Pie with Custom Fill Styles

This demo uses custom patterns and gradients for PieChart slices.

Gradient

Call the registerGradient() method to obtain a gradient ID. Specify method arguments as follows:

• type
  This method supports two gradient types: 'linear' and 'radial'.

• options
  An object for gradient options.

  • colors
    An array of gradient colors. Each color is an object that includes color and offset fields. The offset field specifies the starting point for each color.

  • rotationAngle (linear gradients only)
    You can use this option to rotate linear gradients.

Pattern

To obtain a pattern ID, call the registerPattern() method. Specify method arguments as follows:

• options
  An object with pattern options.

  • height
    Template height.

  • width
    Template width.

  • template
    A repeating SVG-based template that creates the required pattern.

Fill the PieChart

To fill all slices with the same pattern or gradient, assign a pattern ID to series.color.fillId. If you want to customize each slice individually, implement the customizePoint function (review this demo for more information).

Custom patterns and gradients are not limited to the PieChart. The following DevExtreme components support the use of patterns/gradients:

• Chart

• PolarChart

• CircularGauge

• LinearGauge
