About a Donut visualization
A donut visualization is a circular visualization that has only one series, each point of which is a part of a whole. All values are in percent by default.
A donut visualization is a variant of the pie visualization. The donut visualization is ideal for showing the proportions of categorical data, with the size of each piece representing the proportion of each category.
The distinction between a visualization and an insight is that an insight is an instance of the visualization. As an instance, an insight has unique configurations that a dashboard developer determines for displaying a chart on a dashboard tab. Insight configurations affect the available user interactions for a dashboard consumer such as the ability to drill down into a grouping dimension.
With two possible dimensions, a donut visualization offers a dashboard developer the ability to create an insight that groups one or more aggregated or calculated values by one or more attributes. The result is a donut chart on a dashboard tab that shows:
- a grouping dimension element
- a measure
Configurations for a donut insight
A dashboard developer first selects a donut visualization for an insight in the Analyzer. Using the Analyzer, a dashboard developer configures pill properties, filter properties, and insight settings. Insight settings and pill properties determine not only how the donut chart appears as an insight in a dashboard tab, but also how a dashboard consumer can interact with the donut chart.
The visualization selection in the Insight panel of the Analyzer determines the available trays. From the Data panel, a dashboard developer adds a column or a formula to a tray. A column or a formula in a tray is a Pill.
Each pill has configurable properties. The parent tray determines the available properties of a pill.
The available trays for a donut insight are:
The donut insight does not accept, or display, zero or negative values.
Grouping Dimension
From the Data panel, you can add several columns or formulas to the Grouping Dimension tray. The donut insight plots the first pill in the Grouping Dimension tray.
Each pill in the Grouping Dimension tray is a filterable column for the insight. The pill ordering in the grouping dimension tray defines the following:
- the first pill is the innermost element as the parent node
- the other pills define an order of user interactions that allow a dashboard consumer to drill down into the next grouping dimension and in doing so, also create one or more dashboard runtime filters
Measure
To create an aggregation or calculation, you can add a column or a formula from the Data panel to the Measure tray.
You can select the measure pill to open the Properties panel. In the Properties panel, you can configure various properties such as the Aggregation and Format properties.
Tooltip
To show a tooltip as an aggregation or calculation, you can add a column or a formula from the Data panel to the Tooltip tray.
An insight shows the chosen aggregation for the tooltip pill when hovering on a certain point on the insight. The tooltip tray is optional as it accepts none, one, or multiple pills.
You can select the tooltip pill to open the Properties panel. In the Properties panel, you can configure various properties such as the Aggregation and Format properties.
Individual Filter
To filter data for the donut insight, define an individual filter for the insight. You can add a column or a formula to the Individual Filter tray from the Data panel.
You can select the individual filter pill to open the Filter panel. Using the Filter panel, you can specify the filter operator, one or more filter values, or the filter expression itself with the Formula Builder. You can also disable the individual filter.
To learn more about filter expressions for an individual filter, review Concepts → Individual Filter.
Aggregate Filter
You can define a filter expression that contains an aggregation or calculation using the Aggregate Filter tray.
To create a filter expression, you can add a column or a formula to the Aggregate Filter tray from the Data panel. You can select the aggregate filter pill to open the Filter panel.
Using the Filter panel, you can specify the aggregation, the filter operator, one or more filter values, or the filter expression itself with the Formula Builder. You can also disable the aggregate filter.
To learn more about filter expressions for an aggregate filter, review Concepts → Aggregate Filter.
Pill properties
The parent tray determines the available properties of a pill. There are various possible configurations for each pill type:
- Grouping dimension pill properties
- Measure pill properties
- Tooltip pill properties
- Individual filter properties for a filter expression
- Aggregate filter properties for a filter expression
You can edit the properties of a grouping dimension or a measure pill with the Properties panel for a donut insight.
To create a filter expression, you can edit the properties of an individual filter or aggregate filter pill with the Filter panel.
In the case of the Filter property of a measure pill, you can open the Filter panel from the Properties panel to create the filter expression.
To open the Properties panel or Filter panel, select the pill arrow.

User interactions for a donut insight
As a dashboard consumer, you can interact with a donut insight on a dashboard tab. Some interactions will affect only the donut chart. Other interactions will affect both the donut chart and the dashboard. The creation of one or more dashboard runtime filters is an example of a user interaction that affects all applicable insights on all tabs of a dashboard.
Some user interactions require specific configurations by a dashboard developer and therefore may not be available.
Here are the possible types of user interactions for a donut insight:
- Select a ring piece to drill down into a grouping dimension and in doing so, create a dashboard runtime filter
- Select a ring to open the Filter By menu and select an option to drill down into a grouping dimension and in doing so, create a dashboard runtime filter
- Select a dashboard tab to navigate to in the Go To menu
A dashboard runtime filter affects all applicable insights on all tabs of a dashboard. A dashboard runtime filter appears as a filter bar pill and displays the filter expression.
More Options menu for a donut insight
Role-Based Access Control (RBAC) enforces access to certain features and functionality. With Discretionary Access Control (DAC), a user who owns the dashboard can control the access to the dashboard. Access rights include the ability to view, share, and edit the dashboard. Together, RBAC and DAC affect the available selections in both the Action bar and the More Options menu for an insight.
For more information about RBAC and DAC, refer to the Security Manager documentation.
In addition, certain tenant configurations by a Cluster Management Console (CMC) Administrator affect the available selections in the More Options menu for an insight.
