Bar Graphs
This chapter tells you:
•
how bar graphs function
•
how to configure bar graphs
Bar graphs are useful for monitoring analog conditions that change,
such as temperature or fluid levels. You can create vertical and
horizontal bar graphs across the height or width of the screen.
Vertical bars can be configured to fill from bottom to top or
vice-versa. Horizontal bars can be configured to fill from left to right
or vice versa.
Tip: Use the following suggestions to customize bar graphs:
•
To show the bar’s fill level, make an axis with incremental ticks
alongside the bar graph by using the Scale object, or by using
lines or graphic images.
•
To have a bar graph change color at certain values, cascade bar
graphs together. To do this, remove the border from the graphs,
place the high end of one graph at the low end of the next, and
adjust each graph’s data range accordingly. To add a border to the
cascading graphs, place a hollow or solid panel behind the bar
graphs.
•
To create a fully functional “template,” group bar graphs with
other objects. For example, position two or three bar graphs
together and put numeric display objects immediately below the
bar graphs to display the process variable, set point, and control
variable. You can use any of the numeric entry objects
interactively with these values.
