Different BarChart that the demo does not contains

[Fry]

hello forum!

Im looking for a little bit different Barchart. Well through the search i have found one topic which is familar to mine. This one:
http://www.jfree.org/phpBB2/viewtopic.p ... rchart+top

Well, now i know that the Typ is called StackedBarChart. I tryed to run the code but there is something wrong with junit. However, can anybody give me a little example how i have to set up the categoryset? I think the method createStackedBarChart in the Class ChartFactory is the right one.
I think i need an array to fill up the categoryDataset, didn't i?

One more question: In the developer guide, are there also demos which are not included in the demoapplication? So e.g. StackedBarChart?

Thx 4 help

The CategoryDataset in a stacked bar chart is no different to the dataset for a regular bar chart - only the presentation is different. So, for example, you could run the BarChartDemo1 included in the org.jfree.chart.demo.* package, and change it to a stacked bar chart by changing the 'ChartFactory.createBarChart()' call to 'ChartFactory.createStackedBarChart()'.

Yes, for some reason the stacked bar chart demos are not enabled in the current release, but they are included in the demo download as separate applications. In the next release, they will be incorporated in the SuperDemo app.
