Stacked Areas

The Stacked areas option resembles the Lines option in that numerical values are represented as points, and the lines connecting them are diagonals.

The difference between the two options is apparent when the graph is in stacked or side-by-side format. In this case, multiple Stacked areas are created and the areas are stacked on top of each other, not overlaid. Thus, stack sections are exclusive of one another, and each is based at its lower boundary, not at zero.

Negative values are not possible for this graph type.

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. See "The Markers Options" later in this section ( Setting 2D Options).
