How can I estimate points from a curve?

[summer]

In the attached 3D graph there are different amplitude values on the z axis. I would like to plot a graph with points, estimated from the present data, for every 0.05 microvolts.

I have modified your VI so it generates a spline interpolation with a selectable number of points for the voltage axis (did you mean 0.05micro- or 0.05 mV???) Just calculate how many points you want!

I have also cleaned up your diagram "slightly". You can get rid of all the shift registers, and use the autoindexing function instead. The diagram is much simpler and also easier to read. I also modified it so it only recalculates if any input has changed. It is much easier on the CPU.

The spline function glitches a bit because your x-values are not sorted and there is a duplicate (0.03).

I have done it in LV6.1, but saved as 6.0 so you should be able to read it. Did you upgrade to 6.02?

Let me know if you have questions.

Hi altenbach, thank you so much for your help and for the time spending on this magic vi. It is exactly what I need. I can use a computer upgraded to 6.02. It is possible that I will have some questions.
