Description

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 chart to a ASP.NET Core DataSource control.
  2. Set the DataSource.group.field 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.
