What is the value of the activity chart?

The fitness report is dominated by an activity chart, which seems to indicate how much time I spent entering data into Gyminee. This seems to be of very limited value fow my fitness goals and always skewed toward food entry as I have th enter a lot more items. Unless I am burning calories or burning muscle while typing. :) Am I missing some secret value? Ideal would be selecting a graph of ones choice, but barring that there must be some more interesting fitness oriented information to display. It seems to be of such limited use that removing it to reduce scrolling to see the rest of the information might even be a better choice.
