Multiplot polar chart?

[jeff_scharpf]

Does Labview provide a polar chart function and can it be used with multiple plots?

I am going to be measuring the runout of a shaft in 4 (simulataneous) locations using the cRIO if possible.

I have 4 linear gauge sensors that have quadature outputs. This is the reason I need the cRIO.

I will be turning a motor 360 degrees through serial commands and measuring the runout of a shaft from 4 locations.

I want to plot the result of this on a polar graph, preferrably with all plots on one graph for comparison.

Is this possible?

Any recommendations?

Regards,

Jeff

Hello

LabVIEW provides the VI "Polar Plot.vi". Add a polar plot from the the control palet, Graph, Element, Polar Plot Indicator. In the diagram appears a VI which draws one polar plot on an image. When you copy this VI and connect its output new picture to the input picture of the first VI, two plots are drawn on the same image. You must set the same maximum and minimum in polar attributes to receive only one grid. I add a simple example.

It might be easier to use the SubVIs of Polar Plot.vi.

I hope this helps, even if I do not understand all the technical details of your application.

Thanks shb!
I'm going to try this code as soon as I can get my serial port working lol.
