Highcharts - Pie Chart with Gradient
Following is an example of a Pie chart with gradient.
We have already seen the configuration used to draw a chart in Highcharts Configuration Syntax chapter.
An example of a Pie chart with gradient is given below.
Configurations
Let us now see the additional configurations/steps taken.
colors
Configure the colors of a chart using the Highcharts.getOptions().colors property.
// Radialize the colors Highcharts.getOptions().colors = Highcharts.map( Highcharts.getOptions().colors, function (color) { return { radialGradient: { cx: 0.5, cy: 0.3, r: 0.7 }, stops: [ [0, color], [1, Highcharts.Color(color).brighten(-0.3).get('rgb')] // darken ] }; } );
