius.

Parameters#

mouseevent : matplotlib.backend_bases.MouseEvent

Returns#

containsbool

Whether any values are within the radius.

detailsdict

A dictionary {'ind': pointlist}, where pointlist is a list of points of the line that are within the pickradius around the event position.

TODO: sort returned indices by distance

convert_xunits(x)#

Convert x using the unit type of the xaxis.

If the artist is not in contained in an Axes or if the xaxis does not have units, x itself is returned.

convert_yunits(y)#

Convert y using the unit type of the yaxis.

If the artist is not in contained in an Axes or if the yaxis does not have units, y itself is returned.

draw(renderer)#

Draw the Artist (and its children) using the given renderer.

This has no effect if the artist is not visible (.Artist.get_visible returns False).

Parameters#

renderer : .RendererBase subclass.

Notes#

This method is overridden in the Artist subclasses.

findobj(match=None, include_self=True)#

Find artist objects.

Recursively find all .Artist instances contained in the artist.

Parameters#

match

A filter criterion for the matches. This can be

  • None: Return all objects contained in artist.

  • A function with signature def match(artist: Artist) -> bool. The result will only contain artists for which the function returns True.

  • A class instance: e.g., .Line2D. The result will only contain artists of this class or its subclasses (isinstance check).

include_selfbool

Include self in the list to be checked for a match.

Returns#

list of .Artist

format_cursor_data(data)#

Return a string representation of data.

Note

This method is intended to be overridden by artist subclasses. As an end-user of Matplotlib you will most likely not call this method yourself.

The default implementation converts ints and floats and arrays of ints and floats into a comma-separated string enclosed in square brackets.

See Also#

get_cursor_data

get_aa()#

Alias for get_antialiased.

get_agg_filter()#

Return filter function to be used for agg filter.

get_alpha()#

Return the alpha value used for blending - not supported on all backends.

get_cursor_data(event)#

Return the cursor data for a given event.

Note

This method is intended to be overridden by artist subclasses. As an end-user of Matplotlib you will most likely not call this method yourself.

Cursor data can be used by Artists to provide additional context information for a given event. The default implementation just returns None.

Subclasses can override the method and return arbitrary data. However, when doing so, they must ensure that .format_cursor_data can convert the data to a string representation.

The only current use case is displaying the z-value of an .AxesImage in the status bar of a plot window, while moving the mouse.

Subclasses should override for inclusion in the bounding box “tight” calculation. Default is to return an empty bounding box at 0, 0.

Be careful when using this function, the results will not update if the artist window extent of the artist changes. The extent can change due to any changes in the transform stack, such as changing the axes limits, the figure size, or the canvas used (as is done when saving a figure). This can lead to unexpected behavior where interactive figures will look fine on the screen, but will save incorrectly.

See Also#

set_picker, get_picker, pick

property pickradius#

Return the pick radius used for containment tests.

See .contains for more details.

properties()#

Return a dictionary of all the properties of the artist.

remove()#

Remove the artist from the figure if possible.

The effect will not be visible until the figure is redrawn, e.g., with .FigureCanvasBase.draw_idle. Call ~.axes.Axes.relim to update the axes limits if desired.

Note: ~.axes.Axes.relim will not see collections even if the collection was added to the axes with autolim = True.

Note: there is no support for removing the artist’s legend entry.

remove_callback(oid)#

Remove a callback based on its observer id.

See Also#

add_callback

set(**kwargs)#

A property batch setter. Pass kwargs to set properties.

set_aa(b)#

Alias for set_antialiased.

set_agg_filter(filter_func)#

Set the alpha value used for blending - not supported on all backends.

Parameters#

alphascalar or None

alpha must be within the 0-1 range, inclusive.

set_animated(b)#

Set whether the artist is intended to be used in an animation.

If True, the artist is excluded from regular drawing of the figure. You have to call .Figure.draw_artist / .Axes.draw_artist explicitly on the artist. This appoach is used to speed up animations using blitting.

See also matplotlib.animation and /tutorials/advanced/blitting.

