Multiple data series on one chart?

Post by rick » Wed Aug 22, 2001 8:10 pm

is it possible to have multiple data series on one chart. Each with its own graphical representation?

i.e.
series1 is a column chart
series2 is a line chart

Hi Rick,

It's not possible in version 0.5.6, but some work is being done towards making it available in the future. I need JFreeChart to support price/volume charts which will require a bar plot and a line plot sharing a common x-axis but each with their own y-axis.

The first step towards this goal is to implement a bar plot based on an extension of the existing XYDataSource. Once that is working, I'd like to improve the time series features in JFreeChart. Then finally change all the internals of JFreeChart so that you can add a second Plot to be overlayed with the existing one.

I only wish that I had more time to work on JFreeChart so I could get these things out quicker...

Regards,

DG.
