Shading
Use shading to show relationships between tags and to compare tag
values to constants. The figure below calls attention to tag values in
alarm. The difference between the tag’s value and the alarm’s level is
shaded.
Legend
Include a legend at the bottom of the trend to identify the data that is
being drawn by each pen. You can include some or all of the pens in
the legend, and can label each pen.
Control tags
Control tags are a type of memory tag—that is, they are tags that are
created and updated by RSView32
™ . You can use these tags to control
the view of the trend at runtime—for example, you can scroll and
zoom in on the trend.