Parameters#

b : bool

set_antialiased(b)#

Set whether to use antialiased rendering.

Parameters#

b : bool

Alias for set_color.

set_clip_box(clipbox)#

Set the artist’s clip .Bbox.

Parameters#

clipbox : .Bbox

set_clip_on(b)#

Set whether the artist uses clipping.

When False artists will be visible outside of the axes which can lead to unexpected results.

Parameters#

b : bool

set_clip_path(path, transform=None)#

Set the artist’s clip path.

Parameters#

path.Patch or .Path or .TransformedPath or None

The clip path. If given a .Path, transform must be provided as well. If None, a previously set clip path is removed.

transform~matplotlib.transforms.Transform, optional

Only used if path is a .Path, in which case the given .Path is converted to a .TransformedPath using transform.

Notes#

For efficiency, if path is a .Rectangle this method will set the clipping box to the corresponding rectangle and set the clipping path to None.

For technical reasons (support of ~.Artist.set), a tuple (path, transform) is also accepted as a single positional parameter.

set_color(color)#

Set the color of the line.

Parameters#

color : color

set_contains(picker)#

[Deprecated] Define a custom contains test for the artist.

The provided callable replaces the default .contains method of the artist.

Parameters#

pickercallable

A custom picker function to evaluate if an event is within the artist. The function must have the signature:

def contains(artist: Artist, event: MouseEvent) -> bool, dict

that returns:

  • a bool indicating if the event is within the artist

  • a dict of additional information. The dict should at least return the same information as the default contains() implementation of the respective artist, but may provide additional information.

Notes#

Deprecated since version 3.3.

set_dash_capstyle(s)#

How to draw the end caps if the line is ~Line2D.is_dashed.

Parameters#

How to join segments of the line if it ~Line2D.is_dashed.

Parameters#

s : .JoinStyle or {‘miter’, ‘round’, ‘bevel’}

set_dashes(seq)#

Parameters#

seqsequence of floats (on/off ink in points) or (None, None)

If seq is empty or (None, None), the linestyle will be set to solid.

set_data(*args)#

Set the x and y data.

Parameters#

*args : (2, N) array or two 1D arrays

set_drawstyle(drawstyle)#

Set the drawstyle of the plot.

The drawstyle determines how the points are connected.

Parameters#

drawstyle{‘default’, ‘steps’, ‘steps-pre’, ‘steps-mid’, ‘steps-post’}, default: ‘default’

For ‘default’, the points are connected with straight lines.

The steps variants connect the points with step-like lines, i.e. horizontal lines with vertical steps. They differ in the location of the step:

  • ‘steps-pre’: The step is at the beginning of the line segment, i.e. the line will be at the y-value of point to the right.

  • ‘steps-mid’: The step is halfway between the points.

  • ‘steps-post: The step is at the end of the line segment, i.e. the line will be at the y-value of the point to the left.

  • ‘steps’ is equal to ‘steps-pre’ and is maintained for backward-compatibility.

For examples see /gallery/lines_bars_and_markers/step_demo.

set_label(s)#

Set a label that will be displayed in the legend.

Parameters#

sobject

s will be converted to a string by calling str.

set_linestyle(ls)#

ec : color

set_markeredgewidth(ew)#

Set the marker edge width in points.

Parameters#

ewfloat

Marker edge width, in points.

Parameters#

fc : color

set_markerfacecoloralt(fc)#

Set the alternate marker face color.

Parameters#

fc : color

set_markersize(sz)#

Set the marker size in points.

Parameters#

szfloat

Marker size, in points.

set_markevery(every)#

Set the markevery property to subsample the plot when using markers.

e.g., if every=5, every 5-th marker will be plotted.

Parameters#

everyNone or int or (int, int) or slice or list[int] or float or (float, float) or list[bool]

Which markers to plot.

  • every=None, every point will be plotted.

  • every=N, every N-th marker will be plotted starting with marker 0.

  • every=(start, N), every N-th marker, starting at point start, will be plotted.

  • every=slice(start, end, N), every N-th marker, starting at point start, up to but not including point end, will be plotted.

