Hi to All,
I would like to select/deselect (multiple) displayed points in a BubbleSeries, preferable with Click then Ctrl+Click. I suppose there will be 3 issues to solve:
Q1: How to catch the click then recognize what point is under the cursor? (what point was clicked)
Q2: How to change the point's appearance (say increase radius, by changing the binded data, any better idea?). Btw: Can I change the shape of an individual point, like from circle to square?
Q3: Maintain what is selected. (in a list.) (does any internal implementation for this?)
Thanks in advance
Hello Justin,
I am just checking if you require any further assistance on the matter.
Hi Yanko,
Thanks for your very detailed and clear answer, and especially for the sample.

I have an other issue to solve, and your SeriesMouseLeftButtonDown gave me an idea. However I stucked.
I have ScatterLineSeries. I would like to display a tooltip like thing with one value when the user points to the line (_anywhere_). No other visual effect is accepted.
So I thought I will handle the OnSeriesMouseEnter. It works. However the e.Item is empty (correct, I was not pointed on an exact element in the serie, just the line.
Now I must know somehow the X and Y value of the mouse position according this ScatterLineSeries X and Y axes and the current zoom and pan.
Unfortunatelly I can not figure out how to do this. (btw the I would like to display a tooltip like thing where the mouse cursor is, that the next task and I also have no idea, how this can be accomplished.
Could you give me some directions?
Thx in advance
