You can control the fill color to use for your
objects.
To configure an object or group with
changing fill color:
Draw the object/group (or paste a
symbol). The properties tab dialog will automatically display,
unless you have turned off the Display properties
on new option in the Graphics Builder. (For a group, the
properties dialog will not display automatically; you need to
double-click the group.)
Click the Fill tab.
Click the Color tab (to the right of the dialog).
Select the type of color change
(On/Off, Multi-state and so on).
Enter the expression/conditions
that will change the object's fill color at runtime.
Enter additional object property
details as necessary.
