[Solved]-How do I calculate the sum of the points in a HighChart after I edit it-Highcharts

This should work for the Stacked bars:

var dataItem = chart.series[X].data[Y],
    dataValue = dataItem.percentage/100*dataItem.total;

for the line-graph, you should be able to do:

dataValue = dataItem.y;

See here:

$("#sum").text(series.data.reduce(function(a,b){
    return a + b.y;
},0));
