Select a set of points in a xy graph

To be able to do this, you need to have every point as a one plot, and then you can use the PlotImage.Front property node to follow the mouse to draw a ROI on the graph, and then find the plots-points that are within the ROI and change the Color of those plots.

It might be easier to use a Picture Control Plot to start with.

Hi MikaeIH and thank you very much.It's exactly my goal.

I will try your example and if I have a question, I will say you.

Thank you again.

No Worries, that's why we are here :-)
The property node that will let you know the Coordinate Offset is a property node that is "Secret", you can only select this if you put this into your LabVIEW.ini file.
SuperSecretPrivateSpecialStuff=True

If you don't want you use this property node, you can just use a constant value.
