Hi, all, Well, I've hit a new problem with the log
> plotting issue. Try the following commands after
> 'ipython -pylab':
> x=arange(25)+1 semilogx(x,x**2) hold(False)
> semilogx(x,x**2)
> I get an apparently unbreakable chain of "Cannot take log
> of nonnegative value" messages for every following
> plot(), semilog(), or loglog() command until ipython is
> exited. None of close(1), clf(), or cla() helps clear
> the problem. Only creating a new figure with figure(2)
> and plotting to it seems to help.
rm -rf your build subdir and reinstall matplotlib 0.72.1 or CVS. The
error string you report doesn't exist in the current code base, and I
can't reproduce your error.
