LineAndShapeRenderer workout

Hello everybody

Is there any property/workout for a LineAndShapeRenderer to display items belonging to the same category a bit shifted?
What I mean is that if for the underlying CategoryDataset, the RowKeys are identical, to display -though- the items a bit shifted on the Ox axis?

Below is an image that explains better what I want. In this image, there are 5 series, and for each series the items are the same on Ox... can they be shifted within a given range for the Ox axis?

This feature was introduced in JFreeChart 1.0.7 - call the setUseSeriesOffet(boolean) method in the LineAndShapeRenderer class.

Brilliant!

Thanks, David

, you made my day.

Can this offset be set somewhere or it has fixed values/formula to establish the shift values?

The position is calculated by the getCategorySeriesMiddle() method in the CategoryAxis class (so if you override that method you can control the offset yourself).
