A Vertical Spline Area Chart is a simple Spline Area Chart with its categories spread among the vertical axis. The difference between Spline Area Chart and Area Chart is that points and angles are replaced with a single spline.
Find how to create a Spline Area Chart in the following article: Spline Area Chart.
// create a vertical area chart var chart = chart.verticalArea(); // create splineArea series var series1 = chart.splineArea(seriesData_1); var series2 = chart.splineArea(seriesData_2);
The Vertical Spline Area series' settings are mostly the same as Area series' settings. The majority of information about adjusting series in AnyChart is given in the General Settings article.
