Strokes

The stroke colors of the pie segments.

Declaration

[Parameter]
public IEnumerable<string> Strokes { get; set; }

Property Value

Type	Description
IEnumerable<string>

TotalAngle

Gets or sets the total angle of the pie in degrees. Set to 360 by default which renders a full circle. Set to 180 to render a half circle or

Declaration

[Parameter]
public double TotalAngle { get; set; }

Property Value

Type	Description
double

X

Y

Specifies the y coordinate of the pie center. Not set by default which centers pie vertically.

Declaration

[Parameter]
public double? Y { get; set; }

Property Value

Type	Description
double?	The y.
