matplotlib.patches.ConnectionStyle

class matplotlib.patches.ConnectionStyle

ConnectionStyle is a container class which defines several connectionstyle classes, which is used to create a path between two points. These are mainly used with FancyArrowPatch.

A connectionstyle object can be either created as:

ConnectionStyle.Arc3(rad=0.2)

or:

ConnectionStyle("Arc3", rad=0.2)

or:

ConnectionStyle("Arc3, rad=0.2")

The following classes are defined

Class	Name	Attrs
Angle	angle	angleA=90,angleB=0,rad=0.0
Angle3	angle3	angleA=90,angleB=0
Arc	arc	angleA=0,angleB=0,armA=None,armB=None,rad=0.0
Arc3	arc3	rad=0.0
Bar	bar	armA=0.0,armB=0.0,fraction=0.3,angle=None

An instance of any connection style class is an callable object, whose call signature is:

__call__(self, posA, posB,
         patchA=None, patchB=None,
         shrinkA=2., shrinkB=2.)

and it returns a Path instance. posA and posB are tuples of x,y coordinates of the two points to be connected. patchA (or patchB) is given, the returned path is clipped so that it start (or end) from the boundary of the patch. The path is further shrunk by shrinkA (or shrinkB) which is given in points.

return the instance of the subclass with the given style name.
