To do a new usage comparison, select New Usage Comparison and add desired Features from All Features list to Features On Comparison grid.

2. Move desired features from All Features grid to Feature On Comparison using drag-and-drop functionality or using Add button. 
3. There will show up window with required name field for your comparison. Click Save button to create comparison.
4. Now you can add or remove features instantly, by moving them between grids. 

To adjust setting for currently selected comparison:

1. Change parameters on Settings form. Note that it works the same as the filtering in the Feature usage history page.
2. To update the both grid and graph, click Apply.

The option, "Show aggregated usage data on the graph", displays an extra line with the sum for all features (one each for total, average, borrowed and used licenses), as shown below.
