The problem

Hi,
I have a Tilt hydrometer integrated to Home Assistant that provides the specific gravity. Specfic gravity should be between roughly 1.000 and 1.100. The entity is correctly set up to have 3 decimals of precision and reports its state accordingly. However, when I want to look back and click the entity the graph in the more info screen does not accomodate for 3 decimals, only for 2 decimals worth of precision (it does not display inbetween values between let's say 1.01 and 1.02, it just swings back and forth). Interestingly, the history page works fine with this entity and you can see the difference between the two. (They were set to display the same amount of time and screenshotted right after each other).
First image shows the properties of the entity, second one shows the more info screen and third one shows the history page of the same entity. (Photos made on my iPhone, but the same on the PC as well)
I could make a template sensor to multiply the value, but in my opinion that is not the correct approach, just a workaround.
Thanks

#18312 fixes the plot to not round the datapoints. Ideally for a further enhancement still need to go back and fix the tooltip to respect the configured display precision though.
