Overview
DevExtreme HTML5 JavaScript Gauge widgets are interactive Angular components for dashboards. They come in two geometric shapes - circular, or radial, and linear - and provide a comprehensive set of features including multiple value indicators, geometry customization, interactive tooltips, palettes support, and many more. Native Angular features, like AOT compilation, declarative configuration, TypeScript compile-time checking, are supported as well.
Feel free to share demo-related thoughts here.
If you have technical questions, please create a support ticket in the DevExpress Support Center.
Thank you!
We appreciate your feedback.
