components by using the cursor to click and drag a bounding box around the
desired components. The components can also be selected by selecting the
first component and then selecting the other components while holding down
the <ctrl> key. The last component is identified by dark blue handles and by
dark blue highlighting in the Project Tree. The other selected components
have handles with blue outlines and are highlighted in light blue in the Project
Tree.
Center will center the selected component(s) either vertically or horizontally
on the page.
Order is used to manage the position of graphic objects on the workspace.
Displays are often a combination of a background graphic and data display
objects in front. Objects added to the workspace are, by default, placed on top
of any existing objects. These operations are used to determine the order in
which objects are displayed.
Group Components allows you to group components together. They can then
be moved, copied, ordered, etc. as a single object. Select the components to be
grouped by holding the Ctrl key and clicking the components with the primary
mouse button. Then choose the Group Components item from the Component
menu or the Component right-click menu. You must have at least two
components selected for this menu item to be enabled.
When a component group is selected, the menu item will change to Ungroup
Components. You can undo the component grouping by selecting this menu
item.
When components are grouped, the properties for each of the components will
show up as an item in the Component right-click menu. These menu items can
be used to modify the properties for each component.

detailed descriptions of all of the display properties and operations. The Index
allows you to look up help topics based on a key word.
8.1.5 Expressions
Components that display data values either numerically or graphically can be
processed using expressions. These expressions can include simple
mathematical expressions, functions to manipulate strings, or more complex
functions that deal with the state of a data value over time.
For instance, a temperature reading in degrees Celsius can be processed to
display in degrees Fahrenheit using a simple mathematical expression. This is
done by first selecting the data value in the
Select Data field, and then entering
