Datum Lines

Datum Lines

Datum lines can be added to graphs to show limits and reference curves. Unlike normal curves DATUM lines are not used to calculate graph limits when auto scaling and are not shown in the curve legend. There is no hard-wired upper limit on the number of datum lines - machine specifications are the limiting factor.

Each graph can contain multiple DATUM lines, all DATUM lines are drawn in the order they have been defined before any curves are plotted.
