Hi,

I have a line chart that iv created using jfreechart. The graph has six lines.when the graph comes up, there are no lines on it.This is delibrate. Iv also made six check boxes. The problem i have is that when the check boxes are checked, the lines are supposed to apear, each line corresponding to the boxes that has been checked. But the lines are'nt appearing when the boxes are checked. Please can someone help. Thank you for your help.

Post all *relevant* code. You definitely need to have implemented some sort of action listener for the check boxes to even begin making this work. Did you do that?
