NOTE
Use our DevExpress BI Dashboard to embed interactive business intelligence into your next web app.
The Web Dashboard is a data analysis UI component that you can embed into your ASP.NET Core or Angular, React, and Vue applications with .NET backend. Dashboards allow you to display multiple inter-connected data analysis elements such as grids, charts, maps, gauges, and others: all within an automatically-arranged layout.
The set of components allows you to deploy an all-in-one solution and switch between Viewer and Designer modes directly on the web client (includes adaptive layouts for tablet & mobile).
The Web Dashboard is available as a part of a Universal subscription.
