Hi Nick,
Insert a Flag field into the table (for example: Flag1). Right click on
the column heading and choose Customize Fields from the shortcut menu.
Click the Formula button and enter the following:
IIf[Finish]>[Baseline Finish],1,0)
This will change the Flag field to "yes" for tasks for tasks that the
finish is greater than the planned finish (baseline finish)
To change the Gantt Bars:
Go to Format > Bar Styles. Insert 1 blank under the Tasks line
New line:
Name: LateTasks
Appearance: whatever you choose
Show for: Flag1
Row: 1
From: Start
To: Finish
As far as showing the text for the "late tasks" in a different font or
font color, you could manually change the [Marked] field to "yes" and
then use Format > Text Styles to change the format of Marked tasks.
I hope this helps. Let us know how you get along.
Julie
