Snap to closest graph point

[altenbach]

Do you want the closest point in terms of pixel distance or in terms of absolute distance. Since your x and y scales have very different scale, there will be a large difference between the methods.

I think pixel distance would suffice for my needs

try this...

Of course you still need to polish it up, for example you need to add an event for the stop button. Also the subVI code is a bit messy. 😉

Thanks very much for your help altenbach. Your knowledge holds no bounds

I know it's been like 8 years since this response, but I want to thank you for your incredible yet simple and elegant solution. I've been struggling with this problem for some years and I knew that I should use pixels to find the closest point, but I could never put together a solution.

Just threw off the window half of my code and pasted yours and worked like a charm.

Thank you, mr. Altenbach.
