A Percent Stacked Area Chart (also known as a 100% Stacked Area Chart) is a multi-series Area Chart that displays the trend of the percentage each value contributes over time or categories.
The concept of stacking in AnyChart is explained in this article: Stacked (Overview).
// create a chart var chart = chart.area(); // enable the percent stacking mode chart.yScale().stackMode("percent"); // create area series var series1 = chart.area(seriesData_1); var series2 = chart.area(seriesData_2);
The Area series' settings are mostly the same as other series'. The majority of information about adjusting series in AnyChart is given in the General Settings article.
