Example: Using Polar Plots to Plot Data
1. Define the following data sets:
 force 1999 1620 1444 1365 1576 1510 1080 994 1412 1838 1350 967 1205 967 1350 1838 1412 994 1080 1510 1576 1365 1444 1620 range 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
2. Use an XY Plot to graph and visualize the data:
 The plot shows symmetry around the 13th data point.
3. Plot the same data using a polar plot:
 The symmetry is lost. You need to normalize the range so that the data is plotted over one cycle of the polar plot.
4. Convert the range (rng) to angles (angs) that are evenly spread over one cycle of the polar plot.

The angles are defined in radians. You can convert the radians to degrees by inserting the unit into the placeholder.
 angles angles deg
5. Plot the modified vectors:
6. To connect the last data point to the first, use the stack function to add the first data point to the end of the two data sets:
7. Plot the modified vectors:
Now the data set is plotted over one cycle and all the points are connected. Note that in PTC Mathcad, the angles are displayed in a counter clockwise fashion.
