You can write your own legend class...or subclass the plot and override the getLegendItems(...) method.

2. how can u create a stacked bar chart using xml?

Not exactly sure what you mean by that...but you can use the DatasetReader class to read a CategoryDataset from an XML file, then create a stacked bar chart from that.

I still don't understand...both the regular and stacked bar charts are created using a CategoryDataset. And you can use the DatasetReader class to read a CategoryDataset from an XML file. Whether you use that dataset for a bar chart or a stacked bar chart doesn't matter.
