hi guys! i'm tring to group labels in the category expression in a chart (or in a chart pro). in a chart where i display the first three weeks of two years (2010 and 2011 for example), i would like to write something like in the example below: 1 2 3 | 1 2 3 2010 2011 it's something like grouping values in a report, but i want to to this in a chart category. could anyone help me???? Thanks...

I need in my report one multi-axis line chart, but i can't find any example and so I think that plugin jasperreport Chart pro doesn't support multi-axis. Anyone say me if I say right?
