When we initially designed and implemented BarChart, the idea was that it is a Chart that shows rectangular ( horizontal or vertical) bars representing some value for a given category. That is how many charting packages depict BarCharts including JfreeChart etc. Also, for simple cases, one can plot date as categories. Jasper was our original Charts designer/implementer, so correct me if I am wrong Jasper. However, for what you would like to plot - two value axes based BarChart - would IMHO be a CustomBarChart - another subclass of XYChart. I think JFreeChart calls it a XYBarChart, if I am right. Sorry, we do not have one such implementation at this point.

Hi, BarChart only allows you to insert a ValueAxis/CategoryAxis combination. So you can't have a ValueAxis/ValueAxis or it will throw a runtime exception. I don't understand this limitation, I'm creating a DateAxis and want to have a NumberAxis/DateAxis barchart. Can you tell me why this limitation exists? Best regards,
