[Feature Request] Improve graph with more space for the important visual data

[Marzal]

Is your feature request related to a problem? Please describe. It's difficult to appreciate de temperature values when a day is really hot (all summer) and there is little variations between day and night. There is too much space wasted in the graph, and all the curves (data) are in a small zone. Describe the solution you'd like Don't start the graph at 0, instead start a the minimum temp less X

Describe alternatives you've considered Another option would be make it configurable

Additional context

Thanks for keeping alive this plasmoid
