A Scatter chart displays points that show the relationship between two sets of data. First you need to generate a Table Chart then modify the chart to create a Scatter chart.
For example, QA Manager want to view Test Case authoring daily progress - Draft Vs Approved For Execution.
The fields required in the report are: Test Case Created Date, Test Case Status, Test Case Entity Key
X-Axis: Label always holds a single test entity field with any value.
Y-Axis: It always contains fields with numeric values. Multiple test entity fields on Y-Axis create a stacked chart.
Cross Tab: It helps to create a Group Stacked chart. A simple table only shows the relationship between two variables. Whereas a Cross Tab shows the relationship between two or more variables in the table/chart.
