What is a dynamic barchart?

I think it means the lengths of the bars get updated automatically whenever the underlying dataset is changed.

I've also got an application that needs this sort of functionality. Any suggestion would be very much appreciated. Thanks.

--> Does anyone have an example-source for such a "dynamic barchart"??

In my case, the dataset should be changed via JSliders (the sliders work, the'startdataset' works and I'm searching and searching the web but I can't find an Example Code that changes my dataset (Integers and Doubles should be changed)??)

--> I hope that anyone can help me, greetings from Salzburg

BarChartDemo10.java (source code included with the JFreeChart Developer Guide) updates a dataset dynamically. It uses the DefaultCategoryDataset class --- updating is a simple call to the setValue() method.
