About a Stacked Bar Visualization

A stacked bar visualization allows you to compare the components of a total quantitative value across a range of different categorical values.

A stacked bar visualization is ideal for displaying grouped data using rectangular bars whose lengths are proportional to the values they represent. One axis of the chart shows specific categories you are comparing, and the other axis represents a measured value. Some bar graphs present bars clustered in groups of more than one, showing the values of more than one measured variable.

With three possible dimensions, a stacked bar 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 stacked bar chart on a dashboard tab that shows:

• a grouping dimension as the labels along the y-axis (vertical axis)
• a coloring dimension as vertical columns colors
• a measure as horizontal bar lengths with increments along the x-axis (horizontal axis)

The distinction between a stacked bar visualization and a stacked bar insight is that an insight is an instance of the visualization. As an instance, a stacked bar insight has unique configurations that a dashboard developer determines for displaying a stacked bar 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 and/or coloring dimension.

Configurations for a stacked bar insight

A dashboard developer first selects a stacked bar 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 stacked bar chart appears as an insight in a dashboard tab, but also how a dashboard consumer can interact with the stacked bar 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 stacked bar insight are:

• Grouping Dimension
• Coloring Dimension
• Measure
• Individual Filter
• Aggregate Filter

Grouping Dimension

From the Data panel, you can add a column or a formula to the Grouping Dimension tray. The stacked bar insight plots the first pill in the Grouping Dimension tray on the y-axis.

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 initial grouping dimension
• the other pills define an order of user interactions that allow a dashboard consumer to drill down into the next grouping and/or coloring dimension and in doing so, also create one or more dashboard runtime filters.

Coloring Dimension

The Coloring Dimension tray is only available when there is only one measure pill.

From the Data panel, you can add a column or a formula to the Coloring Dimension tray. A coloring dimension is a third dimension that colors the horizontal stacked bars in the chart. Each pill in the Coloring Dimension tray is a filterable stacked bar for the insight.

A defined coloring dimension introduces a Filter by menu as a user interaction for the stacked bar chart. With the Filter by menu, a dashboard consumer selects to filter the dashboard by:

• a grouping and a coloring dimension
• a grouping dimension
• a coloring dimension

The pill ordering in the coloring dimension tray defines the following:

• the first pill is the initial coloring dimension
• the other pills define an order of user interactions that allow a dashboard consumer to drill down into the next grouping and/or coloring 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.

A stacked bar insight shows the increments for the measure pill on the x-axis. A stacked bar insight with two or more measure pills does not support the definition of a coloring dimension.

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.

Individual Filter

To filter individual rows for the stacked bar 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
• Coloring dimension pill properties
• Measure 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, coloring dimension, or a measure pill with the Properties panel for a stacked bar insight.

In order 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 in order to create the filter expression.

To open the Properties panel or Filter panel, select the pill arrow.

User interactions for a stacked bar insight

As a dashboard consumer, you can interact with a stacked bar insight on a dashboard tab. Some interactions will affect only the stacked bar chart. Other interactions will affect both the stacked bar 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.

Here are the possible types of user interactions for a stacked bar insight:

• Select a legend label to hide (and then show) the related vertical column
• Select a vertical column to drill down into a grouping dimension and in doing so, create a dashboard runtime filter
• Select a vertical bar to open the Filter by menu and select a option to drill down into a grouping dimension and/or coloring dimension and in doing so, create a dashboard runtime filter
• Select a dashboard tab to navigate to in the Go to menu

More Options menu for a stacked bar insight

Role-Based Access Control (RBAC) enforces access to certain features and functionality. With Discretionary Access Control (DAC), a user who owns the dashboard to 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.

In addition, certain tenant configurations by a Cluster Management Console (CMC) Administrator affect the available selections in the More Options menu for an insight.
