The RadialGauge component is part of Telerik UI for Blazor, a professional grade UI library with 110+ native components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.
The Telerik UI for Blazor Radial Gauge represents numerical values on a scale of ranges in a radial format. It is one of the four gauge UI components available in the Telerik UI for Blazor data visualization collection that lets you visualize data values against a scale to easily identify them as suitable or sub-par values. In the radial gauge, the dial is a section of a circle with a needle pointing to the value, resembling a car speedometer or physical gauge devices.
In the current demo, you can see a primary example of the Telerik Radial Gauge component in Blazor applications. The gauge is added to a razor file by plugging the <TelerikRadialGauge> tag and configuring values for the scale and pointer. To interact with the component, you can change the pointer values and see how the radial gauge pointer updates its value on the scale.
The pointers in the Telerik UI for Blazor Radial Gauge consist of a pointer arrow and a pointer cap—the circle that marks the pointer center. You can customize the pointer arrows and caps through the parameters they expose: pointer arrow color and length, and pointer cap color and size. In case you need to add more than one pointer, you can easily achieve that by adding as many instances of the <RadialGaugePointer> tag as you need within the <RadialGaugePointers>.
The customization settings in the Radial Gauge component include minimum and maximum values, minor and major unit ticks, reverse scale, start and end angle of the scale, range size, distance, opacity and color, as well as labels color, position, visibility and format. In case you need to re-render the Telerik Radial Gauge programmatically, you can take advantage of the exposed Refresh method.
