Hello all, I'm starting a new application, and I want to do it in C++. Previously, I've coded similar things in Python and pygtk, using matplotlib for the graphics. Now I want to create an application in C++ with a GUI that needs to display simple plots and hidden surface 3D plots and that runs on

I gave this a shot, and eps2eps seems not to have any effect on the bounding box. I've done some experiments where I reduce the bounding box by hand, which works really well - the only problem is I need a way to determine where the edge of my plot really is. In Basemap, there is a box draw

Seems like a reasonable fix to me. I don't think the "classic" toolbars get as much testing as the new ones, which is probably how this fell through the cracks. I have committed this in SVN r4991. Cheers, Mike Jeff Peery wrote: > Hello, > I just upgraded to the most recent version of matplotl

Can you describe how you are changing the locale? It could be that Qt is reverting it to your system value every time a new figure window is created. Maybe you could set it somehow "deeper", like in an environment variable. Cheers, Mike Stephane Raynaud wrote: > Hi, > > when I set the local

Well, I want a way that I can use some function or an option/parameter of a function to do that. The code I am using to plot is like this: x = range(0,len(data)); lines = plot(x, data); setp(lines, linewidth=0.5) axis('tight') grid(True); xlabel('sampling points'); ylabel('quantilized steps'); ti

[Matplotlib-users] how to change the aspect ratio of a plot

Hi guys, I am quite new to matplotlib. I wanna know how to change the aspect of my plot in my program. I don't wanna change it by toolbar coz there are thousands of data that I can't change them one by one by myself. Thanks, Forrest -- Forrest Sheng Bao Ph.D. student, Dept. of Computer Science
