Edge Data displays the measurement results. In order to see the different results for multiple ROIs, choose the ROI you want to view the results of by clicking the name of that ROI in the Active ROI field. The results can then be examined below.
If you want to use measurement results in other documents, you can simply mark entries, use Ctrl+C to copy those entries to the global clipboard and subsequently paste them into any other document.
When you are satisfied with the measuring results, proceed to the Code Generation tab.
