publication quality plotting with less problems than with crappy commercial software? Hell, yeah! :)
This would be ok if there were more sources of information such as more mailing lists. Are there any mailing lists besides here? I sent a question to this mailing list July 22,2012 and it never got posted even by 7/29/2012. For a newcomer it really isn't that easy to pick up. A whole area that would be good to address is limits: maximum dimensions possible. Highest granularity of time. And so on.
There are no 4 star reviews.
