Is there a good Python module for plotting Gantt Charts? I\'ve tried CairoPlot, but it produces buggy results for complex data sets and lacks many configuration options.
ChartDirector is pretty good at generating advanced charts of all kinds. It has decent python bindings, but it's, unfortunately, not native python or open source in general.
There are actually some Gantt chart examples/screenshots. The code also includes python demo's for building gantt charts.
If you're working on a web application, you can also consider Google Chart. It appears to be flexible/advanced enough for simple, Gantt-like charts. You can read more on this here, for example. Or just google for "google chart gantt"
