Bar chart with different scales for each series

[prophecy]

Can you have a bar chart with different scales on the data, say for example series A ranges from 1-10 and series B ranges from 0-1000. But if a bar in series A were 9, it would be the same height of bar as a value of 900 in series B.

Possible?

Hi,

It is possible, to have a bar chart with different heights w.r.t particular category.

for ex: if i have series A height as 9 and series B height as 999 then we can show separately with their heights in a single bar chart.

From this i cant send any attachment.

It needs a trick - for two series, you would need to define two datasets both containing two series (four series in all). In the first dataset, series 2 contains all null values. In the second dataset, series 1 contains all null values. Then you create a second range axis in the normal way, and have to override the legend to hide the two null series. See DualAxisDemo5.java in the demos included with the JFreeChart Developer Guide.
