Setting The Background
RadChart offers a variety of ways to define backgrounds. Here are the main scenarios:
1. Solid color
… -> FillStyle -> FillType -> Solid
… -> FillStyle -> MainColor ->
2. Simple 2-color gradient
… -> FillStyle -> FillType : Gradient
… -> FillStyle -> MainColor ->
… -> FillStyle -> SecondColor ->
… -> FillStyle -> FillSettings -> GradientMode ->
3. Complex Gradient
… -> FillStyle -> FillType -> ComplexGradient
… -> FillStyle -> FillSettings -> ComplexGradient -> Collection ->
… -> FillStyle -> FillSettings -> GradientAngle ->
4. Hatch (2-color pattern)
… -> FillStyle -> FillType -> Hatch
… -> FillStyle -> MainColor ->
… -> FillStyle -> SecondColor ->
… -> FillStyle -> FillSettings -> HatchStyle ->
5. Custom Image
… -> FillStyle -> FillType -> Image
… -> FillStyle -> FillSettings -> BackgroundImage ->
… -> FillStyle -> FillSettings -> ImageAlign ->
… -> FillStyle -> FillSettings -> ImageDrawMode ->
… -> FillStyle -> FillSettings -> ImageFlip ->
6. Opacity
You can achieve opacity by specifying an alpha transparency to the color, in addition to the red-green-blue values. The alpha value should come first, like this:
[transparency level0 - 255]; [red 0 - 255]; [green 0 - 255]; [blue 0 - 255]
The greater the opacity value, the less transparent the background is.
