Car dials are the most famous example of what the Telerik UI for Blazor Radial Gauge represents – effectively a linear scale bent around a center point, so it takes space more evenly in both directions instead of being a single absurdly long line. Prefer the radial approach when you want the user to be gather all the information immediately at a glance.
The Radial Gauge can have as many pointers as you need to present different values on the same scale. The pointers themselves can be customized by changing their color which makes distinguishing the different values happen on first glance.
The Radial Gauge’s scale be split into several ranges when they mean different things. The red zone on your car’s tachometer is an example of separate range – you don’t want your revolutions pointer entering that zone and you might want to provide the same visual feedback for your users’ data. A variety of other factors can similarly be modified – the colors of the scale and labels, which ticks are displayed and which aren’t, the initial angle, etc.
