Great. Works instantly. Also adds a "switch graph" button that conveniently allows you to switch between the standard Garmin graph, and the colored one. THANK YOU. Note that, as of Sept 2022, it's not possible to peek, or zoom in, on the "colored" graph. UPDATE: It works for running activities, great. It doesn't seem to work for swimming, unfortunately.

it does exactly what I expected as shown in the example. I didn't even think that such a thing could be done. Came here while searching the Garmin forums for a field as an add on to the watch that would do the same thing. :-)
