ASP.NET Core Bar Charts Binding to Grouped Data

Telerik Core charting extension can be integrated to a grouped data by ASP.NET Core DataSource. To do so you can follow the following steps:

1. Bind the Telerik UI for ASP.NET Core chart to a ASP.NET Core DataSource control.
2. Set the DataSource.Group property to the name of the column in the underlying data which will be the criteria for grouping the chart series items into series: Group(group => group.Add(model => model.Symbol)
3. Bind the Y values of the series to the “Close” field: series.Area(model => model.Close)
4. Bind the Category Axis to the Date field: .Categories(model => model.Date)

This will result in as many series as the number of distinct values in the column (i.e., DataSource.group.field). For each value there will be a chart series in the chart.

This Bar Charts example is part of unique collection of hundreds of ASP.NET Core demos, with which you can see all Telerik ASP.NET Core components and their features in action. View the source code of the demos from the library or directly adapt, and edit them and their theme appearance in Telerik REPL for ASP.NET Core or ThemeBuilder.
