[Matplotlib-users] function domain problems
Hi all, I'm having trouble plotting functions were the domain aren't the real numbers (R). Functions like x**-n, log(x), etc. Does anyone know if there's a simple way of solving this problem. Here's a little script and it's error: from pylab import * def f(x): return log(x) x = arange(-3, 4) plot(x, f(x)) show() Output: Traceback (most recent call last): File test, line 7, in ? plot(x, f(x)) File /usr/lib/python2.4/site-packages/matplotlib/pylab.py, line 2019, in plot ret = gca().plot(*args, **kwargs) File /usr/lib/python2.4/site-packages/matplotlib/axes.py, line 2111, in plot self.autoscale_view(scalex=scalex, scaley=scaley) File /usr/lib/python2.4/site-packages/matplotlib/axes.py, line 975, in autoscale_view if scaley: self.set_ylim(locator.autoscale()) File /usr/lib/python2.4/site-packages/matplotlib/ticker.py, line 839, in autoscale return take(self.bin_boundaries(dmin, dmax), [0,-1]) File /usr/lib/python2.4/site-packages/matplotlib/ticker.py, line 809, in bin_boundaries scale, offset = scale_range(vmin, vmax, nbins) File /usr/lib/python2.4/site-packages/matplotlib/ticker.py, line 783, in scale_range ex = divmod(math.log10(-meanv), 1)[0] OverflowError: math range error Thanks! - Using Tomcat but need to do more?

Re: [Matplotlib-users] Problem with windows install
I had the same problem today, and solved it by using matplotlib-0.87.2.win32-py2.4.exe On Wed, 2006-09-06 at 15:06 -0500, Ryan Krauss wrote: I am trying to install matplotlib on my office Windows computer.
