In NPM when you go to view a graph of performance data there is a button labeled "Chart Data" right next to the button that allows you to export the data to Excel.
I think it would be nice to have this button with APM graphs as well. It may seem overly simple but it's fast, gets you the data you need quickly and doesn't require Excel (or any other spreadsheet program). In addition, it would be a step toward making APM have a more consistent feel with NPM.
Thoughts?
