Currently I have a stacked bar chart like this (jsfiddle demo)

I want to change the stacks so that each bar is converted to to a % of the total stack height. For example, in the Apples stack we currently have {3, 2, 5} for a total of 10.
Instead, I want to show {30%, 20%, 50%}. Of course, I could simply do the conversion myself before passing the data to HighCharts, but I want to still show the raw numbers {3, 2, 5} as the bar labels (in red above).
Simply change the
plotOptions.column.stackingproperty topercent.Check more information and demos in the HighCharts’
plotOptions.column.stackingdocumentation.
