Gauges

Overview

DevExtreme HTML5 JavaScript Gauges is a set of interactive React components for visualizing data on dashboards. This set includes two circular and one linear gauge. The Gauges operate in controlled or uncontrolled state mode and can be used with Redux. Declared PropTypes for typechecking are included. Learn more about DevExtreme React components on GitHub.
