The Simple Vertical Bar primitive allows an expression to be drawn as a vertical
bar-graph between specified limits. Additional properties allow the primitive’s
fill color and border style be defined.
The Simple Horizontal Bar primitive allows an expression to be drawn as a
horizontal bar-graph between specified limits. Additional properties allow the
primitive’s fill color and border style be defined.
The properties are accessed by double-clicking the primitive…
• The Value property is used to specify the value to be displayed. In the example
given above, the primitive is configured to display the level of a tank.
• The Minimum and Maximum properties are used to specify the range of values to
be shown. In the example above, a range of 0 to 100 is specified.
• The Fill Format properties are used to define the fill color for the primitive. The
filled area of the bar is drawn in the pattern and colors indicated, while the
unfilled area is drawn with solid Fill Color 2.
• The Line Format properties are used to define the border for the primitive.

The Vertical Bar Graph primitive displays a set of values from an array as a
number of vertical bars. Each value is scaled according to the same minimum and
maximum values. Between 2 and 400 values can be shown.
The Horizontal Bar Graph primitive displays a set of values from an array as a
number of horizontal bars. Each value is scaled according to the same minimum
and maximum values. Between 2 and 400 values can be shown.
