Parameters

  • x – (float or array_like) X coordinates.

  • y – (float or array_like) Y coordinates.

  • dx – (float) The length of arrow along x direction. Only valid when x is float.

  • dy – (float) The length of arrow along y direction. Only valid when y is float.

Arrow line graphic.

Example:

v = [-0.2, 0, .2, .4, .6, .8, 1, 1.2]
for i, overhang in enumerate(v):
    arrowline(.1,overhang,.6,0, headwidth=20,overhang=overhang)

xlim(0, 1)
ylim(-0.3, 1.3)
yticks(v)
xticks([])
ylabel('overhang')
antialias(True)
