Overlay Plots

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, and solid), the symbol that is used to plot each point, and the color of any item presented on the plot. You can select to plot only the connecting line and to fill the area under the lines or the area between the lines with a pattern, a color, or both.
This chart is a sample overlay plot showing the average and maximum number of concurrent TSO users by time of day.
