ShowHistoricLines Wizard option

The Boolean value of ShowHistoricLines shows or hides cached variables over a 30 second interval collected at 10, 20, and 30 seconds. The chart symbol shows the current and the cached variable lines. The 30 interval repeats and updates the cached variable lines continuously during run time. The default value is False.
