Creating Custom Runtime Displays
7 – 23
When the
Graph
viewport is displayed during run mode, the defined
variables are plotted from left to right; plotted variables are either line or dot
style (as defined), and the leading edges of the plotted variables are
emphasized by the “current position indicator,” a vertical line spanning the
viewport. During run mode, the current position indicator moves from left to
right as the variables are plotted from left to right (Note: The plotting of
variables cannot be observed during setup mode).
The basic steps for defining a
Graph
viewport are as follows:
•
Complete preliminary steps for defining a viewport. See “Initial Setup:
Selecting and Defining the Viewport,” near the beginning of this chapter,
for more information.
•
Select which of three variables (1, 2, or 3) you wish to define, using the
Next
or
Previous
box (located beneath the
Define Graph
box).
Remember that a variable is something that is tracked by the system, and
can be the result of a gage, a window, or a formula.
•
Using the
Define Graph Var.
menu, define the variable:
–
Enable the variable and set the graphing
Style
–
Line
or
Dot
.
–
Select the variable tool – the specific gage, window, or formula
number whose results will be tracked by the graph viewport.
–
Set the variable color (the color of the plotting in the
Graph
viewport
for the respective variable).
•
Using the
Define Graph
menu, define the
Event
, or circumstances under
which the graph variable plottings are updated, and set the
Upper
and
Lower
parameters for the range of the
Graph
viewport.
Selecting the Variable
You can define from one to three variables for the
Graph
viewport.
To select the variable you wish to define:
•
Pick the
Next
or
Previous
box (located beneath the
Define Variable
box).
