return a dictionary mapping property name -> value
Decorator for Artist.draw method. Provides routines that run before and after the draw call. The before and after functions are useful for changing artist-dependant renderer attributes or making other setup function calls, such as starting and flushing a mixed-mode renderer.
Return the value of object’s property. property is an optional string for the property you want to return
Example usage:
getp(obj) # get all the object properties
getp(obj, 'linestyle') # get the linestyle property
obj is a Artist instance, e.g., Line2D or an instance of a Axes or matplotlib.text.Text. If the property is ‘somename’, this function returns
obj.get_somename()
getp() can be used to query all the gettable properties with getp(obj). Many properties have aliases for shorter typing, e.g. ‘lw’ is an alias for ‘linewidth’. In the output, aliases and full property names will be listed as:
property or alias = value
e.g.:
linewidth or lw = 2
Return the value of object’s property. property is an optional string for the property you want to return
Example usage:
getp(obj) # get all the object properties
getp(obj, 'linestyle') # get the linestyle property
obj is a Artist instance, e.g., Line2D or an instance of a Axes or matplotlib.text.Text. If the property is ‘somename’, this function returns
obj.get_somename()
getp() can be used to query all the gettable properties with getp(obj). Many properties have aliases for shorter typing, e.g. ‘lw’ is an alias for ‘linewidth’. In the output, aliases and full property names will be listed as:
property or alias = value
e.g.:
linewidth or lw = 2
Set a property on an artist object.
matplotlib supports the use of setp() (“set property”) and getp() to set and get object properties, as well as to do introspection on the object. For example, to set the linestyle of a line to be dashed, you can do:
>>> line, = plot([1,2,3])
>>> setp(line, linestyle='--')
If you want to know the valid types of arguments, you can provide the name of the property you want to set without a value:
>>> setp(line, 'linestyle')
linestyle: [ '-' | '--' | '-.' | ':' | 'steps' | 'None' ]
If you want to see all the properties that can be set, and their possible values, you can do:
>>> setp(line)
... long output listing omitted
setp() operates on a single instance or a list of instances. If you are in query mode introspecting the possible values, only the first instance in the sequence is used. When actually setting values, all the instances will be set. e.g., suppose you have a list of two lines, the following will make both lines thicker and red:
>>> x = arange(0,1.0,0.01)
>>> y1 = sin(2*pi*x)
>>> y2 = sin(4*pi*x)
>>> lines = plot(x, y1, x, y2)
>>> setp(lines, linewidth=2, color='r')
setp() works with the MATLAB style string/value pairs or with python kwargs. For example, the following are equivalent:
>>> setp(lines, 'linewidth', 2, 'color', 'r') # MATLAB style
>>> setp(lines, linewidth=2, color='r') # python style
This module contains all the 2D line class which can draw with a variety of line styles, markers and colors.
Bases: matplotlib.artist.Artist
A line - the line can have both a solid linestyle connecting all the vertices, and a marker at each vertex. Additionally, the drawing of the solid line is influenced by the drawstyle, eg one can create “stepped” lines in various styles.
Create a Line2D instance with x and y data in sequences xdata, ydata.

See set_linestyle() for a decription of the line styles, set_marker() for a description of the markers, and set_drawstyle() for a description of the draw styles.
Test whether the mouse event occurred on the line. The pick radius determines the precision of the location test (usually within five points of the value). Use get_pickradius() or set_pickradius() to view or modify it.
Returns True if any values are within the radius along with {'ind': pointlist}, where pointlist is the set of points within the radius.

