Thank you as that was extremely helpful! I had already created my own AbstractXYAnnotation class as I needed the pie chart to to be displayed in a relative position (similar to XYTitleAnnotation) near the corner, as opposed to a fixed location in data space. This is because I want the pie chart to a...

Thanks! I will give this a try.

In my program, my main chart is a CombinedDomainXYPlot which displays different sets of data. I also have a small pie chart which I'm adding to this x-y chart as an XYDrawableAnnotation. Everything works fine. However, I'm having trouble figuring out how/if I can implement tooltips for the individua...

Is there any way to create an annotation with a mouse-click event? Specifically, I'm using an XYTitleAnnotation and would like to call some code if the user clicks it.

I'm trying to create my own zoom rectangle where the user is not forced to always move the mouse to the bottom-right. Ideally, I'd like to create a zoom rectangle using any of the other three starting orientations (bottom-left, top-right, top-left). To do this, I have to change code in ChartPanel.ja...

Thanks. That makes sense.

I managed to "fix" the issue by changing all my "implements XYToolTipGenerator" classes to "extends StandardXYToolTipGenerator".

Clone fails in this self-contained code. There seems to be an issue with the XYToolTipGenerator. import org.jfree.chart.ChartFactory; import org.jfree.chart.JFreeChart; import org.jfree.chart.labels.XYToolTipGenerator; import org.jfree.chart.plot.XYPlot; import org.jfree.data.time.Month; import org....

Here is the stack trace. I'll try to get the code into a self-contained program. Exception in thread "AWT-EventQueue-0" java.lang.RuntimeException: java.lang.CloneNotSupportedException: Failed to clone. at org.jfree.chart.util.CloneUtils.cloneMapValues(CloneUtils.java:100) at org.jfree.chart.rendere...

I have been using the clone function with success until I updated to version 1.0.19. Now I get a CloneNotSupportedException. Here is my code: JFreeChart exportChart = null; try { exportChart = (JFreeChart) getChart().clone(); } catch (CloneNotSupportedException e) { logger.log(Level.SEVERE, null, e)...

In a Web Start application using JFreeChart, it's not possible for the user to "swap out" the JFreeChart JAR with their own version. Because of this, how does a Web Start application comply with the LGPL? If the Web Start application includes 1) "prominent" notice that the JFreeChart library is bein...

I'm using an XYLineAndShapeRenderer with shapes set to "hidden". My problem is that the tooltips are not being displayed when the mouse is hovering over these "hidden" shapes. If I set the shapes to visible in the renderer constructor, then the tooltips are correctly displayed when the mouse hovers ...

Thanks for the replies as I understand the problem. So there is no current way of detecting when the mouse passes over a line, if it doesn't also pass over where a point (shape) is?

I have implemented the ChartMouseListener for my ChartPanel. However, the method chartMouseEvent.getEntity() is not always returning an XYItemEntity. Sometimes the mouse cursor will be directly on top of a point in the line, yet getEntity() will return NULL. Here is my code: public void chartMouseMo...

Using the ChartUtilities.saveChartAsJPEG function in 1.0.9 seems to produce a JPEG with a transparent red background. Using the code in 1.0.8a produces a correct JPEG. Is this a bug? Here is my code: ChartUtilities.saveChartAsJPEG(file, chartPanel.getChart(), JPEG_WIDTH, JPEG_HEIGHT); 1.0.9 http://h...
