By default, the focal point of a radial gradient–the spot where the gradient starts–is at the center of the control in which it’s located.
You can specify a different focal point using the RadialGradientBrush.GradientOrigin property. The GradientOrigin property specifies the start of the gradient in 2D (X,Y) space, with X ranging from 0.0 (left side of control) to 1.0 (right side) and Y ranging from 0.0 (top) to 1.0 (bottom).
Here’s the same gradient as above, with the origin at (0.2,0.4).
