XYZ-Polar-Contour
Select at least one group of XYZ columns in the worksheet. When plotting a Polar theta(X)r(Y)Z graph, X represents the Angle (Units are in degrees), Y is the Radius and Z data control the contour. When plotting a Polar r(X)theta(Y)Z graph, X is the Radius and Y is the Angle (Units are in degrees) and Z data control the contour.
Select required data.
From the menu, choose Plot > Contour: Polar Contour r(X) theta(Y)/Polar Contour theta(X) r(Y) .
or
Click the Polar Contour r(X) theta(Y)/Polar Contour theta(X) r(Y) button on the 3D and Contour Graphs toolbar.
