I currently have a stacked bar chart similar to the one shown in this JSFiddle demo.
My goal is to transform the stacks so that each bar represents a percentage of the total stack height. For instance, in the Apples stack we currently have values {3, 2, 5} totaling 10.
What I aim for is to display percentages like {30%, 20%, 50%}. While I could easily calculate these percentages before providing the data to HighCharts, I still want to exhibit the original numbers {3, 2, 5} as the bar labels (highlighted in red above).