  • every=[i, j, m, n], only markers at points i, j, m, and n will be plotted.

  • every=[True, False, True], positions that are True will be plotted.

  • every=0.1, (i.e. a float) then markers will be spaced at approximately equal distances along the line; the distance along the line between markers is determined by multiplying the display-coordinate distance of the axes bounding-box diagonal by the value of every.

  • every=(0.5, 0.1) (i.e. a length-2 tuple of float), the same functionality as every=0.1 is exhibited but the first marker will be 0.5 multiplied by the display-coordinate-diagonal-distance along the line.

For examples see /gallery/lines_bars_and_markers/markevery_demo.

Notes#

Setting the markevery property will only show markers at actual data points. When using float arguments to set the markevery property on irregularly spaced data, the markers will likely not appear evenly spaced because the actual data points do not coincide with the theoretical spacing between markers.

When using a start offset to specify the first marker, the offset will be from the first data point which may be different from the first the visible data point if the plot is zoomed in.

If zooming in on a plot when using float arguments then the actual data points that have markers will change because the distance between markers is always determined from the display-coordinates axes-bounding-box-diagonal regardless of the actual axes data limits.

set_mec(ec)#

Alias for set_markeredgecolor.

set_mew(ew)#

Alias for set_markeredgewidth.

set_mfc(fc)#

Alias for set_markerfacecolor.

set_mfcalt(fc)#

Alias for set_markerfacecoloralt.

set_ms(sz)#

Alias for set_markersize.

set_path_effects(path_effects)#

Set the path effects.

Parameters#

path_effects : .AbstractPathEffect

set_picker(p)#

Sets the event picker details for the line.

Parameters#

pfloat or callable[[Artist, Event], tuple[bool, dict]]

If a float, it is used as the pick radius in points.

set_pickradius(d)#

Set the pick radius used for containment tests.

See .contains for more details.

Parameters#

dfloat

Pick radius, in points.

set_rasterized(rasterized)#

Force rasterized (bitmap) drawing for vector graphics output.

Rasterized drawing is not supported by all artists. If you try to enable this on an artist that does not support it, the command has no effect and a warning will be issued.

This setting is ignored for pixel-based output.

See also /gallery/misc/rasterization_demo.

Parameters#

rasterized : bool

set_sketch_params(scale=None, length=None, randomness=None)#

Set the sketch parameters.

Parameters#

scalefloat, optional

The amplitude of the wiggle perpendicular to the source line, in pixels. If scale is None, or not provided, no sketch filter will be provided.

lengthfloat, optional

The length of the wiggle along the line, in pixels (default 128.0)

randomnessfloat, optional

The scale factor by which the length is shrunken or expanded (default 16.0)

set_snap(snap)#

Set the snapping behavior.

Snapping aligns positions with the pixel grid, which results in clearer images. For example, if a black line of 1px width was defined at a position in between two pixels, the resulting image would contain the interpolated value of that line in the pixel grid, which would be a grey value on both adjacent pixel positions. In contrast, snapping will move the line to the nearest integer pixel value, so that the resulting image will really contain a 1px wide black line.

Snapping is currently only supported by the Agg and MacOSX backends.

Parameters#

snapbool or None

Possible values:

  • True: Snap vertices to the nearest pixel center.

  • False: Do not modify vertex positions.

  • None: (auto) If the path contains only rectilinear line segments, round to the nearest pixel center.

set_solid_capstyle(s)#

Parameters#

s : .CapStyle or {‘butt’, ‘projecting’, ‘round’}

How to join segments if the line is solid (not ~Line2D.is_dashed).

Parameters#

s : .JoinStyle or {‘miter’, ‘round’, ‘bevel’}

set_transform(t)#

Set the Transformation instance used by this artist.

Parameters#

t : matplotlib.transforms.Transform

set_url(url)#

Set the url for the artist.

Parameters#

url : str

set_visible(b)#

Set the artist’s visibility.

Parameters#

b : bool

set_xdata(x)#

Set the data array for x.

Parameters#

x : 1D array

Set the data array for y.

