Issue with multiple polar plots

[elset191]

I have a vi where I graph three plots using the Polar plot vi.  The problem is that one of the graphs gets messed up when I plot them all. 

You can see that the outermost circle doesn't look right.  However, when I probe after the individual plots they seem to be ok, except the last one. 

I've attached a much simplified VI.

Hi Tim,

Thanks for the post and I hope your well today.

I can confirm that I can repoduce the issue. 

I was wondering did you have the same issue using this example..

Take a look at a modified piece of the code that works as I suppose you intended it to.

What do you think is the change in code that makes the difference?

[elset191]

Both of those seem to not show the issue.

Clearly I prefer Cornisih's solution to the other.  I am not sure I'll be able to use it in the context of my full program though, because the third plot is always changing.  I'll see if I can adapt it though.  

Thanks guys.

Well, I determined that it's the grid that makes it messed up.  If I change the color from grey to transparent the graphs look fine. Still can't pinpoint the difference between cornish's and mine...

[elset191]

I found the difference between mine and Cornish's. The fact that the plot was much bigger changed where the grid lines were, and so they didn't overlap with the actual plot.  When I resized the plot to make it comparable to mine they overlapped again and I saw the same issue.

For the first graph you have to draw the grid and it works fine.  Then for any subsequent graph you can change the grid color to transparent so it doesn't redraw over the other plots.

I'm using LabView 2018 Version 18.0 (32-bit)

I found that in this version the Polar Plot with Point Options VI

It allows you to make your plot lines thicker so they're more visible when plotted on top of a gridline
