Grid data chart in Angular Chart component

18 Nov 20185 minutes to read

You can visualize the data that is returned by the grid in the chart.

To visualize the data in the chart, follow the given steps:

Step 1:

Initialize the grid with a dataSource.

Step 2:

By using the grid’s actionComplete event and getCurrentViewRecords method, you can get the current page records whenever paging, sorting, or filtering occurs.
By using the grid’s dataBound event, you can update the current page records into the chart’s dataSource and visualize the grid data in the chart on initial load.
