Highstock, dynamically changing from percent stacking to normal stacking - highcharts

Question

Like the title says, if you have a chart with percent stacking enabled for each series and then try to change to normal stacking using the series.update() method it does not work. It doesn't seem to do anything.
percent to normal example: http://jsfiddle.net/8tbPD/
The reverse does work though.

Is there something I'm missing?
Thanks.
$('button').on('click', function() {
for(var index in chart.series) {
chart.series[index].update({stacking:'normal'});
}
});

Answer 1

Unfortunately you need to destroy and create a new chart.

Basically, add a series with "stacking" but with no data. Then show and hide that series (whose stacking-attribute will affect all other series) using JavaScript, e.g. button.
$(function() {
$('#container').highcharts({
chart: {
type: 'area'
},
title: {
text: 'Historic and Estimated Worldwide Population Distribution by Region'
},
subtitle: {
text: 'Source: Wikipedia.org'
},
xAxis: {
categories: ['1750', '1800', '1850', '1900', '1950', '1999', '2050'],
tickmarkPlacement: 'on',
title: {
enabled: false
}
},
yAxis: {
title: {
text: 'Percent'
}
},
tooltip: {
pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.percentage:.1f}%</b> ({point.y:,.0f} millions)<br/>',
shared: true
},
plotOptions: {
area: {
stacking: 'normal',
lineColor: '#ffffff',
lineWidth: 1,
marker: {
lineWidth: 1,
lineColor: '#ffffff'
}
}
},
series: [{
name: 'Asia',
data: [502, 635, 809, 947, 1402, 3634, 5268]
}, {
name: 'Africa',
data: [106, 107, 111, 133, 221, 767, 1766]
}, {
name: 'Europe',
data: [163, 203, 276, 408, 547, 729, 628]
}, {
name: 'America',
data: [18, 31, 54, 156, 339, 818, 1201]
}, {
name: 'Oceania',
data: [2, 2, 2, 6, 13, 30, 46]
}, {
showInLegend: false,
stacking: 'percent'
}]
});
// the button action
var chart = $('#container').highcharts(),
$button = $('#button');
$button.click(function() {
var series = chart.series[5];
if (series.visible) {
series.hide();
$button.html('Percent');
} else {
series.show();
$button.html('Normal');
}
});
});
