matplotlib.patches.YAArrow

class matplotlib.patches.YAArrow(figure, xytip, xybase, width=4, frac=0.1, headwidth=12, **kwargs)

Yet another arrow class.

This is an arrow that is defined in display space and has a tip at x1, y1 and a base at x2, y2.

Constructor arguments:

xytip

(x, y) location of arrow tip

xybase

(x, y) location the arrow base mid point

figure

The Figure instance (fig.dpi)

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
