Polar Plotting Problem - Mathcad 14 1

[Eleceng01]

I am trying to plot phasors (A-,B-,C-phase voltages) in Mathcad 14 on the same polar plot. When I try to add more than one voltage to the plot, it shows the symbol at the origin but will not plot it correctly. Anyone else run across this problem?

If you would post the *.mcd file it would help.

spc300, thanks for the reply. I was cleaning up the file to post (had to remove certain info) and I somehow fixed it?!

I will now have to troubleshoot this! Thanks again.

Ok , I have found the issue, but I can't figure out what is wrong - I have attached the MathCAD file now. Thanks again for the assistance.

When la is equal to 209, the radial scale defaults from 209 to 210, which unfortunately makes it appear that la is zero. Click once on the plot, the radial scales are on the right hand side. Change the lower value to 0 or some other value less than 209 and the plot will look correct.

That fixed it - Thanks pstuckey!!

(Now I am embarrassed of how easy it was)
