Overlay F/V Loops
The Overlay F/V Loop screen consists of a single F/V graphical display of the best FVC
loop from each trended session, a chart showing the trended plots, and a tabular grid
showing the parameters trended.
Overlay Screen
The F/V loops are displayed in up to ten different colors. If the number of F/V loops
exceeds ten, the control reuses colors. The same color scheme is used in the grid control,
showing the session number and report date in the color that matches the associated F/V
loop.
When you move the vertical marker to a date or select a point in the grid, the software
highlights the F/V loop corresponding to that report (if one exists) by drawing the loop in
a darker color. The loop returns to its previous color when you select another report.
