JavaScript/jQuery LinearGauge - Customize Appearance
You can use the following properties to colorize gauge elements:
You can also add a custom pattern or gradient fill to the elements. Use the registerPattern() or registerGradient() method to create a custom pattern or gradient.
The following example adds a gradient to one of the ranges in a gauge:
jQuery
index.js
const registerGradient = DevExpress.common.charts.registerGradient;
$(function(){
$("#linearGaugeContainer").dxLinearGauge({
// ...
rangeContainer: {
// ...
rangeContainer: {
ranges: [
{ startValue: 0, endValue: 50, color: '#92000A' },
{ startValue: 50, endValue: 100, color: {
fillId: registerGradient("linear", {
colors: [{
offset: "20%",
color: "#97c95c"
}, {
offset: "90%",
color: "#eb3573"
}]
})
} }
]
}
}
});