Manage the callbacks to maintain a list of selected vertices for matplotlib.lines.Line2D. Derived classes should override process_selected() to do something with the picks.
Here is an example which highlights the selected verts with red circles:
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.lines as lines
class HighlightSelected(lines.VertexSelector):
def __init__(self, line, fmt='ro', **kwargs):
lines.VertexSelector.__init__(self, line)
self.markers, = self.axes.plot([], [], fmt, **kwargs)
def process_selected(self, ind, xs, ys):
self.markers.set_data(xs, ys)
self.canvas.draw()
fig = plt.figure()
ax = fig.add_subplot(111)
x, y = np.random.rand(2, 30)
line, = ax.plot(x, y, 'bs-', picker=5)
selector = HighlightSelected(line)
plt.show()
Initialize the class with a matplotlib.lines.Line2D instance. The line should already be added to some matplotlib.axes.Axes instance and should have the picker property set.
When the line is picked, update the set of selected indicies.
Default “do nothing” implementation of the process_selected() method.
ind are the indices of the selected vertices. xs and ys are the coordinates of the selected vertices.
Determine if any line segments are within radius of a point. Returns the list of line segments that are within that radius.
Bases: matplotlib.patches.Ellipse
An elliptical arc. Because it performs various optimizations, it can not be filled.
The arc must be used in an Axes instance—it can not be added directly to a Figure—because it is optimized to only render the segments that are inside the axes bounding box with high resolution.
The following args are supported:

Ellipses are normally drawn using an approximation that uses eight cubic bezier splines. The error of this approximation is 1.89818e-6, according to this unverified source:
Lancaster, Don. Approximating a Circle or an Ellipse Using Four Bezier Cubic Splines.
There is a use case where very large ellipses must be drawn with very high accuracy, and it is too expensive to render the entire ellipse with enough segments (either splines or line segments). Therefore, in the case where either radius of the ellipse is large enough that the error of the spline approximation will be visible (greater than one pixel offset from the ideal), a different technique is used.
In that case, only the visible parts of the ellipse are drawn, with each visible arc using a fixed number of spline segments (8). The algorithm proceeds as follows:
The points where the ellipse intersects the axes bounding box are located. (This is done be performing an inverse transformation on the axes bbox such that it is relative to the unit circle – this makes the intersection calculation much easier than doing rotated ellipse intersection directly).
This uses the “line intersecting a circle” algorithm from:
Vince, John. Geometry for Computer Graphics: Formulae, Examples & Proofs. London: Springer-Verlag, 2005.
The angles of each of the intersection points are calculated.
Proceeding counterclockwise starting in the positive x-direction, each of the visible arc-segments between the pairs of vertices are drawn using the bezier arc approximation technique implemented in matplotlib.path.Path.arc().

ArrowStyle is a container class which defines several arrowstyle classes, which is used to create an arrow path along a given path. These are mainly used with FancyArrowPatch.
A arrowstyle object can be either created as:
ArrowStyle.Fancy(head_length=.4, head_width=.4, tail_width=.4)
or:
ArrowStyle("Fancy", head_length=.4, head_width=.4, tail_width=.4)
or:
ArrowStyle("Fancy, head_length=.4, head_width=.4, tail_width=.4")
The following classes are defined
Class Name Attrs Curve - None CurveB -> head_length=0.4,head_width=0.2 BracketB -[ widthB=1.0,lengthB=0.2,angleB=None CurveFilledB -|> head_length=0.4,head_width=0.2 CurveA <- head_length=0.4,head_width=0.2 CurveAB <-> head_length=0.4,head_width=0.2 CurveFilledA <|- head_length=0.4,head_width=0.2 CurveFilledAB <|-|> head_length=0.4,head_width=0.2 BracketA ]- widthA=1.0,lengthA=0.2,angleA=None BracketAB ]-[ widthA=1.0,lengthA=0.2,angleA=None,widthB=1.0,lengthB=0.2,angleB=None Fancy fancy head_length=0.4,head_width=0.4,tail_width=0.4 Simple simple head_length=0.5,head_width=0.5,tail_width=0.2 Wedge wedge tail_width=0.3,shrink_factor=0.5 BarAB |-| widthA=1.0,angleA=None,widthB=1.0,angleB=None
An instance of any arrow style class is an callable object, whose call signature is:
__call__(self, path, mutation_size, linewidth, aspect_ratio=1.)
and it returns a tuple of a Path instance and a boolean value. path is a Path instance along witch the arrow will be drawn. mutation_size and aspect_ratio has a same meaning as in BoxStyle. linewidth is a line width to be stroked. This is meant to be used to correct the location of the head so that it does not overshoot the destination point, but not all classes support it.

