Thanks, Being a novice, I am trying the first thing in the example gallery that caught my eye. Vlines does seem to be a better option. But what's puzzling me is why do I get just a plot of the axes with the following code? Where are the vertical lines that I am looking for?
from matplotlib import path from matplotlib import patches from matplotlib import pyplot as plt codes = (1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2, 1, 2) vertices = ((39525.540000000001, 144.91), (39525.540000000001, 161.352), (39874.5, 149.5), (39874.5, 166.142), (40205.0, 150.41), (40205.0, 167.05199999999999), (40518.449999999997, 149.36000000000001), (40518.449999999997, 166.00200000000001), (40828.0, 148.50999999999999), (40828.0, 165.15199999999999), (41173.239999999998, 151.16), (41173.239999999998, 167.602), (41510.0, 150.09), (41510.0, 166.732), (41858.0, 146.25), (41858.0, 162.892), (42158.0, 152.63999999999999), (42158.0, 169.28199999999998), (42486.889999999999, 155.22999999999999), (42486.889999999999, 171.672)) patch = patches.PathPatch(path.Path(vertices, codes)) plt.gca().add_patch(patch) plt.show() On Thu, 30 Oct 2008 Michael Droettboom wrote : >If your first tuple is "codes", and second is "vertices", > >You can do: > > from matplotlib import path > from matplotlib import patches > from matplotlib import pyplot as plt > >patch = patches.PathPatch(path.Path(vertices, codes)) >plt.gca().add_patch(patch) >plt.show() > > >However... rather than going through all that, have you >considered using vlines?
