Here is the class I wrote. It makes the assumption that the plot is an XYPlot of some form, but that can be worked around if necessary. It also invokes another utility class for checking if a plot is a combined plot and getting all subplots. You can either ignore that part, write your own, or get th...

I wrote a cewolf ChartPostProcessor to modify the color of the series in a chart rather than using the default ones. Changing the actual series colors was easy, but I don't see a quick way to get the legend to refresh the color boxes next to the LegendItems with the new colors. The LegendItems thems...

For anyone interested, I have posted a new version of these extensions along with a more complete example and docs. http://sourceforge.net/projects/meta-jb/ The charting stuff is in the Extras package. It's a single zip download. You will need the jars in the Core release as well (again, a single do...

No prob. Glad it was of use. If you want the latest version with some better calcs for when to draw labels and some more stuff, I just pushed it to the sourceforge patches tracker: http://sourceforge.net/tracker/index.php?func=detail&aid=1218160&group_id=15494&atid=315494 Javadoc of what it does: Ha...

Very nice! I have also done some work in this area. I posted a summary here a while back: http://www.jfree.org/phpBB2/viewtopic.php?t=12599 Dave's approach is straightforward and definately less intrusive. Mine is sort of a mini-charting-framework since it uses concepts from the meta-jb project othe...

All, I've written some extensions for reading in chart configurations from XML and feeding data into charts from a variety of objects without writing any new code to do so (again, configuration happens via XML). The extensions are a new package within the meta-jb project on source forge: http://sour...

Actually there are demos for the stacked bar charts. They just aren't shown in the main SuperDemo container. I just stumbled across them now (wish I had seen them yesterday ). StackedBarChart3DDemo and StackedBarChartDemo1 to StackedBarChartDemo4. You can run them standalone easily.

I actually pulled out the code to a temporary subclass so I don't have to custom build the jfreechart jars. Here is is. All but the last couple of lines are just copied from the parent class to get the proper coordinates. I use the .9.21 code base if that makes a difference to folks: public class St...

Funnny you should ask since I just had to do that this morning in StackedXYBarRenderer. If you mean the regular category StackedBarRenderer, I think that just turning on ItemLabelsVisible (see AbstractRenderer javadoc or look at the BarChartDemo3.java in the sample code for some good settings with t...

I have seen many posts for people asking for ways to get information from a mouse click when there isn't a ChartEntity directly under the click (like for a line on an XY line chart, for example). I had a similar need and came up with this mouse handler this morning. It finds the closest ChartEntity ...
