matplotlib.patches.Arrow#

classmatplotlib.patches.Arrow(x,y,dx,dy,*,width=1.0,**kwargs)[source]#

Bases:Patch

An arrow patch.

Draws an arrow from (x,y) to (x +dx,y +dy).The width of the arrow is scaled bywidth.

Parameters:
xfloat

x coordinate of the arrow tail.

yfloat

y coordinate of the arrow tail.

dxfloat

Arrow length in the x direction.

dyfloat

Arrow length in the y direction.

widthfloat, default: 1

Scale factor for the width of the arrow. With a default value of 1,the tail width is 0.2 and head width is 0.6.

**kwargs

FancyArrow

Patch that allows independent control of the head and tail properties.

get_patch_transform()[source]#

Return theTransform instance mapping patch coordinatesto data coordinates.

For example, one may define a patch of a circle which represents aradius of 5 by providing coordinates for a unit circle, and atransform which scales the coordinates (the patch coordinate) by 5.

get_path()[source]#

Return the path of this patch.
