Speed up plotting load-pull power contours

[altenbach]

You now have 25points/turn and an inward and outward spiral. If you only take the second half of the data and set the constant to 25points/turns, it already looks quite reasonable.

What I would do is interpolate all the data for a fixed angular increment, combine all points falling into a certain direction, and threshold into each spoke as above. Should not need major changes to what we already have. See how far you get.

Is it possible to implement that for me in the file you have already, as I did not understand the idea exactly. To be honest I am not that expert in LabVIEW.

The idea is geometric and has nothing to do with any programming language. That's why I showed all the extra graphs to demonstrate how the data looks like at the various stages.

Maybe I have time tonight to look at it again.

Really Appreciate your help

Hello, 

I wish if you had  a chance to look at the VI again. To be honest , I was keep trying to do what you mentioned in the last comment but I did not know how to do it exactly.

Appreciate your help

Ok I guess the Problem solved by decreasing the interpolation data. see the attached file .. there is an option to choose between the old and the new code

Sorry, I got side-tracked with other issues and did not have a chance to investigate further.

Still, this is clearly something that should be solved in polar coordinates (easiest by doing complex). Forcing simple, near circular data into a square grid just to extract circular data again later seems like a complete waste of computing resources.