Parameters#

y : 1D array

set_zorder(level)#

Set the zorder for the artist. Artists with lower zorder values are drawn first.

Parameters#

level : float

property stale#

Whether the artist is ‘stale’ and needs to be re-drawn for the output to match the internal state of the artist.

property sticky_edges#

x and y sticky edge lists for autoscaling.

When performing autoscaling, if a data limit coincides with a value in the corresponding sticky_edges list, then no margin will be added–the view limit “sticks” to the edge. A typical use case is histograms, where one usually expects no margin on the bottom edge (0) of the histogram.

This attribute cannot be assigned to; however, the x and y lists can be modified in place as needed.

Examples#

>>> artist.sticky_edges.x[:] = (xmin, xmax)
>>> artist.sticky_edges.y[:] = (ymin, ymax)
update(props)#

Update this artist’s properties from the dict props.

Parameters#

props : dict

show_legend = param.Boolean(default=False, label=’Show legend’)

Whether to show legend for the plot.

anim(start=0, stop=None, fps=30)#

Method to return a matplotlib animation. The start and stop frames may be specified as well as the fps.

cleanup()#

Cleans up references to the plot on the attached Stream subscribers.

compute_ranges(obj, key, ranges)#

Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_aspect(xspan, yspan)#

Computes the aspect ratio of the plot

get_extents(element, ranges, range_type='combined', dimension=None, xdim=None, ydim=None, zdim=None)#

Gets the extents for the axes from the current Element. The globally computed ranges can optionally override the extents.

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

  • ‘data’: Just the data ranges

  • ‘extents’: Element.extents

  • ‘soft’: Dimension.soft_range values

  • ‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

  • ‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.

get_padding(obj, extents)#

Computes padding along the axes taking into account the plot aspect.

get_zorder(overlay, key, el)#

Computes the z-order of element in the NdOverlay taking into account possible batching of elements.

init_artists(ax, plot_args, plot_kwargs)#

Initializes the artist based on the plot method declared on the plot.

initialize_plot(*args, **kwargs)#

Initialize the matplotlib figure.

matches(spec)#

Matches a specification against the current Plot.

push()#

Pushes plot updates to the frontend.

refresh(**kwargs)#

Refreshes the plot by rerendering it and then pushing the updated data if the plot has an associated Comm.

set_root(root)#

Sets the root model on all subplots.

property state#

The plotting state that gets updated via the update method and used by the renderer to generate output.

teardown_handles()#

If no custom update_handles method is supplied this method is called to tear down any previous handles before replacing them.

traverse(fn=None, specs=None, full_breadth=True)#

Traverses any nested DimensionedPlot returning a list of all plots that match the specs. The specs should be supplied as a list of either Plot types or callables, which should return a boolean given the plot class.

update(key)#

Update the internal state of the Plot to represent the given key tuple (where integers represent frames). Returns this state.

update_frame(*args, **kwargs)#

Set the plot(s) to the given frame number. Operates by manipulating the matplotlib objects held in the self._handles dictionary.

If n is greater than the number of available frames, update using the last available frame.

update_handles(key, axis, annotation, ranges, style)[source]#

Update the elements of the plot.

cleanup()#

Cleans up references to the plot on the attached Stream subscribers.

compute_ranges(obj, key, ranges)#

Given an object, a specific key, and the normalization options, this method will find the specified normalization options on the appropriate OptionTree, group the elements according to the selected normalization option (i.e. either per frame or over the whole animation) and finally compute the dimension ranges in each group. The new set of ranges is returned.

get_aspect(xspan, yspan)#

Computes the aspect ratio of the plot

get_extents(element, ranges, range_type='combined', dimension=None, xdim=None, ydim=None, zdim=None)#

  • ‘data’: Just the data ranges

  • ‘extents’: Element.extents

  • ‘soft’: Dimension.soft_range values

  • ‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

padding = param.ClassSelector(class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=(0, 0.1), label=’Padding’)

Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.

padding = param.ClassSelector(class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=(0, 0.1), label=’Padding’)

Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.

aspect = param.Parameter(default=’square’, label=’Aspect’)

The aspect ratio mode of the plot. Allows setting an explicit aspect ratio as width/height as well as ‘square’ and ‘equal’ options.

color_index = param.ClassSelector(allow_None=True, class_=(<class ‘str’>, <class ‘int’>), label=’Color index’)

Index of the dimension from which the color will the drawn

class holoviews.plotting.mpl.chart.SpreadPlot(element, **params)[source]#

Bases: AreaPlot

SpreadPlot plots the Spread Element type.

