An axes instance does not provide data-properties. They belong to the lines, that were already plotted in that axes. But the axes instance provides a list of all plotted lines (gca().lines). xdata = getp(gca().lines[0], 'xdata') # or the OOP-way # last line instance of the list of lines: line = gca().lines[-1] ydata = line.get_ydata() regards Matthias > P.S.: It seems that the link > > http://matplotlib.sourceforge.net/matplotlib.pyplot.html#-getp > > on > > http://matplotlib.sourceforge.net/ > > is broken.
