Create a box plot data visualization

Use a box plot to show the median and lower and upper quartiles of numeric data along with outliers. You can also compare the distribution of different groups of this data.

Before you begin

Important:

The box plot visualization is included in the latest data visualizations application from the ServiceNow® Store.

Role required: Anyone with access to data can create a visualization of that data on any dashboard that they can edit. 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

The Box Plot visualization only supports table data. Indicator, MetricBase, and User Experience Analytics data is not supported.

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

Procedure

1. Navigate to All > Platform Analytics > Library > Data Visualizations.
2. Select New.
3. Select the Box Plot () visualization type.

   Hide axis	Option to hide the primary axis.
   Primary axis title	Title to display on the vertical axis of the visualization. This property applies only when Hide primary axis is false. If there is more than one Y-axis, you have additional axis titles, representing the properties yAxis1Title, yAxis2Title, etc. Add a Y-axis scale for a metric in the More options menu for the metric.
   Axis range - from	Starting point for the values on the primary axis.
   Axis range - to	End point for the values on the primary axis.
   Axis position	Position of the primary axis. Options include: Left Right This property applies only when Hide axis is false. If there is more than one primary axis, such as multiple Y axes on a vertical bar visualization, you can set each axis position separately.
   Show grid	Shows a grid of fine lines perpendicular to the primary axis, to help align values against that axis.
   Axis style	Style of the primary axis. Clean clean: Adds a straight line to the primary axis. No tick lines noTicks: Option to remove all marks from the primary axis. Standard default: Adds a line and tick marks to the primary axis.
   X axis

Single color/Colors per metric: Select a single color in the Set value color field. Interacting with that field opens a selector where you can choose the color from either a set of icons or from a list. You can also search for a color. Entering a search value has the selector show you a list of colors filtered by that search value.

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