Current behavior The pie chart only shows colour for each segment, would be great to present a percentage label within the segment. (like in #687)

What is the motivation / use case for changing the behavior? Better illustration

My children, please add this to your angular code to add percentages to the labelling:

setTimeout(function(){
    let labels = $('.pie-label');
    for (let label of labels){
      label.innerHTML += "%";
    }
}, 100)

It’s not ideal, but it works. You are welcome.
