The Scatter Matrix panel takes two or more data columns and plots them against each other in every possible combination. For example, if you have two columns, A and B, running the Scatter Matrix dashboard results in four plots:
•A on X axis/B on Y axis
•A on X axis/A on Y axis
•B on X axis/A on Y axis
•B on X axis, B on Y axis
Selecting three columns would result in nine combinations, four in sixteen combinations, and so on.
To generate a Scatter Matrix dashboard:
1.Select the Scatter Matrix tab in the Custom Dashboard commands.
2.Select a column to serve as a Key Value. The key column is a partition key, a value to group the rows by, or in this case, the visualization of the rows. This column should have a limited number of values.
3.Click the + icon to add the suggestion to the Script.
4.Click the Dashboard icon in the script.
5.The Scatter Matrix dashboard opens.
