the first problem is that when you run the code below you’ll see that the chart (or jpanel1) seems to be duplicate in the background. The one in background disappear when you resize the frame. So first question is how to avoid having a second chart in the background?
When I click on the jbutton1 it removes jpanel1 from the frame. But when I want to re-add the panel, the panel remains blank. I tried to repaint() the chart with “chart.getCanvas().forceRepaint()” or “chart.render();”.
Im making an app with many forms. I would like to create a chart only one time and store it in a form (JPanel) in order to display it quickly at any time. How could I do that ? Thank you in advance for your response
