The Rich Vertical Bar primitive allows you to display a more complex bar-graph
which includes a label, a numeric version of the data being displayed, and tick
markers to indicate any associated setpoint.
The Rich Horizontal Bar primitive allows you to display a more complex bar-
graph which includes a label, a numeric version of the data being displayed, and
tick markers to indicate any associated setpoint.
The operation of these rich primitives is analogous to that of the various tag text primitives, in
that they are capable of deriving much of the required formatting information from the tag
used as their controlling value. Just as with tag text primitives, multiple tabbed pages are used
to edit the primitives’ properties. The first of these pages is shown below…
• The Value property is used to define the value to be displayed.
• The Show Label property is used to indicate whether a label should be included
with the bar-graph. For vertical graphs, the label is included at the bottom; for
horizontal graphs, it is included at the left-hand side. If a tag is used for the value
property, the label may be obtained from that tag. Otherwise, it must be entered
on the Format tab of the dialog box.
• The Show Value property is used to indicate whether the value of the data should
be displayed within the graph itself. If a tag of the appropriate data type is used
for the value property, the format may be obtained from the tag. Otherwise, as
with the label, it must be entered on the Format tab.
• The Show Setpoint property is used to indicate whether tick marks should be
added either side of the bar to indicate the setpoint for the controlling value. This
option is only available if a tag has been entered for the value field.
