The Kendo UI chart can be bound to grouped data using Kendo UI DataSource as a mediator. To do so you can follow the steps below:
- Feed data to the chart via Kendo UI DataSource instance.
- Set the DataSource.group.field 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 items into series
- Bind the Y values of the series to the corresponding data source field (e.g., the “Date” and “Close” fields)
This will result in as many series as the number of distinct values in the DataSource.group.field column. 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.
