3.4 DISPLAY MODES (Cont.)
3.4.3 Vertical bargraph
Note: If the Circular Trend option is fitted (
), the Circular Trend display mode replaces the
Vertical Bargraph mode. In such a case, Vertical Bargraph does not appear in the Views configuration menu,
in the GoTo View menu or in the down arrow scroll list, but is available to user screens if the relevant option
is fitted. (See section 2 of the Options Manual for a description of User screens.)
Entered from Horizontal Trend mode by means of the down arrow key, or selected from the
'Goto View'
key, this display mode shows the Process Variable (PV) values as vertical bars with faceplates containing digital val-
ues and alarm data. There are two versions, one with faceplates above the bars (1 to 6 channels - figure 3.4.3a); the
other (with faceplates at the right hand edge of the display - figure 3.4.3b) is used where there are more than six chan-
nels.
Note: The description above refers to the 180 mm version of the recorder. For the 100 mm version, the
faceplates appear above the bars for one or two points, but to the right of the bars for three or more points.
Operation of the option key calls the Option menu display for this display page, allowing faceplates to be selected on
or off. This feature is available for vertical trend and vertical bargraph displays only.
To call the horizontal bargraph display mode, use the down arrow key. Alternatively, any one of the enabled display
modes (
, 'Goto View' key.
Trend history mode is not available from this display mode.
FACEPLATES ABOVE THE BARS
See figure 3.4.3a.
As the number of channels in the display group increases, the bars and their faceplates get narrower,
FACEPLATES AT RIGHT-HAND EDGE
See figure 3.4.3b.
As the number of PVs increases, the bars get narrower. As the bars get narrower, so the scale values become trun-
cated as shown in figure 3.4.3b. The bars have a set minimum width, and if the total number of points in the group
cannot be displayed within the width of the screen, a horizontal scroll bar appears, allowing 'hidden' bars to be
viewed. Similarly, the faceplates reduce in height to a minimum readable height. If there are more point faceplates
than can be accommodated within the height of the screen, a vertical scroll bar appears, allowing hidden faceplates to
be displayed as required.
