Notes

The area between the data plot and the "From" Y axis value is filled for each data plot by default. When more than one data plots are plotted together in a layer, one might block each other. To plot an area graph stacked on the previous area graph (using the upper bounds of the previous area graph as the baseline of the next area graph), select Graph: Offset Grouped Data in Layer: Cumulative.
