I have added trend buttons to the FMCS Overview MEDM which open MEDM screens showing the most recent 1day, 1week, 1month trend plots.
Attachment shows the Overview and the VEA temperature trends, showing the recent MY drop in temperature.
Did the same for the Vacuum Trends, they can be launched from the Vacuum Overview MEDM using a pull down related display button (located bottom-right of screen).
