Visualizations → Stacked Line

About a Stacked Line visualization

A stacked line visualization plots data as points connected with lines. These lines are stacked and non-intersecting, where each line represents a different group of data. You can use a stacked line visualization to analyze data with different units of measure.

A stacked area visualization is ideal for displaying both nominal or ordinal data as a chart. Nominal data is categorical. These nominal categories are arbitrary labels without numerical significance that function to describe calculated values. Ordinal data has a natural sequence where the distinct (and often numerical) order functions to categorize the calculated values.

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

With three possible dimensions, a stacked line visualization offers a dashboard developer the ability to create an insight that groups one or more aggregated values by one or more attributes. The result is a stacked line chart on a dashboard tab that shows:

  • a grouping dimension as the labels along the x-axis (horizontal axis)
  • a coloring dimension as line colors
  • a measure as numerical increments along the y-axis (vertical axis)

Configurations for a stacked line insight

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

Important

A stacked line insight requires at least one measure pill and one grouping dimension pill. Using a measure pill only without a grouping dimension results in an insight with one point that represents the percentage for this measure.

Note

The Coloring Dimension tray is not available when there are two or more measure pills.

Grouping Dimension

From the Data panel, you can add a column or a formula to the Grouping Dimension tray. The stacked line insight plots the first pill in the Grouping Dimension tray on the x-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 lines in the chart. Each pill in the Coloring Dimension tray is a filterable column for the insight.

A defined coloring dimension introduces a Filter by menu as a user interaction for the stacked line 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 line insight shows the increments of the total percentage for the measure pill on the y-axis. A stacked line 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 lines for the stacked line 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.

Note

The Aggregate Filter tray is not available for a stacked line insight with one or more coloring dimension pills.

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:

You can edit the properties of a grouping dimension, coloring dimension, or a measure pill with the Properties panel for a stacked line 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 line insight

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

    Note

    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 stacked line insight:

    • Select a legend label to hide (and then select again to show) the related line
    • Select a point on a stacked line border to drill down into a grouping dimension and in doing so, create a dashboard runtime filter
    • Select a point on a stacked line border to open the Filter by menu and select an 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 (requires a dashboard drill down configuration for a coloring dimension or grouping dimension pill)
    Note

    A dashboard runtime filter that 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 stacked line 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.
