Update Circular Gauge Data at Runtime
Documentation
This demo illustrates how to bind an array of subvalues to the CircularGauge. Since an array can not be bound to a field as a regular value, it is bound as a computed one.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
