[FEATURE] Maximum graph button should also remove tinted prediction in the background, not only line

[Pkawa]

Is your feature request related to a problem? Please describe.
In previous version I always turned off maximum turnip value, because it messes up the chart. Line chart was then redrawn on the screen, allowing me to clearly see how my price stands up to average/min price prediction.
Maximum due to its nature just completely flattens the image. New calculator version has that maximum price tint that does not go away when it is turned off. Maximum button removes only the line.

Describe the solution you'd like
Please either:

1. Make maximum button also remove background color prediction when disabled
2. Add another option while pressing repeatedly maximum button. It doesn't have to be binary after all - there might be option to show line and tint, only tint and to have both of them disabled.
