How can I plot multiple curves using the polar plot?

[dwyerjo]

I am using the polar plot indicator to graph angular-referenced data.  I need to be able to plot several curves on the same display.  How do I do this using the polar plot indicator?

Since polar plot is a picture in LV, it is not as convenient to plot multi curves as Waveform Graph or XY Graph. I create a VI to show how to plot two curves in polar plot for your reference. I use Labview 7.1.

Thanks! That answered my question perfectly!

Thank you for you vi
i had the same problem and now i have a solution ! i would like to have different colors for each curve.

Do you mean you want to set your own colours?

If so you can modify the above vi to use an array of color box constants. From there you can pick the colours you would like

Very well
Now, i understand the vi and the polar plot picture principle

on a simular query, is it possible to change the backgroud colour of the polar plot as well?

Hi

give me time to reinstall LV on my computer. I uninstall it few weeks ago.

if i remember well, it is possible to modify the numbers on the scale.

I will inform you.

Use the following vi and play with Polar attributes.

You will find how to change the values you need.
