We'll be uploading the docs to ggplot.readthedocs.org this week (will update w/ url). Aside from that the best resources are here:
- http://blog.yhathq.com/posts/aggregating-and-plotting-time-series-in-python.html
- http://blog.yhathq.com/posts/ggplot-for-python.html
- http://ggplot.yhathq.com/
The docs just got a major facelift. Still a work in progress but you can check them out here: http://ggplot.yhathq.com/
