Is your feature request related to a problem? Please describe.
This isn't a problem, but it would be a convenience.
Added the ability to use the entity state as the max value, using series for the radialBar type.

Describe the solution you'd like

max: '{{ states("sensor.somesensor")}}'

or

max: sensor.somesensor

Describe alternatives you've considered
I don't see any other way to assign a dynamic value here

Additional context
In this case, it is about defining the maximum value for the daily consumption of limited mobile data - this is calculated in the entity template
