QPlot: patch

patch Draw a polygonal patch in data space

Call signature:

patch(xx, yy)

Help text:

patch(xx, yy) draws a polygon with vertices at (xx,yy). The polygon is automatically closed (i.e., it is not necessary for xx[-1] to equal xx[0]).
The polygon is filled with the current brush.
xx and yy are given in data coordinates. See also area and garea.

import qplot as qp

import numpy as np

qp.figure('patch', 3, 3)

qp.brush('g')

xx = np.linspace(0, 2*np.pi, 7)

qp.patch(np.cos(xx), np.sin(xx))

qp.brush('r', .5)

qp.patch(np.sin(xx), np.cos(xx))
