intersection on XY graph

[NikolaB]

Hi, 

how to find intersection on graph entering   two points???

  

[altenbach · Accepted solution]

Two points make a line and the intersection is where the difference between line and data is zero. You probably need to interpolate. Seems simple geometry...

If you have a model for the data, you can do a nonlinear fit, and operate on the analytical curve, of course..

(Why are you doing "path to string" followed by "string to path"? Seems circular. Your VI uses 100% CPU when it is not doing anything)

Of course in general there could be more than one intersection.
