With Motion we have a large number of metrics you can use to build your reports! If there is are metrics you'd like to add into your reports, which are not showing up when adding them into the graph, here is what you can do.
Head to the bottom table chart, and select the 'Custom' button.
In the top bar, search for the desired metric
Check any metrics you'd like to add into the table chart (the columns below the graph)
Once the metric is added into your table of metrics, you should now be able to search for that in the graph above
