StackedListPlot

StackedListPlot[{data1, data2, ...}] plots lines for each of the datai, with the ith curve being the accumulation of values in data1 through datai.

Examples

Create a stacked list plot:

StackedListPlot[{Range[10], Range[10, 1, -1], Table[5, 10]}]

With filling:

StackedListPlot[{Range[5], Range[5, 1, -1]}, Filling -> Axis]