Classes for including text in a figure.
Bases: matplotlib.text.Text, matplotlib.text._AnnotationBase
A Text class to make annotating things in the figure, such as Figure, Axes, Rectangle, etc., easier.
Annotate the x, y point xy with text s at x, y location xytext. (If xytext = None, defaults to xy, and if textcoords = None, defaults to xycoords).
arrowprops, if not None, is a dictionary of line properties (see matplotlib.lines.Line2D) for the arrow that connects annotation to the point.
If the dictionary has a key arrowstyle, a FancyArrowPatch instance is created with the given dictionary and is drawn. Otherwise, a YAArow patch instance is created and drawn. Valid keys for YAArow are
| Key | Description |
|---|---|
| width | the width of the arrow in points |
| frac | the fraction of the arrow length occupied by the head |
| headwidth | the width of the base of the arrow head in points |
| shrink | oftentimes it is convenient to have the arrowtip and base a bit away from the text and point being annotated. If d is the distance between the text and annotated point, shrink will shorten the arrow so the tip and base are shink percent of the distance d away from the endpoints. ie, shrink=0.05 is 5% |
| ? | any key for matplotlib.patches.polygon |
Valid keys for FancyArrowPatch are
| Key | Description |
|---|---|
| arrowstyle | the arrow style |
| connectionstyle | the connection style |
| relpos | default is (0.5, 0.5) |
| patchA | default is bounding box of the text |
| patchB | default is None |
| shrinkA | default is 2 points |
| shrinkB | default is 2 points |
| mutation_scale | default is text size (in points) |
| mutation_aspect | default is 1. |
| ? | any key for matplotlib.patches.PathPatch |
xycoords and textcoords are strings that indicate the coordinates of xy and xytext.
| Property | Description |
|---|---|
| ‘figure points’ | points from the lower left corner of the figure |
| ‘figure pixels’ | pixels from the lower left corner of the figure |
| ‘figure fraction’ | 0,0 is lower left of figure and 1,1 is upper right |
| ‘axes points’ | points from lower left corner of axes |
| ‘axes pixels’ | pixels from lower left corner of axes |
| ‘axes fraction’ | 0,0 is lower left of axes and 1,1 is upper right |
| ‘data’ | use the coordinate system of the object being annotated (default) |
| ‘offset points’ | Specify an offset (in points) from the xy value |
| ‘polar’ | you can specify theta, r for the annotation, even in cartesian plots. Note that if you are using a polar axes, you do not need to specify polar for the coordinate system since that is the native “data” coordinate system. |
If a ‘points’ or ‘pixels’ option is specified, values will be added to the bottom-left and if negative, values will be subtracted from the top-right. e.g.:
# 10 points to the right of the left border of the axes and
# 5 points below the top border
xy=(10,-5), xycoords='axes points'
You may use an instance of Transform or Artist. See Annotating Axes for more details.
The annotation_clip attribute contols the visibility of the annotation when it goes outside the axes area. If True, the annotation will only be drawn when the xy is inside the axes. If False, the annotation will always be drawn regardless of its position. The default is None, which behave as True only if xycoords is”data”.

Bases: matplotlib.text.Text
This is basically a Text with a dash (drawn with a Line2D) before/after it. It is intended to be a drop-in replacement for Text, and should behave identically to it when dashlength = 0.0.
The dash always comes between the point specified by set_position() and the text. When a dash exists, the text alignment arguments (horizontalalignment, verticalalignment) are ignored.
dashlength is the length of the dash in canvas units. (default = 0.0).
dashdirection is one of 0 or 1, where 0 draws the dash after the text and 1 before. (default = 0).
dashrotation specifies the rotation of the dash, and should generally stay None. In this case get_dashrotation() returns get_rotation(). (I.e., the dash takes its rotation from the text’s rotation). Because the text center is projected onto the dash, major deviations in the rotation cause what may be considered visually unappealing results. (default = None)
dashpad is a padding length to add (or subtract) space between the text and the dash, in canvas units. (default = 3)
dashpush “pushes” the dash and text away from the point specified by set_position() by the amount in canvas units. (default = 0)
Note
The alignment of the two objects is based on the bounding box of the Text, as obtained by get_window_extent(). This, in turn, appears to depend on the font metrics as given by the rendering backend. Hence the quality of the “centering” of the label text with respect to the dash varies depending on the backend used.
Note
I’m not sure that I got the get_window_extent() right, or whether that’s sufficient for providing the object bounding box.
