The Many Gantt Chart Views

Did you know that Project ships 8 Gantt chart views?  I thought I'd take today to go into what each one displays.  To get to most of these views you'll need to go to the View menu - More Views dialog.

Gantt Chart - This is the plain Gantt chart.

Bar Rollup - If you like to rollup subtasks bars to the summary task, this view helps you with formatting.

    To roll a task up to a summary task, double-click the task to get to the task information dialog and check "Roll up Gantt bar to summary" on the General tab.  In this view you can then specify if you want the task name shown above or below the summary bar by using the Text Above column (only available in this view).


Detail Gantt - This shows the critical path, how far you have slipped, and how far you can slip before other tasks/the project finish date is affected.

    Red Bars - Critical tasks (tasks that must be completed on schedule for a project to finish on schedule)

    Black Line before a task - Slippage: This shows how far the task's start date has slipped compared to Baseline Start.

    Black Line after a task - Slack (specifically Free Slack): This shows the amount of time that a task can be delayed without causing its successor tasks to slip.  For a task without successors, free slack is the amount of time that the task can slip without delaying the finish date of the project. 

Leveling Gantt - This view shows you how leveling has affected your project.  (Wondering what leveling is - check out this help article)

    Green bars - Shows you where the bar was before the last time you leveled.

    White diamond with black outline - Shows you where the milestone was before the last time you leveled.

     Black line before a task - Delay: This helps to show you how leveling has caused a task to be delayed.  The line is drawn from Early Start (the earliest date that a task could possible being, based on early start dates of predecessor and successor tasks and other constraints) to Start.

    Black line after a task - Slack (specifically Free Slack): This shows the amount of time that a task can be delayed without causing its successor tasks to slip.  For a task without successors, free slack is the amount of time that the task can slip without delaying the finish date of the project. 


Milestone Date Rollup - When you roll up a milestone to the summary, this view displays the milestone name above the bar and the date below.  Regular tasks that are set to roll up will look like milestones on the summary bar.


Multiple Baselines Gantt - This view displays Baseline, Baseline 1, and Baseline 2.

Tracking Gantt - This is our second most popular Gantt chart and is best used when you want to see your critical path.

    Red Bars - Critical tasks (tasks that must be completed on schedule for a project to finish on schedule)

    Dark Gray bars - Baseline

    There is a bug in Project 2007 where regular tasks and regular task progress are both drawn with the same blue color and fill.  To fix this, when you are in the view, go to Format - Bar Styles and set either Task or Task Progress to have a different look.

Helpful tips:
While I don't want to get in to editing bar styles too much since that topic deserves its own post, I'll mention one helpful hint.  All the above views are customizable to meet your needs.  For example, in the Tracking Gantt, Baseline is displayed but say you want to compare Baseline 5.  To do this, just go Format - Bar Styles, and for the Baseline bar style set From to Baseline5 Start and To to Baseline5 Finish.  You can do this with other fields too.

Additionally, to quickly set a bunch of tasks to roll up/not roll up, insert the Rollup column.

  • I am very new at using Project.  Can you tell me how to enter an "if" statement for comparing dates.  Example: If a possible ship date is within 10 days of the due date how can I make the due date show up red.  Red indicating that we have 10 days or less to complete the task.  I am not sure if this is possible or not.  I appreciate your comments.  Thanks

  • Rather than editing and customising the built-in Views, it is much better housekeeping practice to leave the originals as they are and, with View, More Views etc, copy one which is close to what you want, give it a distinctive name such as "AA my special view #1" and then customise this new copy. I put the "AA.." in the name so that the new view goes to the top of the list in the View menu and so I can always distinguish between the ones I have made and the originals.

  • Is it possible to not show dates on the Gantt chart?  Instead of a date as a start date, I want to have the start date as Day 1 and then count from there.

  • Gertrude - Are you referring to the timescale at the top of the view?  If so, what you are asking is possible.  To do this, while in the Gantt chart view, go to Format - Timescale.  On the tab which defines what days look like (probably bottom tier), set Label to 128 (Day of Year) if you want the days to be numbered numerically starting on Jan. 1st.  If you want the first day of the project plan to be day 1, select Day 1, Day2 (from start)

  • Hi there,

    is it possible to somehow change the appearance of the bar start and bar end styles apart from the existing ones. Meaning, is it possible to probably patch some dll or something to change the default styles.

    I wish to enumerate my milestone "1", "2", etc instead of using some provided abitrary icons.

  • We don't support adding new shapes for bar styles.  You could, in addition to the icon, show a number by using a custom field and updating the milestone bar style.

    To do this, first in a custom field, number your milestones however you want to.  Then in the Gantt chart view, go to Bar Styles, select Milestone, and in the second part of the dialog go to the Text tab.  Here you can set the custom field to appear next to the icon.

  • hi

    i have rolled-up my milestones to the summary task. i have aslo added text to the rolled-up milestoones. but now i want to apply different text formating for different rolled-up milestones. i.e for one rolled-up milestone i want different text fon, font size and color.

    is it possible to do? if yes how can i do this?

  • I have some milestones in  my project which i have rolled-up to the summary

    bar. i have added text to my rolled-up milestones, but what i want is to

    change the text font and color only for one or some of them, not for all to differentiate them from each others.

    thanks in advance

  • This is kind of possible to do.  You can change the look of individual milestones but all the text will look the same if you are using the same style.

    To change the look of individual milestones, just double-click on the rolled up one you want to change and in the format bar dialog set the custom formatting.

    To change text, you'd have to change the entire text style through the text styles dialog.  We have a separate style for each bar text (top, bottom, left, right, inside).  So if you want a different look you'd have to put the text in a different place.

  • Thanks for the answer.

    but i have tried all these. what i want is to set the individual text color for all individual rolled-up milestones.

    but i think it is not possible, is it?

  • Nope, that isn't possible.  Your only option would be to have the text look the same and change the color/look of the milestone shape.

  • hi

    on the format menu there is an option for Text Style. in that against Item To Change, there is highlighted tasks and marked tasks.

    what are highlighted tasks and marked tasks?

    please explain me

    Thanks for listening my doubts

  • I am very new to Project 2007 and I looked at some templates from the website and a couple of them had Gantt Charts with labeled bars which made the presentation look neater and easier to understand - exactly how may I replicate this?

  • Can you explain how project plans can be printed from within project server, not using project professional.  I would like to know if Gantt charts can be printed?

  • Maria - to label bars you need to edit the bar or bar style. Editing the bar will only affect the selected task while editing the bar style will affect the entire project. Then in the Bar or Bar Styles dialog, set the bottom section to text (by default the selected tab is Bars which let's you update the look of the bar). The text setting let's you then display text fields on all sides of the bar and inside the bar.

    Myron - You can't print gantt charts from Project Server but you can print the grid-side. To do this, go to Project Center and click on the project you want to print. This will take you to the project drilldown. Now from the Actions menu, select Print Grid. This will open a new window where you are able to print the grid from.
