Autoscale
Several sets of polar data may be displayed in the plot by loading them from appropriately formatted data
files.
Show Levels in dB
Display polar data on a dB scale, or not.
Level Scale
Tap on Level Scale to select a vertical scale for the plot in standard units per division.
Autoscale will be turned off. If the
Show Levels in dB option is switched on, changing the Level Scale will switch it off.
dB Level Scale
Tap on dB Level Scale to select a vertical scale for the plot in dB per division.
Autoscale will be turned off. If the

Plot Options
Orientation
The orientation of the plot can be set such that zero degrees is point up, or to the right.
Direction
The direction of increasing angles, from zero, can be set to clockwise (CW) or counterclockwise (CCW).
Angle Labels
Four sets of angle labels are available.
360: angles will be labeled increasing from 0 degrees all the way around the plot.
180: angles will be labeled increasing from 0 degrees half way around the plot and decreasing
in the opposite direction.
FBLR: 4 labels will be displayed, in locations depending on the orientation and direction
settings: Front, Back, Left, Right.
NSEW: 4 labels will be displayed, in locations depending on the orientation and direction
settings: North, South, East, West.
Grid Line Angles
Angular grid lines can be drawn in the plot at intervals of 15, 30, 45, or 90 degrees.
Grid Divisions
Circular grid lines can be drawn to establish a select number of circulat plot divisions between 1 and 10.
Cursor Options
Draw Cursor Circle
When a data cursor is drawn in the polar plot, a circle can be drawn with a radius corresponding to the selected
data point.
Cursor Data
If multiple sets of polar data are being plotted, the cursor circle can be set to follow any one of them.
The radius of the cursor circle, if enabled, will be associated with the selected polar data set.
