Nightscout has reports, one of which is daily view of the graphs. Here’s an example of a daily graph from when I actually bothered to input all my treatment decisions 
I do find it helpful to see the treatment decisions there together with my CGM trace, but it does require a lot of commitment to get the amount of data necessary for it to be helpful. At this point I typically only enter stuff in if I have something I’m trying to troubleshoot or experiment with. When I was first trying to get my act together I did it for a few months straight.
