Donut charts

Donut and semi-donut charts show the proportions that make up a whole.

Donut charts are similar to pie charts, but the donut chart has empty space in the middle. The difference between a donut and a semi-donut chart is that a semi-donut is a donut sliced in half. The information presented is the same. Donut and semi-donut charts can be placed on homepages where users can quickly interpret the information displayed.

For example, use a donut or semi-donut chart to show open incidents by priority. At any time, there are open incidents of different priority levels. A donut or semi-donut chart enables you to see quickly whether incident counts of different priorities are within acceptable ranges.

Create a donut report

How to create a donut report.

Before you begin

Role required: itil, report_group, report_global, report_admin, or admin. To create a meaningful report, you must have the right to access the data you want to report on.

Procedure

  1. Navigate to Reports > Create New.
  2. Fill in the fields, as appropriate.
    Field Description
    Name Enter a unique and descriptive name for the report.
    Description Click the information icon (Detailed description) to enter a more detailed description of what the report does and its purpose.
    Data Specify the table or report source containing the data set that you want to include in the report. From the first choice list, select the Table or Report source. Then select the specific table or predefined data set from the second choice list.
    Type

    Select Donut or Semi donut.

    Style your chart Click the gear icon (Cogwheel) after the Type field to configure chart style options for the look and layout of the chart.
    Group by Select a field to organize data into groups from the selected table. For example, in an incident report that is grouped by Assignment group, all incidents belonging to Software, Service Desk, Network, and so on, are placed in separate groups. Make sure you give the report a name that reflects the field you select.

    Click plus icon to select additional group by fields. When you select Additional group by fields, a control is added to the bottom of the report that groups the report by any one of the additional fields.

    Note: It is not possible to group or stack reports by the Tags field.
    Display Grid Select this check box to display details of the report data in a table below the chart.

    All reports that use charts, including reports that are used on homepages, display a table of report data when the glide.ui.section508 system property is set to true, even if Display Grid is cleared.

    Aggregation Select a computational method for aggregating report data. The default is Count, which displays the number of records selected.

    If you select Count Distinct, only unique records are counted. For example, if you want to generate a report with a distinct number of users who have one or more of the roles in a given list of roles, these users would be counted twice unless you use count distinct.

    If you select Average, Sum, or Count Distinct, a list of fields from the selected Table appears. From this list, select a field to aggregate by. For example, if you select a duration field, such as the Business duration field on the Incident table, the aggregated data is expressed in days, hours, and minutes. If you select an integer field, such as the Priority field, the data is expressed as a number.

    Note: For duration values, the unit of measurement displayed in the aggregation axis cannot be customized.
    No. groups Select the maximum number of individual values that can be represented as slices in the chart. If the number of values from the selected data exceeds this limit, only the largest values are represented by the slices. By default, up to the 12 of the largest values from the selected data can be represented. Remaining values are grouped into an Other slice.

    If you select Show all, all slices up to limit of 50 slices can be displayed. The rest of the results are stacked in the Other slice. If you select Remove Other, the Other slice is hidden.

    Show Other Select this check box if you want to display the Other slice. This check box is not available when Show all or Remove Other are selected from the No. groups list.
    Add Filter Condition Create conditions for filtering data to include in the report. For example, to include only records with priorities of 2- High and 1 - Critical, select [Priority] [less than] [3 - Moderate].
    Note: Applying a string filter with other filters to donut and bar charts is not supported.
    Add "OR" Clause Select a second condition that must be met if the first condition is invalid. For example, select [Assignment Group] [is] [Database], to include records that are assigned to the Database group if the first condition is false.
    Add Sort Field Select fields to sort data by. For example, to sort results from lowest to highest priority, select [Priority] [z to a].
  3. Click Save. The report is generated.

What to do next

Add reports to homepages or dashboards, publish to the internet, schedule email distribution of PDFs or URLs of published reports, and share reports with others. For more information, see Distribute reports.
