Setting The Background

RadChart has been deprecated since Q3 2014 and is no longer recommended for use, as it does not support modern browsers. We strongly recommend using RadHtmlChart, Telerik's modern client-side charting component. To transition from RadChart to RadHtmlChart, refer to the following migration articles:

• Migrating Series
• Migrating Axes
• Migrating Date Axes
• Migrating Databinding
• Features parity

Explore the RadHtmlChart documentation and online demos to determine how it fits your development needs.

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.
