Variables in Chart

2003-11-29 10:42

I have ten variables in a report.

 

Steps at design time:

 

1. I create a parameter of type java.awt.Image and name it i.e. myChart

2. I add an Imageelement to the report and set the

image expression to $P{myChart} and type to java.awt.Image

 

 

How to include the values of the variables in chart?

Please note that a variable is different from a parameter. You are talking about parametrs.

 

To pass a parameter to the report you must use the HashMap passed to the method fillReport of jasperreports library. This HashMap contains a list of pairs name/value, where name is the parameter name in the report, and the value an object (in your case the chart image).
