A second display is superimposed on the SP graph to show the offset caused by the action
of the steam meter.
With no steam flow, the SP and control band will show a single display.
At 100% steam demand, the superimposed display will move up the column to the maximum
percentage set in the menu. The original SP will still be visible, to indicate the offset 2.
