Control

Control:

Purpose:

Interval

A pre-configured list of durations to specify the X axis time display. Defined in minutes (m), hours (H), days (D), weeks (W) and months (M)

Params

This controls the way pens are added via the /QuickTrendPens command line qualifier.

If at startup, a file is specified using /QuickTrendPens=<file> option, the system will monitor this file for any subsequent changes.

After a change, the new items specified in the file will be incorporated into the plot depending on the Params setting:
 

• Single
  All other pens will be removed and the new pen will be displayed on  its own.
   

• All
  If the specified item ends with .PV, .SP or .OP then the plot will attempt to display three pens (if they exist), with all three suffixes substituted. For example: specifying CAF101.OP will display CAF101.PV, CAF101.SP and CAF101.OP.

If the item does not end with any of these suffixes then the plot will behave in "single" mode and load only that item.
 

Tip:  The color of the .PV, .SP and .OP pens can be controlled in the "/QuickTrendConfig" file.

Note: The “ALL” mode is for only one item, not multiple. By definition, if Pens File has more than one item, it is in MULTI mode. The default mode will be ignored in this case.

• Multi
  Any new pen introduced in the "/QuickTrendPens" file will be added to the display after the others.

Style

The Stack checkbox will toggle to display between displaying each pen stacked in a separate region - one on top of the other, or superimposing pens over each other in the same area.

The Locked checkbox is enabled when stQuickTrend is started specifying a Pens file via the command line.  Checking the Locked option prevents changes to the Pens file from updating the pens list for the plot.  

Tip: This can be useful when trouble shooting allowing the operator to lock down the current trend tag set to aid with troubleshooting / unit monitoring.

Left Right / Buttons

Pan the display backwards or forwards in time.
