I have posted a solution earlier here:

What you need to do after is to write the buffered image to a file.

You can add a domain marker (in this case an IntervalMarker) to the plot and specify the layer to "Layer.BACKGROUND". addDomainMarker(Marker marker, org.jfree.ui.Layer layer) http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/plot/XYPlot.html#addDomainMarker(org.jfree.chart.plot.Marker,%20o...

I think you can get the bounds of the selected area. So, clone the chart, place the clone in another frame, and set the upper/lowerbounds of the axes according to the selected area.

He was suggesting that you create your own set of colors for your chart. Then, assign one of these colors to each of the series of the plot. Since you know the color you assigned, you can create your own legend with a JPanel for example.

Sorry, I don't understand what you are asking.

If your ChartPanels are inside a JPanel (or other containers in Swing), then you can get a BufferedImage from it using this method: http://stackoverflow.com/questions/1349220/convert-jpanel-to-image You could also get a BufferedImage from the ChartPanel for each chart and join these images together ...

How did the calculation fail? Did it return a negative number?

You can set one axis to be zoomable and the other not zoomable with the setRangeZoomable and setDomainZoomable methods in ChartPanel: http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/ChartPanel.html#setRangeZoomable(boolean) http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/Char...

haha.... I thought you weren't using crosshairs... :D If you are using crosshair, then just set the the crosshair not to lock on data points for both domain and range and you will get the exact location of the point clicked. http://www.jfree.org/jfreechart/api/javadoc/org/jfree/chart/plot/XYPlot.htm...

Try setting the chart's padding and/or the plot's insets.

How did you get the nearest point?

If your domain axis is a DateAxis, then I think you could try setting a "TimeLine" for the axis.

It should be possible. First, try adding an additional MenuItem to the existing menu and add an ActionListener to this MenuItem. Note: The current popup menu can be accessed with the getPopupMenu() in ChartPanel class. Then, implement your method to change the colors. Finally, call this new method i...

I don't know whether you can have labels on crosshair, but I have a workaround for this. You could add a ChartProgressListener to your chart. In the method "chartProgress(ChartProgressEvent event)", set up code to add/remove annotations to/from the chart. Your chart would fire a ChartProgressEvent w...

You don't need a time series for this, just use DefaultCategoryDataset for your bar chart. Make sure you add values to the dataset in the order from Jan to Dec. It would be something like this: DefaultCategoryDataset dataset = new DefaultCategoryDataset(); dataset.addValue(1.0, "series 1", "Jan"); d...
