Help text:
pmark(xx, yy) draws marks at the given location in paper space.
xx and yy are relative to the top-left of the panel, or to the position set by at. Positive is right and down.
If you draw right up to any edge of the panel, shrink may fail.
See also marker and mark.
Example:

import qplot as qp

import numpy as np

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

xx = [1, 2, 3]

yy = [3, .5, 1.5]

qp.brush('555')

qp.bars(xx, yy, .5)

mrks='+-x'

for k in range(3):

        qp.at(xx[k], yy[k])

        qp.marker(mrks[k])

        qp.pmark(0,-10)
