Patch
(edgecolor=None, facecolor=None, color=None, linewidth=None, linestyle=None, antialiased=None, hatch=None, fill=True, capstyle=None, joinstyle=None, **kwargs)[source]¶
Bases: matplotlib.artist.Artist
A patch is a 2D artist with a face color and an edge color.
If any of edgecolor, facecolor, linewidth, or antialiased are None, they default to their rc params setting.
The following kwarg properties are supported
Property Descriptionagg_filter
a filter function, which takes a (m, n, 3) float array and a dpi value, and returns a (m, n, 3) array alpha

contains
(self, mouseevent, radius=None)[source]¶
Test whether the mouse event occurred in the patch.
Returns:contains_point
(self, point, radius=None)[source]¶
Returns True
if the given point is inside the path (transformed with its transform attribute).
radius allows the path to be made slightly larger or smaller.
contains_points
(self, points, radius=None)[source]¶
Returns a bool array which is True
if the (closed) path contains the corresponding point. (transformed with its transform attribute).
points must be Nx2 array. radius allows the path to be made slightly larger or smaller.
draw
(self, renderer)[source]¶
Draw the Patch
to the given renderer.
fill
¶
return whether fill is set
get_aa
(self)¶
Alias for get_antialiased
.
get_antialiased
(self)[source]¶
Returns True if the Patch
is to be drawn with antialiasing.
get_capstyle
(self)[source]¶
Return the current capstyle
get_data_transform
(self)[source]¶
Return the Transform
instance which maps data coordinates to physical coordinates.
get_ec
(self)¶
Alias for get_edgecolor
.
get_edgecolor
(self)[source]¶
Return the edge color of the Patch
.
get_facecolor
(self)[source]¶
Return the face color of the Patch
.
get_fc
(self)¶
Alias for get_facecolor
.
get_fill
(self)[source]¶
return whether fill is set
get_hatch
(self)[source]¶
Return the current hatching pattern
get_joinstyle
(self)[source]¶
Return the current joinstyle
get_linestyle
(self)[source]¶
Return the linestyle.
get_linewidth
(self)[source]¶
Return the line width in points.
get_ls
(self)¶
Alias for get_linestyle
.
get_lw
(self)¶
Alias for get_linewidth
.
get_patch_transform
(self)[source]¶
Return the Transform
instance which takes patch coordinates to data coordinates.
For example, one may define a patch of a circle which represents a radius of 5 by providing coordinates for a unit circle, and a transform which scales the coordinates (the patch coordinate) by 5.
get_path
(self)[source]¶
Return the path of this patch
get_verts
(self)[source]¶
Return a copy of the vertices used in this patch
If the patch contains Bezier curves, the curves will be interpolated by line segments. To access the curves as curves, use get_path()
.
get_window_extent
(self, renderer=None)[source]¶
Get the axes bounding box in display space.
The bounding box' width and height are nonnegative.
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.
set_aa
(self, aa)¶
Alias for set_antialiased
.
set_alpha
(self, alpha)[source]¶
Set the alpha transparency of the patch.
Parameters:set_antialiased
(self, aa)[source]¶
Set whether to use antialiased rendering.
Parameters:set_capstyle
(self, s)[source]¶
Set the patch capstyle
Parameters:set_color
(self, c)[source]¶
Set both the edgecolor and the facecolor.
set_ec
(self, color)¶
Alias for set_edgecolor
.
set_edgecolor
(self, color)[source]¶
Set the patch edge color.
Parameters:set_facecolor
(self, color)[source]¶
Set the patch face color.
Parameters:set_fc
(self, color)¶
Alias for set_facecolor
.
set_fill
(self, b)[source]¶
Set whether to fill the patch.
set_hatch
(self, hatch)[source]¶
Set the hatching pattern
hatch can be one of:
/ - diagonal hatching \ - back diagonal | - vertical - - horizontal + - crossed x - crossed diagonal o - small circle O - large circle . - dots * - stars
Letters can be combined, in which case all the specified hatchings are done. If same letter repeats, it increases the density of hatching of that pattern.
Hatching is supported in the PostScript, PDF, SVG and Agg backends only.
Parameters:set_joinstyle
(self, s)[source]¶
Set the patch joinstyle
Parameters:set_linestyle
(self, ls)[source]¶
Set the patch linestyle.
linestyle description'-'
or 'solid'
solid line '--'
or 'dashed'
dashed line '-.'
or 'dashdot'
dash-dotted line ':'
or 'dotted'
dotted line
Alternatively a dash tuple of the following form can be provided:
where onoffseq
is an even length tuple of on and off ink in points.
The line style.
set_linewidth
(self, w)[source]¶
Set the patch linewidth in points.
Parameters:set_ls
(self, ls)¶
Alias for set_linestyle
.
set_lw
(self, w)¶
Alias for set_linewidth
.
update_from
(self, other)[source]¶
Updates this Patch
from the properties of other.
