area

Input Stack: expr: TimeSeriesExpr

⇨

Output Stack: StyleExpr

Change the line style to be an area plot. In this mode, the line will be filled from the data points to zero on the Y-axis, creating a solid area. For positive values, the area fills down to zero; for negative values, the area fills up to zero. This visualization is useful for showing volume, cumulative values, or when you want to emphasize the magnitude of the data.

Note

Multiple Series Behavior: When multiple time series are rendered as areas, their filled regions will overlap each other. To see cumulative contributions where each series builds on top of the previous ones, use :stack instead.

Parameters

• expr: A time series expression to render as an area plot
