About an Area visualization

An area visualization is similar to a line visualization; however, it allows you to visualize volumes. An area visualization can show the trend of how specific values change over time or across categories. You can use an area visualization to showcase data that depicts a time-series relationship.

Information in an area visualization is plotted on an x-axis and y-axis; data values are plotted using data points that are connected using line segments. You can use area visualizations when you need to communicate the magnitude of the trend rather than individual data values. To showcase this magnitude, the area between the line segments and the x-axes is highlighted by filling it with color.

An area visualization allows you to compare volumes. The size of the area is proportional to the represented value.

An area visualization is ideal for displaying both nominal or ordinal data as a chart. Nominal data is categorical. The 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.

With three possible dimensions, an area 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 an area chart on a dashboard tab that shows:

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

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

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

Note

An area 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 result of the aggregated function for this measure, by default, the sum of 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 area 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 areas 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 area 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.

An area insight shows the increments for the measure pill on the y-axis. An area 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 area 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 an area insight with one or more coloring dimension pills.

To create a filter expression, 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 an area insight.

To create a filter expression, 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 an area insight

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

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

    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 an area 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, review Tools → Security Manager.

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