RE: micrsoft project
Hi Edward
You can make basic changes to the Legend by going to file > page setup > legend (this lets you turn the legend off or on for example)
If you want to control what appears in the legend you need to goto Format > Bar Styles. This is where the formatting rules for Project are stored. Each item listed will appear in the Legend. Changing the formats here controls both the way the item will appear in your project and also how that item will apear in the Legend (make a backup of your Project before making changes). If there is a format that you want to keep in your Project but not have it displayed in the Legend modify its name so it begins with an asterisk (e.g. *Rolled Up Task).
I hope this is helpful - let us know if you have any further questions.
Kind regards,
Andrew
