Polar Plot Display Options

Scale Options

  • 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 Show Levels in dB option is switched off, changing the dB Level Scale will switch it on.

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.
