Precipitation probability type incorrectly represented on the canvas graph

[dbustosrc]

Is your feature request related to a problem? Please describe.
The probability of rain represented on the graph is presented incorrectly, for example. At 55% probability it shows a full bar as if it were 100% instead of a half bar closer to 50% because it is the maximum probability taken and from there it calculates the rest down 48%, 40%, and 17%

Describe the solution you'd like
The sample should always be graphed from 100% down, and not take the maximum probability as 100% in the sample

Additional context
Edited screenshot of what the graph should look like:

precipitation_type setting is removed and replaced by show_probability setting. show_probability will show the probability next to the rainfall. The bars will show the rainfall with from 20mm as full for day and from 4mm as full for hour view.
