Ability to set maximum decimal places in charts

[ivanELEC]

Is your feature request related to a problem? Please describe.
I want to have a pie chart that shows percentages to the nearest 2 decimal places. As it stands, I can set the visualisation to have a minimum number of decimal places - but there's no clear way to set a maximum, the shown number of decimal places depends purely on the size of the chart.

Describe the solution you'd like
I would like a setting in the visualisation settings of any chart to specify the max number of decimal places alongside the other style settings

Describe alternatives you've considered
I cannot think of other alternatives for this
