It would be good as the user to be able to set the range of the vertical axis. Currently when you scroll between screens to compare usage across months the range of the vertical axis jumps around to fit the data. So the changes in usage aren't so obvious. One months peak of 60 kWh hours looks the same as the next months peak of 30 kWh for example because they both jump up to the top of the screen. Thanks Michael EDITED: This just relates to the website. Not sure about the app.
