Note: If the default data source is configured in the Reporting Engine, then the data source is displayed by default on the Build Chart page. If the data source is not displayed, ensure you have Read permissions set for the data source. This is applicable for NWDB and Warehouse data sources. For more information, see the "Configure Data Source Permissions" topic in the Host and Services Configuration Guide.

  1. (Optional) To modify the Interval value, click the up or down arrow.
    The Interval value is the interval in minutes at which the rule which forms the basis of the chart is run to collect data.
  2. Select the Limit value to limit the number of records to be displayed.
  3. X-Axis and Y-Axis are used to specify the meta to be plotted in charts.
    In the X-Axis, the meta for the 'Group by' rule is displayed. In the Y-Axis, the aggregate functions used in the rule are displayed.

Note: Sum, Count, Countdistinct and Average are the supported aggregate functions for chart. By default, for Custom Rules with multiple 'Group by', you can select only the first meta in X-Axis.

    A confirmation message that the chart is saved successfully is displayed.
