The Shaded areas option draws exactly the same display as the Lines option, except that the region under a line is shaded.
When the 2D graph is in stacked or side-by-side format, multiple Shaded areas are created. These areas are overlaid: the region under a given line is based at zero. Thus regions for lower values are shaded both by their own colors and by the colors shading higher values.
Negative values are allowed for this graph type.
When the 2D graph is neither stacked nor side-by-side, the Shaded areas graph is exactly the same as the Stacked areas graph.
Select Options® 2D options to call up the 2D Options dialog window and choose the graph type.
You can mark the data points with small circular markers using the Markers options und Other Options.
