This command allows you to change the appearance of polar plots.


Right-click within an existing polar chart and select Polar Plot Options.

Angular units

Select the units for the independent variable. NOTE:  Changing units does NOT alter the input data in any way.

0 degrees at top of plot

By default, 0 degrees is drawn at the 3 oclock position.

Clockwise angles

If checked, angular values increase in a clockwise direction.

Force circular plots

If unchecked, then the plot will be drawn as large as possible, subject to the “Specify size” setting under Options>Extents/Intervals /Size.

If checked, the width and height of the plot are forced to be equal, which results in a circular plot. If the size has not been specified then it will be set to roughly 80% of the minimum of the document window width and height. You can override that size selection with the “Specify size” setting under Options>Extents/Intervals /Size.

Vertical radial axis labels

If checked, labels for the dependent variable will have a vertical orientation.

Center radial labels on the radius

If checked, labels for the dependent variable will be centered on the corresponding radius. If unchecked, labels will be left-justified (0 degrees at 3 oclock) or bottom-justified (0 degrees at top of plot).

Label 0 degrees

If unchecked, the 0 degrees label is not drawn, and the maximum radius label is drawn at or near that location. If checked, the 0 degrees label is drawn and the maximum radius label is not.

Axial grid lines start at

By default, axial grid lines emanate from the center of the plot. With a large number of grid lines (set with the Tick Marks settings under Options>Extents/Intervals /Size) and/or low resolution output, this may result in undesirable visual artifacts or a cluttered appearance.

Angles from 0 to +/- 180

Displays angular values as 0-180 and 360-angle for angles between 180 and 360 degrees.

Transform negative radii to angle+PI, abs(radius)

For negative radii, sets angle values to angle+180 degrees and radius=abs(radius). Note that unlike all other polar settings this option actually operates on the data and is therefore not reversible. The value added to the angle (X) coordinates is either 180 for angles in degrees or PI for angles in radians. Since this is a one-time operation it is important that you establish the correct angular units before using this option.
