PolarLineThreshold

Scope	Pepso
Type	Double
Default	0
.NET	PeGrid.Configure.PolarLineThreshold
Ocx\|Vcl	PolarLineThreshold
DLL	PEP_fPOLARLINETHRESHOLD

Purpose

This property manually sets how far default degree grid lines extend from the outer rim of polar chart inward. The value defined is measured with respect to the magnitude axis (Y axis).

Comments

PeGrid.Configure.PolarLineThreshold members of Pepso.PeGrid.Configure

Use this property with PolarTickThreshold, and Polar30DegThreshold to create a custom grid. Also related are XAxisLongTicks, and YAxisLongTicks.

This property should be used along with ManualScaleControlY if the data set does not include 0 as the origin. The threshold will be offset by ManualMinY.

ManualXAxisTicknLine and ManualYAxisTicknLine may also be used to customize the grid.

See example 205 for more info.

OCX Example

Polar plot has data going through the 0 orgin.

We want 30 degree radial lines to stop at magnitude 5.

Other radial X axis lines to stop at magnitude 20,

and X Axis tick marks (if using long ticks) to stop at 40

5 is the radius along y axis for 30 degree radial lines.

PEPolar1.Polar30DegThreshold = 5

20 is stopping radius for major radial lines

PEPolar1.PolarLineThreshold = 20

40 is radius for minor radial tick lines if LongYaxisTick is used.

PEPolar1.PolarTickThreshold = 40
