Trend Cursor Does Not Appear
If the trend is part of a display, select it. If that doesn't enable the Trend
Cursor (page 120), the trend is probably too small. Double-click to make
the trend larger.
Trend Legend Does Not Appear
Make the trend larger. If that doesn't help, check the default Trend Format
settings.
Cannot Change or Save a Display
If your FactoryTalk Historian ProcessBook is part of a View-only
installation, you are unable to save any ad hoc trends or alter displays or
ProcessBooks.
If you cannot alter a display or ProcessBook, you may be in either View
mode or Run mode. If you are in View mode, you have only one toolbar.
If you are in Run mode, the Run mode button on the Drawing toolbar
is depressed. Switch to Build mode .
