Angular CircularGauge - 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(){
    $("#circularGaugeContainer").dxCircularGauge({
        // ...
        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"
                            }]
                        }) 
                    } }
                ]
            }
        }
    });
});
