A Line- and Bar-Chart would solve the majority of problems. I've installed PyQwt for PyQt4 and tried the examples, but only out of curiosity because I wasn't writing an application that needed those facilities at the time.

A Line- and Bar-Chart would solve the majority of problems. Veusz does line charts, and stepped charts (which are almost like bar charts...). It is implemented with PyQt4. You can use the windows.PlotWindow widget in your PyQt4 app, but unfortunately I haven't got round to documenting this properly... If you're interested I can give instructions.

Drawing charts in Qt
I would like to display some charts in a Qt application. But all the docs I find online are rather dusty and talk about Qt3. My application uses Qt4 however. I ran into PyQwt and matplotlib. But the docs of matplotlib are horrid and the example in their wiki covers Qt3, and things look quite cryptic to me. PyQwt looks much more interesting, but I have trouble installing it. On my machine it complains that sipconfig "has no attribute '_pkg_config'". In the end the application should also run on Windows boxes. And I suppose as long as I use the right versions and use the precompiled binaries, I should get it at least installed. But the thing with the version numbers looks like some major lottery game to me. If one of the elements in the chain (be it Qt, or Qwt) release new versions and the available binary distributions get "out of sync", future support for the written application becomes foggy. Has anyone ever successfully used these graphing libraries with PyQt? Or are there other graphing libraries available? In fact, my needs are modest. A Line- and Bar-Chart would solve the majority of problems. -- http://mail.python.org/mailman/listinfo/python-list
