Properties

FirstLineName

Summary

The name of the first indicator line.

Signature 

1
public string FirstLineName {get;}

Return Value

string

SecondLineName

Summary

The name of the second indicator line.

Signature 

1
public string SecondLineName {get;}

Return Value

string

Opacity

Summary

The cloud opacity. Value can be set from 0 (transparent) to 1 (opaque). Values higher than 1 will be set to 1, values below 0 will be set to 0. Opacity is multiplied by the alpha channel of the active color (first or second color). Default opacity value is 0.2.

public double Opacity {get; set;}

Return Value

double

FirstColor

Summary

public string FirstColor {get; set;}

Return Value

string

SecondColor

Summary

Cloud color when the second line is above the first one. If not specified, color of the second line is used.
