That would be a lovely thing, instead of the rather cheesy coffe cup circa 1980 on Windows...
I created this custom function, may be it will be useful:
Bars ( CurrentValue , MaxValue , BarCount ) =
Case ( CurrentValue > 0 and MaxValue > 0 and CurrentValue ≤ MaxValue ; Repeat ( "I" ; ( CurrentValue / MaxValue ) * BarCount ) )
I agree. ;-)
