Create a bubble visualization in the Visualization Designer

Use a bubble visualization to show multiple separate metrics on a single chart. Use bubble charts to answer binary questions, such as whether two fields have a relationship, and to highlight patterns.

Before you begin

Role required: Anyone with access to data can create a visualization of that data on a dashboard that they own. Users with the itil, report_user, admin, or viz_creator role can create a visualization in the Visualization Designer. If you create a visualization in the Visualization Designer, it is saved to the Library. For more information on access, see Report_view access control and Platform Analytics roles.

About this task

For information about the use of a Bubble visualization in a dashboard, see the Developer Site. This site gives information about Bubble data visualization components in the UI Builder, and some configuration options may differ from the Visualization Designer.

Bubble visualizations aggregate information over three different metrics, using the X axis, Y axis, and bubble size.

Procedure

1. Navigate to All > Platform Analytics > Library > Data Visualizations.
2. Select New.
3. Select the Bubble () visualization type.
4. Configure the Header and border. Header and border options are the same for all data sources.

   Header and border fields	Description
   Show header	The visualization header, including title and icons.
   Show header separator	Option to display a line separating the header from the rest of the component.
   Chart title	Title of the visualization.
   Description	A short overview about the visualization that the end user sees.
   Wrap title	Option to wrap long titles onto a second line. If false, displays an ellipsis to truncate long titles.
   Show border	Option to display a line around the component.
   Bare	Option to remove padding around data visualization to provide more compact positioning on the page. Only available when Show border is turned off.

5. Choose a data source.
   For general descriptions of the data sources, see Data sources for data visualizations.

   You can choose one or more tables (available in the base system). When you select a table, you can filter it by conditions.

   Note:

   You can choose to define a data source manually in JSON. However, this method is intended only for experts.
6. Select the options for your data source.
   Go to Table data options for bubble visualizations.
7. Under Presentation, provide display and color information. In the Colors section, configure the colors and color rules.

   Field	Description
   Show data table	Shows a table with chart and graph data for easier screen reader access. Data includes the percentage of the total for each value, when appropriate.
   Show legend	Available when you configure a group by or have more than one metric. Select to display the legend.
   Legend position	Legend location relative to the chart: Above, Below, Right, or Left.
   Set color type	Default: A color or set of colors that come from the UX Theme that is applied to the instance. For more information, see Working with themes in Next Experience. Single color/Colors per metric: Select a single color in the Set value color field. You can select the color from a set of icons, from a list of colors including their icons, or by searching for the color name or hexadecimal value. The colors are taken from the Color Definition [sys_report_color] table.

8. Under Chart interaction, set what if anything happens when a viewer clicks a chart or a chart segment on the visualization.

   Field	Description
   Allow chart interaction	Enable an event to occur when a user clicks in a chart or one of its segments.
   Action	Choose the event that occurs when a user clicks in a chart or one of its segments. Choices depend on the visualization type and data source. Applies only when Allow chart interaction is on. For more information, see Chart interactions in a data visualization. Go to data view opens the records view in a Core UI list or KPI Details relevant to the associated segment or visualization. Records do not open in Workspace embedded lists. Not supported for Usage Insights data sources. Go to URL opens the specified URL, which can be on the instance or external. You have the option of specifying a page name to appear in the tooltip, for those visualizations with tooltips. Drill down to chart (Visualization Designer only) Opens a different data visualization that is filtered by the selected data. You can add a drill-down visualization for each metric on the parent visualization. Note: The last level of drill down in the Platform Analytics experience is always a Core UI list. Records do not open in Workspace embedded lists. Drill down to chart supports only table data sources. It requires the latest Platform Analytics application from the ServiceNow® Store.

9. Select Save to continue editing the visualization, or Save and close to return to the Analytics Overview main screen.

What to do next

• Add a visualization to a dashboard from the Visualization Designer
• Select the More actions menu icon () to duplicate, share, export, schedule, or bookmark the visualization.
