Figure 3-13.  Sample Overlay Plot

Overlay plots are multiple plots (for example, y against x
and z against x) on a single axis and scale.  Up to four
variables can be plotted against a fifth variable.  Use
overlay plots to illustrate the relationships among multiple
variables that are influenced by a single independent
measure.

You can control the chart axis scale, data element labels,
and printed value formats.

With printer graphics, only the points of the graph are
plotted; they are NOT connected by lines.

With color graphics, you can leave the points unconnected or
you can connect the points with straight lines, a smooth
curve, or a step function.  You can specify the format of
these lines (for example, dotted, solid, etc.), the symbol
used to plot each point, and the color of any item presented
on the plot.  You can choose to plot only the connecting line
and/or to fill the area under the lines or the area between
the lines with a pattern, a color, or both.

Figure 3-13 is a sample overlay plot showing the average and
maximum number of concurrent TSO users by time of day.
