Setting up a correlation visualisation

Correlation visualisations are useful when you're examining the relationship between two pieces of data.

 

Configuring your correlation axes

Group by: Choose how you want your data to be grouped in the visualisation. For example, here it has been set to "People" meaning that each data point on the graph represents a person.
Axes: For each of the axes, you can use the top box to label the axis on the visualisation. The second box is a dropdown menu that you use to select how you want the data to be analysed, and the third is used to select which information from an xAPI statement should be analysed. Each axis also has a Query toggle that lets you add an optional extra filter built in the query builder.
