Configuring shading
Use shading to compare the values of different pens. To have shading,
at least two pens must be defined.
For the upper and lower boundaries, select the pens with which to
compare values. When the pen you are defining plots above the value
of an upper boundary pen, or below the value of a lower boundary
pen, the area between the pen you are defining and the boundary pen
will be shaded. The shading color will be the color you select under
Style.
Shading is determined by the position of lines on the screen—not by
the actual tag values—because each tag has its own vertical axis.
This is important if you have specified different minimum and
maximum values for the pens.
