On the Data Selection tab, you select the data source and view to use for the chart. You also determine the maximum number of records to display on the chart.

To select the data source and view:
The list of views is updated to display the available views for the selected data source.
If you had already configured the chart, then when you select a different data source, you are prompted to select whether to try to maintain the existing configuration with the new data.
If the number is greater than this value, then the chart is not displayed, and an error message is displayed to the end user.
