PieChart with value lines with very small values render values on top of each other

[luiseduardoglez]

What did you do?

Created a pie chart with value lines to display de values outside the chart. Some of the values i'm getting now are very low (0.5%, 1.5%)

What did you expect to happen?

Draw a pie chart with values.

What happened instead?

The two values that are very low can't be understood as they render on top of each other. As it's visual i let you a screenshoot of how the chart renders

it seems unavoidable? just like bar chart values, similar value lead to similar position.
