Polar plots enable you to view polar data in a 2D plot. You can control the traces by editing the tick marks on the radial axis.
Initially, PTC Mathcad treats negative radii as a phase shift in angle. You can edit the lower limit of the radial-axis to extend the radial scale to negative values.

Working with Polar Plot Parts
You can edit and format polar plots as you do for XY plots. There are however a few differences:
• Axes—The location of the axes are fixed. For the angular axis, you can only edit the interval between the angular axis tick marks. The tick marks are displayed in degrees.
• Trace Type—You cannot change the trace type of a polar plot. You can, however, change the trace style of a polar plot.
• Polar Plot Region—When you resize a polar plot region, the aspect ratio of the plot is always kept constant.
• Axis Expressions—When entered, the data is evaluated in radians unless you add the degree operator to the data definition.
