27.12.2 Polar Graph


Polar graph.png

Data Requirements

Select at least one pair of XY columns. When using Polar theta(X) r(Y) to plot a graph, X represents the Angular (Units are in degrees) and Y is the Radius, and when using Polar r(X) theta(Y), X is the Radius and Y represents the Angular (Units are in degrees).

Creating the Graph

Take Polar theta(X) r(Y) for example.

  1. Select required data.
  2. From the menu, choose Plot > Specialized: Polar theta(X) r(Y)/Polar r(X) theta(Y).
or
Click the Polar theta(X) r(Y) button on the 2D Graphs toolbar.
