Bounding regions and bounding boxes.

File originally part of the Topographica project.

class holoviews.core.boundingregion.AARectangle(*points)[source]#

Axis-aligned rectangle class.

Defines the smallest axis-aligned rectangle that encloses a set of points.

Methods

`bottom`()	Return the y-coordinate of the bottom of the rectangle.
`centroid`()	Return the centroid of the rectangle.
`lbrt`()	Return (left,bottom,right,top) as a tuple.
`left`()	Return the x-coordinate of the left side of the rectangle.
`right`()	Return the x-coordinate of the right side of the rectangle.
`top`()	Return the y-coordinate of the top of the rectangle.

Examples

>>> aar = AARectangle( (x1,y1),(x2,y2), ... , (xN,yN) )

right()[source]#: Return the x-coordinate of the right side of the rectangle.

class holoviews.core.boundingregion.BoundingBox(**args)[source]#

A rectangular bounding box defined either by two points forming an axis-aligned rectangle (or simply a radius for a square).

Methods

`contains`(x, y)	Returns true if the given point is contained within the bounding box, where all boundaries of the box are considered to be inclusive.
`contains_exclusive`(x, y)	Return True if the given point is contained within the bounding box, where the bottom and right boundaries are considered exclusive.
`containsbb_exclusive`(x)	Returns true if the given BoundingBox x is contained within the bounding box, where at least one of the boundaries of the box has to be exclusive.
`containsbb_inclusive`(x)	Returns true if the given BoundingBox x is contained within the bounding box, including cases of exact match.
`lbrt`()	Return left,bottom,right,top values for the BoundingBox.
`upperexclusive_contains`(x, y)	Returns true if the given point is contained within the bounding box, where the right and upper boundaries are exclusive, and the left and lower boundaries are inclusive.

contains(x, y)[source]#: Returns true if the given point is contained within the bounding box, where all boundaries of the box are considered to be inclusive.

contains_exclusive(x, y)[source]#: Return True if the given point is contained within the bounding box, where the bottom and right boundaries are considered exclusive.

containsbb_exclusive(x)[source]#: Returns true if the given BoundingBox x is contained within the bounding box, where at least one of the boundaries of the box has to be exclusive.

containsbb_inclusive(x)[source]#: Returns true if the given BoundingBox x is contained within the bounding box, including cases of exact match.

upperexclusive_contains(x, y)[source]#: Returns true if the given point is contained within the bounding box, where the right and upper boundaries are exclusive, and the left and lower boundaries are inclusive. Useful for tiling a plane into non-overlapping regions.

class holoviews.core.boundingregion.BoundingEllipse(**args)[source]#

Similar to BoundingBox, but the region is the ellipse inscribed within the rectangle.

Methods

Returns true if the given point is contained within the bounding box, where all boundaries of the box are considered to be inclusive.

contains(x, y)[source]#: Returns true if the given point is contained within the bounding box, where all boundaries of the box are considered to be inclusive.

class holoviews.core.boundingregion.BoundingRegion[source]#

Abstract bounding region class, for any portion of a 2D plane.

Only subclasses can be instantiated directly.

Methods

Return the coordinates of the center of this BoundingBox

centroid()[source]#: Return the coordinates of the center of this BoundingBox
