Highcharts: convert columns to stacked column in multiple axis chart

Question

I want to use combo-multiple-axis chart but i want to convert "columns" to "stacked columns" because one of my "y value serie" is the sum of 3 data series and i want to show that change on my chart too.

I am so new with javascript and coding but i guess there might be a way to add sub-data series to a primary data serie.

Answer 1

Just turn on stacking on the columns and then add multiple series of type column and this will just work.

plotOptions: {
    column: {
        stacking: 'normal'
    }
},
