SpreadJS supports area, stacked area and 100% stacked area charts. Use the GC.Spread.Sheets.Charts.ChartType.area property to get the chart type.
You can add an area chart to Spread and change its style using the chart API.
Area: Area charts show trends over time.
Stacked Area: Stacked area charts show the trend of the contribution of each value over time or other categorical data.
100% Stacked Area: One-hundred percent stacked area charts show the trend of the percentage that each value contributes over time or other categorical data.
