Hi,
Does anyone know how to get a MultiplePiePlot to work with a subclass of a PiePlot? I tried changing MultiplePiePlotDemo1 to get a RingPlot instead of a PiePlot and it threw a class cast exception

There isn't any useful info in the developer guide.

Thanks,
Tim

For info of anybody else who comes across this problem it is a pre java 1.4 issue which requires you to have run a virtual frame buffer on your box to make JFreeChart work.

If u supply this command line parameter you should be ok:

I don't actually use JCreator but as an IDE i think you should be able to do something similar to this: download the jfreechart zip file and extract that to a directory. That will give you the jar files you need. In JCreator start a new project and then probably go to its properties and find where i...

Hi,
What is the suggested way to implement an equivalent of MultiplePieChart for a subclass of PiePlot, e.g. RingPlot? Should I just extend MultiplePieChart and alter it as needed or is there a better way to do this?

Thanks,
Tim

Impatient i know, just wondered if you had any idea when you'd be making the next release of JFreeChart.

Thanks,
Tim

This is done by setting the legend label generator. Described in this post:

You will want to change the first argument to your needs.

Start of words are cut off in tables when using IE 6.0.2900.2180 XP SP2.

For example, looking at class AbstractXYItemLabelGenerator. Under Constructor Summary, only YItemLabelGenerator is visible, rest has been chopped off.

Same applies for Method Summaries. eg. createItemArray only shows mArray.

I'm using 1.0.0-pre-2 and i tried replicating your problem using the following but it works fine for me: plot.setLabelGenerator(new StandardPieSectionLabelGenerator ("{0} ({2})" , new DecimalFormat("0.0"),new DecimalFormat("0.0"))); This gives the Label on one line with spaces e.g. One (0.3) . Can u...

1) As far as i'm aware this isn't possible at the moment as it is a non-trivial task. You have to consider how you will shift and wrap the legend if, for example, one bar is so big that it will run into the space allocated to the legend. If you implement this i'm sure a lot of people will be very gr...

BarRenderer renderer = (BarRenderer) plot.getRenderer(); renderer.setItemLabelFont(new Font("Arial", Font.BOLD, 9)); renderer.setLabelGenerator(new StandardCategoryLabelGenerator( "{2}", new DecimalFormat("0.0") )); renderer.setItemMargin(0.0); renderer.setItemLabelsVisible(true); i think this is t...

have u tried 0 instead of 1 when setting the renderer?

Excellent! Those changes work perfectly. Thanks a lot David. I can now extend LegendTitle to my heart's delight.

Thanks for your response David. Here is a modified version of PieChartDemo1 provided with the latest release to demonstrate the problem I am seeing. If there is a better way that i should be setting the LegendTitle please let me know and I'll try that out. import java.awt.Font; import java.util.Arra...
