Yes, a statistical package has been in our sights for a while now. This will probably be in the form of a plugin for FactoryPMI that provides many statistical chart types.
Our development schedule is full for a while, so I’d look for something like this around the first quarter of 2007.
Note that some of these charts can be approximated or achieved using the existing charts. For example, a histogram is simply a bar chart that shows frequencies of items. Something like a “SELECT COUNT(*) FROM MyTable GROUP BY MyCategory” query would work well for this.
Also, you can implement any arbitrary statistical calculations you’d like in Jython, and then push your derived statistical dataset into a chart. Not the easiest of tasks, but it is possible.
