Area Graph

Display the elements in a variable as one or more curves and fill the area beneath each curve

Vectors create a single curve; matrices create one curve per column.

When the variable is a matrix, the curves are stacked to show the relative contribution of each corresponding row element to the total height of the curves at any x interval.

Plotted Variables

• Single variable -- plot a vector or each column of a matrix as one line vs. its index.
• Two variables -- plot the second variable in the sequence at the corresponding values of the first variable in the sequence.

• If the first variable is a vector, its length must equal the length of the second variable and it must be monotonic.

  If the first variable is a matrix, its size must equal the size of the second variable and each column must be monotonic.
