The number of pie chart reports returned depends upon whether the data property hostname is included in the report request. The report returns data as one pie chart per host if hostname is specified in the report request. If the data property hostname is not specified in the report request, only one pie chart is generated in the report. Pie chart reports are not available for performance and hardware configuration reports when the Level of Detail:Summary option is selected. The pie chart icon is a circle with a single line that depicts the radius.
