Donut charts

Donut and semi-donut charts are useful when comparing the size of parts to the whole.

They are very 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. The organization may have a policy stating that P1 incidents can never exceed 40% of all open incidents. With a donut or semi-donut chart, you can quickly see if incident counts are within acceptable ranges.

Create a donut chart report

How to create a donut chart 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 (The information icon) 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.

    Alternatively, click the question mark icon (The question mark icon) to use the report type selector.

    Style your chart Click the gear icon (The gear icon) after the Type field to configure the 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 grouped by Assignment group, all incidents that belong to Software, Service Desk, and Network are placed in separate groups.
    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 dashboards, display the table of report data when the glide.ui.section508 system property is set to true. The glide.ui.section508 property overrides the Display data table field.

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

    Select Count Distinct to display only unique records. For example, 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. Users with more than role 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. Select a field to aggregate by from this list. For example, if you select a duration field, such as Business duration on the Incident table, the aggregated data is expressed in days, hours, and minutes. If you select an integer field, such as Priority, the data is expressed as a decimal value number.

    Note: For duration values, the unit of measurement displayed in the aggregation axis cannot be customized.
    No. groups

    Select the maximum number of groups such as bars, sections, or columns, that can be displayed in the chart. If the number of values from the selected data exceeds this limit, only groups for the largest values appear. By default, up to 12 of the largest values from the selected data are represented. Remaining values can be grouped on the Other bar.

    If you select Show all, all groups up to a limit of 50 are displayed. The rest of the results are grouped as Other. If you select Remove Other, the Other group is hidden.

    Show Other Select this check box to display the Other group for values that exceed the No. groups limit. This check box is not available when Show all or Remove Other is selected from the Max number of 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.
    Donut chart configure

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. See Distribute reports.
