Visualizations → Scatter
About a Scatter visualization
A scatter visualization allows you to represent and illustrate correlations between numeric variables. Information in a scatter visualization is plotted on an x-axis and a y-axis, where both the x and y dimensions are quantitative. Each entity represented in a scatter plot is assigned a symbol called a point shape. The point shapes in a scatter plot represent the values of individual data points as well as the patterns when the data are taken as a whole.
A scatter 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 categorize the calculated values.
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 scatter 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 scatter chart on a dashboard tab that shows:
- a grouping dimension as the categories
- a measure as an independent variable along the x-axis (horizontal axis) and a dependent variable along the y-axis (vertical axis)
Configurations for a scatter insight
A dashboard developer first selects a scatter 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 scatter chart appears as an insight in a dashboard tab, but also how a dashboard consumer can interact with the scatter 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 scatter insight are:
A scatter insight requires two measure pills and one grouping dimension pill.
Grouping Dimension
From the Data panel, you can add a column or a formula to the Grouping Dimension tray. The Grouping Dimension pill represents the categories in the Scatter insight, such as Product Category, or Subcategory.
Measure
To create an aggregation or calculation, you can add a column or a formula from the Data panel to the Measure tray.
A scatter insight plots the first measure pill as the independent variable on the x-axis and the second measure pill as the dependent variable on the y-axis.
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 individual rows for the scatter 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 scatter 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 scatter insight
As a dashboard consumer, you can interact with a scatter insight on a dashboard tab. Some interactions will affect only the scatter chart. Other interactions will affect both the scatter 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 scatter insight:
- Select a legend label to hide (and then select again to show) the related area
- Select a point on a scatter border to drill down into a grouping dimension and in doing so, create a dashboard runtime filter
- Select a point on a scatter border 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 point on a scatter border to open the Go to menu and select a dashboard tab to navigate to (requires a dashboard drill down configuration for a grouping dimension pill)
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 scatter 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.
