I need to create LINE, BAR, and PIE diagrams in Rails. I have found several that do all this. However, one of the caveats is that I can never find a solution that does everything, as well as XY-SCATTER. I looked at Griff, Scruffy, Gnuplot, etc., And none of them are "all." Can anyone recommend a local library (i.e. does not require a network connection) that can accommodate? GoogleCharts is not an option, as some of them will appear on closed networks.
Best.
