Re: [Matplotlib-users] screen colors invert with matplotlib

[Dan K. <ka...@tx...>]

Do the demo apps come with the standard qt4/pyqt4 install?  I just used the
Fedora Core 8 package manager to install both of these packages.

I apologize that my knowledge of qt is limited.  I'll do some investigation
of qt4 / pyqt4 on my own before bothering the list further.

Thanks for the suggestion,

-Dan

I wonder if the problem exhibits itself in any other pyqt4 apps (such as 
the demo apps)...  In that case, I would take your question to the pyqt 
list.  Otherwise, we'll want to track down what specifically matplotlib 
is doing that causes this.

Cheers,
Mike
