Graph Setup
This option allows you to customize the graph
scale settings for each parameter. These settings
affect the high and low display limits for the Main
Screen bar graphs, Trend Graph display and the
graphs in the Summary and Tolerancing screens.
Radio buttons also allow separate settings for
Halfcycle, Segment and Weld displays.
Note: These graph settings are ‘global’ and used
for all IDs.
