The following example demonstrates a percentage stacked area chart.
We have already learned the basic configuration syntax of Highcharts in previous chapters. Next, let's look at other configurations. Add the `stacking` property in `plotOptions`:

## Configuration
### plotOptions: Data Point Options
`plotOptions` is used to set properties related to data points in the chart. The property settings for `plotOptions` vary slightly depending on the chart type.
Configure the chart stacking by setting `plotOptions.area.stacking` to `"percent"`. To disable stacking, use `null`.
var plotOptions = { area: { stacking: 'percent', lineColor: '#666666', lineWidth: 1, marker: { lineWidth: 1, lineColor: '#666666' } }};

$(document).ready(function() { var chart = { type: 'area' }; var title = { text: 'Historic and Estimated Worldwide Population Growth by Region' }; var subtitle = { text: 'Source: Wikipedia.org' }; var xAxis = { categories: ['1750', '1800', '1850', '1900', '1950', '1999', '2050'], tickmarkPlacement: 'on', title: { enabled: false } }; var yAxis = { title: { text: 'Billions' }, labels: { formatter: function () { return this.value / 1000; } } }; var tooltip = { shared: true, valueSuffix: ' millions' }; var plotOptions = { area: { stacking: 'percent', lineColor: '#666666', lineWidth: 1, marker: { lineWidth: 1, lineColor: '#666666' } } }; var credits = { enabled: false }; var 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] } ]; var json = {}; json.chart = chart; json.title = title; json.subtitle = subtitle; json.xAxis = xAxis; json.yAxis = yAxis; json.tooltip = tooltip; json.plotOptions = plotOptions; json.credits = credits; json.series = series; $('#container').highcharts(json); });
The output of the above example is:
