Shifting an Analog Pen's Scale Range on the Graph

When you are plotting data for analog tags, you wish to shift the position of one or all of the pens on the display.  Examples include:

•    Shifting a pen so that it does not interfere with the view of another pen.

•    Shifting a pen so that it overlays another pen for comparison purposes.

•    Shifting one or all of all the pens so that they are in the middle of the graph rather than at the edge.

Note that only analog pens can be shifted. This topic does not apply to digital pens.

The Shift Y-Axis button looks like so:    To use it, follow these instructions:

1.   Decide whether to shift one pen or all pens

•   If one pen, select that pen in the legend.

•   If all pens, select no pens in the legend.

2.   Click on the Shift Y-Axis button.

3.   Click on the graph and, while holding the left mouse button down, drag the pen display up or down.
