Radial chart legend percentages

[tonidalmases]

Bug Report

Expected Behavior

When using the radial chart with percentages, without Max value (full chart), the sum of percentages in the legend should be equal to 100%.

Current Behavior

In some occasions, the sum is not equal to 100, since the chart does not consider a precision, nor rounded percentages.

The current behavior (the sum is equal to 99.98)

Possible Solution

Adding precision to the chart would fix the number of decimals to display in the legend.

However, note that the sum would be equal to 99.9, since those percentages are not rounded to 100. A possible implementation, described Here, would also solve the issue by distributing the percentages in a way that the final result is equal to 100.

Steps to Reproduce

Issue also described in APM-277510.

This issue is extensive to all kind of charts in barista whose percentages must sum up 100%.
