Global

Command Button:

Command Path: Trend - Global

This is a command to set the global time-base. It allows you to toggle the Global setting on or off.

• If you have more than one Trend Window, you may set the Global option On to synchronise the time-base for all Trend Windows. This means that if you change the duration, or any time-base option, all the Trend Windows will change simultaneously.
• If you wish to set the duration, or time-base options for Trend windows individually then you must toggle the global option off.

Set

Command Button:

Command Path: Trend - Set

This opens the Set dialog box, which allows you to set the start time and duration for the Trend Line View:

• Trend field. This shows you which trend you are editing.

• Start time. This must be entered in the format HH:mm:ss.hh dd/mm/yyyy.

• Duration (trend view time span). This must be entered in the format HH:mm:ss.hh

• Options button. This brings up the Trend Options Dialog Box.

• OK button. Press this for the changes to take affect. Remember that if global time synchronisation is on changes made will be applied to all the trend pages.

• Press Cancel to abort the changes.
