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

  1. Bind the chart to a ASP.NET Core DataSource control.
  2. Set the property to the name (e.g., the "Symbol" field) 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 corresponding data source field (e.g., the "Date" and "Close" fields): series.ScatterLine(model => model.Date, model => model.Close)

This will result in as many series as the number of distinct values in the column (e.g., “Symbol”).  Since the “Symbol” field in this example contains three distinct values (“1. GOOG (close)”, “2. AAPL (close)” and “3. AMZN (close)”) the chart will create three series as well.
