Get selected DataItem?

[kaupov]

I have ChartPanel with XYPlot. I need to get the selected DataItem to do something useful with it.
My problem is that:

Code: Select all

ChartEntity entity = event.getEntity();

wants that I select the item very PRECISELY and it gives NULL if I miss it even a little.

On the other hand the anchor moves always to the right place. How can I get the DataItem that is connected with the anchor,
The code:

Code: Select all

this.getComponentAt((int)this.getAnchor().getX(),(int)this.getAnchor().getY())

won't work and gives me only the ChartPanel itself.

Could you just make the plot item larger? Easier to select?
