 If the level of the tank is in the current range for the recipe, the graph can show the
level in yellow.
 If the level is higher than the level the recipe requires, the graph can show the level in
green.
Showing limits using scales with bar graphs
Unlike gauges, bar graphs do not have integrated scales.
Instead, you can show values on a bar graph using a scale and text. Scales consist of major
ticks, represented by long lines, and minor ticks, represented by short lines. To indicate
the values of major or minor ticks, use text objects.
Creating gauges
Use the Gauge tool to represent a numeric value using a needle on a dial.
In the Gauge Properties dialog box, specify the maximum and minimum values of the
gauge, and the tag or expression the gauge is connected to. For details about options in the
Properties dialog box, click Help.
At run time, the gauge indicates the value of the tag or expression in relation to the
gauge’s minimum and maximum values.
Creating bar graphs
Use the Bar Graph tool to create a graph that represents a numeric value by filling and
emptying as the value rises and falls.
In the Bar Graph Properties dialog box, specify the maximum and minimum values of the
bar graph, and the tag or expression the graph is connected to. For details about options in
the Properties dialog box, click Help.
At run time, the graph shows the value of the tag or expression in relation to the graph’s
minimum and maximum values.
Creating scales
Use the Scale tool to create a scale for a bar graph.
In the Scale Properties dialog box, specify the appearance of the scale. For details about
options in the Properties dialog box, click Help.
To place values on the scale as a legend, use text objects. Because the scale doesn’t
change at run time, you don’t need to connect it to a tag.
