Graphing libraries for Qt? - Page 2

True, you'd have to jump through a couple of hoops to load compiled code from a zip file. Though if you did end up writing the plugin, I could be persuaded to include the component in calibre.

You're not. I've worked with matplotlib quite a lot the past year, and AFAIK, it depends on Numpy/Scipy in order to work. It's a great library if you already use those libraries, but I suspect it would be overkill to use in this case.

I used PyQt to develop a UI layer for one of my app, moneyGuru, and I ended up not using any graphing library at all and simply painted directly with QPainter. It's really not that complicated. All in all, for line graphs and bar graphs, it's about 300 lines. Surely not as much troubles as SIP/C++/cross compilation hell. The source is at https://bitbucket.org/hsoft/moneyguru

The parts that you'll find interesting are at https://bitbucket.org/hsoft/moneygur.../graph_view.py