Parameters inherited from:

holoviews.plotting.plot.DimensionedPlot: fontsize, fontscale, show_title, title, normalize

holoviews.plotting.mpl.plot.MPLPlot: projection, backend_opts, fig_alpha, fig_bounds, fig_inches, fig_latex, fig_rcparams, fig_size, initial_hooks, sublabel_format, sublabel_position, sublabel_size, show_frame

padding = param.ClassSelector(class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=(0, 0.1), label=’Padding’)

Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.

Dictionary to specify colors for clipped values, allows setting color for NaN values and for values above and below the min and max value. The min, max or NaN color may specify an RGB(A) color as a color hex string of the form #FFFFFF or #FFFFFFFF or a length 3 or length 4 tuple specifying values in the range 0-1 or a named HTML color.

cbar_padding = param.Number(default=0.01, inclusive_bounds=(True, True), label=’Cbar padding’)

Padding between colorbar and other plots.

padding = param.ClassSelector(class_=(<class ‘int’>, <class ‘float’>, <class ‘tuple’>), default=0, label=’Padding’)

Fraction by which to increase auto-ranged extents to make datapoints more visible around borders. To compute padding, the axis whose screen size is largest is chosen, and the range of that axis is increased by the specified fraction along each axis. Other axes are then padded ensuring that the amount of screen space devoted to padding is equal for all axes. If specified as a tuple, the int or float values in the tuple will be used for padding in each axis, in order (x,y or x,y,z). For example, for padding=0.2 on a 800x800-pixel plot, an x-axis with the range [0,10] will be padded by 20% to be [-1,11], while a y-axis with a range [0,1000] will be padded to be [-100,1100], which should make the padding be approximately the same number of pixels. But if the same plot is changed to have a height of only 200, the y-range will then be [-400,1400] so that the y-axis padding will still match that of the x-axis. It is also possible to declare non-equal padding value for the lower and upper bound of an axis by supplying nested tuples, e.g. padding=(0.1, (0, 0.1)) will pad the x-axis lower and upper bound as well as the y-axis upper bound by a fraction of 0.1 while the y-axis lower bound is not padded at all.

xticks = param.Parameter(default=20, label=’Xticks’)

Ticks along x-axis/segments specified as an integer, explicit list of ticks or function. If None, no ticks are shown.

yticks = param.Parameter(default=20, label=’Yticks’)

Ticks along y-axis/annulars specified as an integer, explicit list of ticks or function. If None, no ticks are shown.

clipping_colors = param.Dict(class_=<class ‘dict’>, default={‘NaN’: ‘white’}, label=’Clipping colors’)

Dictionary to specify colors for clipped values, allows setting color for NaN values and for values above and below the min and max value. The min, max or NaN color may specify an RGB(A) color as a color hex string of the form #FFFFFF or #FFFFFFFF or a length 3 or length 4 tuple specifying values in the range 0-1 or a named HTML color.

radial = param.Boolean(default=False, label=’Radial’)

Whether the HeatMap should be radial

show_values = param.Boolean(default=False, label=’Show values’)

The extents are computed by combining the data ranges, extents and dimension ranges. Each of these can be obtained individually by setting the range_type to one of:

  • ‘data’: Just the data ranges

  • ‘extents’: Element.extents

  • ‘soft’: Dimension.soft_range values

  • ‘hard’: Dimension.range values

To obtain the combined range, which includes range padding the default may be used:

  • ‘combined’: All the range types combined and padding applied

This allows Overlay plots to obtain each range and combine them appropriately for all the objects in the overlay.
