Overview
The scatter plot chart is used to display the relationship between numeric values. The numeric values are represented by dots, and the position of the dots on the vertical and horizontal axes indicates the value on the associated variable.
Configuration
To plot a Scatter Plot chart, perform the following steps –
1. Open the Analytics page and click the Add Widget icon. The Analytics Builder appears.
2. Click the Scatter Plot chart. The Settings page appears.
3. Enter the given information in the Data Criteria and Dimension and Settings as per your requirements.
- Widget Name – Modify the widget name if required.
Data Criteria
- Select Workitem type – Select the workitem type for which you want to plot the chart. You can select any number of workitems for a scatter chart. If the selected workitem type has no instances in it, a message is displayed on the screen.
Note: If you select the My Workitem option, the Release, Sprint, and Task Plan options won’t be selected as they are dependent on the form’s execution. - Select workitem status – Select the workitem status such as All, Open, Closed, etc. for the workitem types.
- Select Filter – Select the filter that you want to apply on the workitems for the scatter chart. You can also create a new filter.
- Date Range – Select the start date and the end date under the data criteria to plot the chart. By default, it loads the Project start and end dates.
Dimensions and Settings
- Select aggregation – You can plot the chart based on the numeric field of the selected workitem type such as count, sum, percentage etc.
Select Axis on the chart
- X Axis – Select the attribute (and its values) which you want to be plotted on the X axis of the chart. The attribute field shows all the fields which are common in the selected workitem types.
- Group Y – The Group By option lets you view the data points in different groups as per their selected attribute such as workitem type.
Interpretation
Each dot in a scatter plot chart represents a value of the attribute selected for X axis. These values are grouped by the numeric field selected for aggregation like count of the workitems, sum, percentage etc. For example, if you have Size for the X axis attribute, then each dot on the chart represents a size like L, M, S etc. All the workitems of similar size are grouped together. The count and size of workitems can be shown by hovering over a dot.
Best use
A Scatter Plot chart works best when comparing large numbers of data points without regard to time. This is a very powerful chart type and suggested for showing the relationship between two variables (x and y axis).
