Have been playing around with some Analysis chart extensions tonight

Result is very basic Profit Distribution Chart.

I need a way to do bin range for the histogram. PS also ignore the Axis labels as I’m playing around here

Mark: Can you please a SQChart wrapper around the JFreeChart Histogram Chart so SQ can do proper histogram charts? At the moment I’m using Line graph instead.
