What version of maploltib are you using? Your data displayed with correct scale with my installation of matplotlib 0.98.5.2. By the way, you're chaning the axes limit of the wrong axes. "matplotlib.pyplot.axes()" create a new axes.
Use plt.xlim (or plt.ylim for y-limit), or use the method of the existing axes. -JJ On Thu, Feb 19, 2009 at 8:22 PM, Nash, Brent R <brent.r.n...@jpl.nasa.gov> wrote: > Hey everyone, > > I'm fairly new to matplotlib, but have read through tons of the > documentation today and have a decent understanding of it.
