It's impossible to debug your code when you don't provide all of it. But all you need to do is this: JPopupMenu popup = new JPopupMenu(); popup.add(new JMenuItem("New Thing")); chartPanel.setPopupMenu(popup); This will replace the built in popup menu, so you will need to put back in the Properties, ...

Do you mean, you want a BufferedImage instead of a JFreeChart? If so, then look at JFreeChart.createBufferedImage(int width, int height).

Thanks for your help; I was able to do what I wanted fairly easily, all I had to do was: renderer.setPlot(this.mychart.getXYPlot()); This allows the XYItemRenderer to setup its DrawingSupplier which is used in the lookup methods. Paint paint = renderer.getSeriesPaint(seriesIndex); if (paint == null)...

My program uses a JTable to customize the XYDatasets, Domain and Range ValueAxes, and XYItemRenderers that will be put into a new JFreeChart. It's essentially a "Create a JFreeChart Wizard". Before the chart is created I allow the user to modify the XYSeries, ValueAxes, and XYItemRenderer for the cu...

The built in chart editor is rather simple and doesn't provide this functionality at all. However, you can replace or extend the built in chart editor to add this functionality. The following code shows how to get and set a series color and shape. All that is left to implement is a user interface to...

The JFreeChart object has a few methods for creating a BufferedImage of itself. Here's the simplest method:

For others (and Google searchers) reference: The best solution I have is to dissect the chart and keep everything in temporary variables then rebuild a new chart.

Having your own copy of a ChartEditor that is independent of updates to the built in ChartEditor is the only downside to my approach (that I know of). However, now that the basic framework is down, you can get clever and start replacing the My stuff back to Default stuff. The only file you needed to...

JFreeChart has a built in chart editor that comes up when you right click on a chart and select Properties. The current chart editor is very basic, but you can replace it with your own. See my post here on how to create your own chart editor: http://www.jfree.org/phpBB2/viewtopic.php?p=74702#74702 I...

You shouldn't set the tooltip text on a ChartPanel. The method setToolTipText(String) comes from Java/Swing and is meant to set a static string for a component. The ChartPanel doesn't use this, as the tooltip in a chart is not static, the tooltip changes depending on where the mouse is. If you look ...

Elaborating of what skunk said, there are two constructors for a ChartPanel to control what shows in the right click menu. ChartPanel(JFreeChart chart, boolean properties, boolean save, boolean print, boolean zoom, boolean tooltips) and ChartPanel(JFreeChart chart, int width, int height, int minimum...

That's all that is left to do with my code, and unfortunately I don't know how to do that.

The ChartPanel has a ChartMouseListener interface that you can implement that provides feedback about mouse moves and mouse clicks. You can create your own ChartMouseListener that is called when the mouse moves or mouse clicks. It then gets the data point you care about, and you can do whatever you ...

I am respecting the 1 to 1 relationship that JFreeChart wants, and an enforcing at least one dataset, one domain, one range, and one renderer remain. It looks like, all I literally need to do is decrement the private dataset ObjectList size.
