I would like to use a XYBlockchart with the following features:
1. Highlight square when mouse is over it
2. Show tooltip (which is simple, as far as I know - just setting a flag == true)
3. Open an additional frame with a graph by double-clicking on a square
So the questions are:
Is highlighting possible at all (without too much effort)?
How do I get the the closest data point to the position I am clicking onto?
I would appreciate any help.
