matplotlib.pyplot.quiver(*args, data=None, **kw)
[source]
Plot a 2-D field of arrows.
Call signatures:
quiver(U, V, **kw) quiver(U, V, C, **kw) quiver(X, Y, U, V, **kw) quiver(X, Y, U, V, C, **kw)
U and V are the arrow data, X and Y set the location of the arrows, and C sets the color of the arrows. These arguments may be 1-D or 2-D arrays or sequences.
If X and Y are absent, they will be generated as a uniform grid. If U and V are 2-D arrays and X and Y are 1-D, and if len(X)
and len(Y)
match the column and row dimensions of U, then X and Y will be expanded with numpy.meshgrid()
.
The default settings auto-scales the length of the arrows to a reasonable size. To change this behavior see the scale and scale_units kwargs.
The defaults give a slightly swept-back arrow; to make the head a triangle, make headaxislength the same as headlength. To make the arrow more pointed, reduce headwidth or increase headlength and headaxislength. To make the head smaller relative to the shaft, scale down all the head parameters. You will probably do best to leave minshaft alone.
linewidths and edgecolors can be used to customize the arrow outlines.
