How to change the labels in jasper report charts?

[daad.madhusudan]

I am working on a jasper report and I am generating a chart with the following data:

reason  count

A            10

B             27

C            45

D             35

 

Now instaed on displaying labels I want to change it like

For 1st retrived reason label will be "Reason 1" for second "Reason 2" and so on. These labeling will be independent of reason codes mentioned in the output data.

Is there any way to set these labels using customizers like reason[0] = "Reason 1", reason[1] = "Reason 2"?

Please help to solve this problem

Since the reason label is based on report data row retreival sequence, you can use $V{REPORT_COUNT} in chart series or categories expression to meet your requirement:

"Reason "+$V{REPORT_COUNT}
