I have decided to keep the colour scheme that I had developed and also the visual explanation instead of statistical.
Because of this change, I have decided to add a 'Stats' page so that if users can understand the energy consumption by the statistics, they can also view them on a different page.
So there is no confusion about what the visual representation of the energy usage is of each appliance, there is a screen near the beginning of the startup of the interface, I have added a 'Key' to.
I have also added a settings option so the user can enter what four appliances they wish to observe and how bright they want the screen to be.
