12.3 Saving and Opening Trend Files
Use the File menu to save the trend data or load saved data for playback. For each device,
there is a trend window available and it is possible to open multiple trend windows for
multiple positioner devices at the same time. The trend window can be run while other
windows are active. Saving a trend does not discard current trend data, but you must
temporarily stop trending while performing the save.
To display a trend that has been saved, stop the current trend (save it if necessary) and
click File>Open. Then select the desired trend from the Open trend dialog. Click open. A
warning appears that all current trend data will be lost. Click yes to proceed or click no to
go back to save the current data.
