Change the Trend configuration at runtime

lIf the Enable runtime configuration option is selected from the PenTrend Control dialog box, operators can change some characteristics of a 16-Pen Trend while the application is running.

Run-time changes to the 16-Pen Trend are not permanent. If operators close WindowViewer and then start the application window again, the 16-Pen Trend retains the configuration originally defined from WindowMaker. The following figure shows the PenTrend Control dialog box that appears if you select on a 16-Pen Trend while it is running.

You can change the following during run time:

• Tags or expressions assigned to trend pens

• Characteristics of trend tags or expressions

• Type of trend (Historical or Realtime)

• Date and time range of a historical trend

  

• Update rate and frequency of a real-time trend.

  

After clicking Done, the trend retains the configuration changes for the duration of the current WindowViewer application session.
