[Matplotlib-users] converting data between axis [0, 1] and data coordinates [min data, max data]

Hello all, I believe it is an easy thing to do but I haven't figured out how to convert between coordinate systems using transData or transAxes.Here is the simple_plot.py import numpy import pylab x = numpy.arange(0.0, 1.0+0.01, 0.01) y = numpy.cos(2*2*numpy.pi*x) pylab.plot(x, y) Here I wa

[Matplotlib-users] sync x axes on top and bottom
