Stiff diagrams are discussed in many ground water references, including Zaporozec (1972).

The Stiff diagram displays a comparison of concentrations for six different parameters. Concentrations are plotted on the four corners of a box, and the midpoints of the left and right sides of the box. The Stiff diagram has the following characteristics:

• One graph is produced for each sample collection date/location ID combination. If there are multiple containers for a date/location pair, the diagram will display one plot for each container to a maximum of five.
• The bottom right portion of the diagram can be displayed with a scaled axis. Various axis options are available for the graph.
• You can use field names to specify custom graph titles and axis labels.
• Any units listed from Options | Units, as well as meq/l are available for the plot.
