You can drag and drop attributes or measures into a particular breakdown in the Analyzer tool.
In the example below, the Average Total Views measure has been added to the Y axis and the Content Type attribute has been added to the X axis of this column chart. The column chart shows the average number of content views per content type in Fuse.
If you select the Table insight, you will see Measures, Rows, and Columns. In this case the rows and columns are used to break down the data in a table.
If you select the Line chart option, the applicable breakdowns are Measures, Trend By, and Segment By. In this case, Trend By and Segment By are used to break down the data on line chart.
To remove a particular attribute or measure from a breakdown, drag it back into the Data Catalogue
