Figure 1. An example of reference distribution for serum lactate dehydrogenase (U/l) in 254 healthy reference subjects. The figures in the upper right corner show the X- and percentile values of the cursor. These will update instantaneously for any cursor position. In the left-sided data window the reference distribution is given in numbers. Sizes of the windows can be adjusted. Defined reference limits (vertical lines) with the corresponding confidence limits (broken vertical lines) can optionally be shown in the graph.

Figure 2. The same distribution as above after optimization of the bin width for illustrative display. Note that the cursor has also been moved to a new location. Windows clipboard (Edit Copy and Edit Paste commands) can be used for copying both the graphs and numeric data from GraphROC into other Windows applications.
