JavaScript/jQuery PolarChart - Customize Appearance
To change series color, use one of the following options:
- Specify a color palette for the component.
- Specify a color for a series.
- Specify a color for all series.
Besides color change, you can add a custom pattern or gradient fill to the following series:
Use the registerPattern() or registerGradient() method to create a custom pattern or gradient.
The following example adds a gradient to all series in a PolarChart:
jQuery
index.js
const registerGradient = DevExpress.common.charts.registerGradient;
$(() => {
$('#polarChart').dxPolarChart({
// ...
commonSeriesSettings: {
color: {
base: "#f5564a",
fillId: registerGradient("linear", {
colors: [{
offset: "20%",
color: "#97c95c"
}, {
offset: "90%",
color: "#eb3573"
}]
})
}
}
});
});Angular
