GetAltitudeColor Method (Heatmap3DLayer)

Calculates the blended iso-color in the spectrum appropriate for any Y-data value (altitude or temperature) on the surface.

Syntax

Visual Basic

'Declaration
 
Protected Function GetAltitudeColor( _
   ByVal startColor As Color, _
   ByVal endColor As Color, _
   ByVal val As Double _
) As Color

C#

protected Color GetAltitudeColor( 
   Color startColor,
   Color endColor,
   double val
)

Parameters

startColor

The starting color of the linear spectrum.

endColor

The ending color of the linear spectrum.

val

The altitude or temperature (Y data value).

Return Value

A blended color.

Remarks

The same blended iso-color is always returned for a given data value, as long as the Color Model has remained constant.

Blending is performed through linear interpolation equally across the Red, Green and Blue portions of the spectrum. It is not possible for the color returned to vary in fewer than all three primary colors unless the value of the primary color is identical in startColor and endColor.

Any opacity (or alpha) value in the supplied colors is ignored. Instead, the AlphaLevel of the chart's ColorAppearance is applied.
