On the ArcGIS Developers site, you can click the View Usage button on any Geocoding API you have created. By default the only option for the Y-Axis in the Usage chart is the total geocode requests. This idea would be to add an option to change the units of that axis to Geocoding credits to make it easier to compare usage of individual geocoding APIs with the overall credit utilization (measured in geocoding credits) shown in ArcGIS Online.
