Creating a Real-Time Plot Trend Chart

You create a real-time plot trend chart to display a variable in real time.

The real-time plot is a variable displayed directly in the trend chart. The real-time plot is an instant reflection of the variable, so the history of the real-time plot is lost when the trend chart is closed. However, the history is not lost for I/O points that have implicit logs where approximately 500 records of history are displayed.

A real-time plot trend chart updates and draws a solid series each time it registers that the variable has a new value. If the variable remains on the same value, the series is drawn as a dotted line.

When you save a real-time plot trend chart, a trend chart object is created that you can reach from the System Tree pane.

Nota
  • A real-time plot can only be displayed in a trend chart and not in a trend log list.
