On Firday, we proposed a new chart for showing project plans. I chose an ugly name for it and called it Gantt Box Chart.
Essentially, a gantt box chart is what you get when a gantt chart and box plot go to a bar, get drunk and decide to make out. It shows the project plan like any other gantt chart, and it shows the distribution of activity end dates, like any other box plot.
You can see an example gantt box chart for a fictional software project above.
Today, we will learn how to create a similar chart in Excel. Get a steaming cup of coffee or whatever keeps you going and follow these simple steps to make a gantt box chart.
[Read this post if you want to know what GBC is and how to read it]
1. Set up your data:
Just like any other chart in excel, a gantt box chart too requires well structured data. In our case, we need 5 things.
- Activity name
- Start Date
- Best Case End Date
- Realistic (or Plan) End Date
- Worst Case End Date
Getting all the 3 variations of End dates can be tricky. But if you are managing projects for long, you might already know how to get these dates. Otherwise, here is one approach, proposed by Joel Spolsky, called as Evidence Based Scheduling that can help you.
We will also need 3 additional helper columns where we need to calculate some numbers so that our gantt box chart can be constructed without resorting to magic wands. These are,
- BC: Number of days between Start Date and Best Case End Date
- R: Number of days between Best Case End Date and Realistic Date
- W: Number of days between Realistic Date and Worst Case End Date
2. Create a Stacked Bar Chart
Add a new stacked bar chart. The series to be stacked are,
- Best case end date
- R
- W
Use the “Activity Name” column for category axis labels.
Now, our chart should look like:
3. Say your favorite curse word and Reverse the categories
Ok, time for a minor annoyance. Excel has magically showed the first activity of project at bottom. So, we need to reverse the category axis values before any further.
Just select the category axis, go to format axis (press CTRL+1) and click the little box that says “order reverse in Categories”.
Now, the chart should look like this:
4. Add Error Bars to Best Case Series
Now, add error bars to the best case series of the chart so that it looks like a line is drawn connecting best case date to start date of each activity. To do that, follow these steps:
- Select “best case end date” series.
- Add Error Bars (from format ribbon)
- Specify the type of error bar as “Negative only”
- Select “Custom” for error bar values
- Now, point the error bar values to the helper column “BC”
- Format the error bar in such a way that no cap is shown and it is thick.
At this point, our gantt box chart should look like this:
5. Finally, format the chart
Now, our gantt box chart is almost ready. But it is still ugly. We need not hire a Hollywood grade make-up man to beautify this. We just need a few clicks.
- Remove legend
- Add vertical and horizontal grid lines. Make them subtle.
- Change text colors to soothing ones.
- Remove fills from all series in stacked bar chart.
- Apply borders to 2nd and 3rd series to create a box effect.
- Format the date axis,
- Adjust the starting point (unfortunately you have to enter the number equivalent of date, like 1-May-2010 as 40299)
- Adjust major unit – I used 14 days, you can try something else depending on overall project length.
- Set the axis number formatting to d-mmm or mmm or myy or something else that works for you.
- Add a chart title
That is all. Our Gantt Box Chart is finally ready. Now, go figure why your project is not on track and do something about it.
Displaying Completed Activities:
The easiest way to show completed activities is to change all 3 end dates to the same date: that of the actual end date. This way, you just see a line when an activity is done and a box when there are variations in end dates.
Of course, you can use another helper column to show a vertical line or a symbol of your choice to denote the end point as well. I leave it to you to figure out that portion.

This borders on Excel soft-cell...er, soft-core...porn. My favorite kind.
Wow, that is pimp-TASTIC! I have a question, as a VBA n00b: additional comment boxes stay plain unless I "run" the macro. Is there a way to change all comments, going-forward?
hi Chandoo, well, I like the macro approach. For those who don't like it, there is another way: just add the "draw" toolbar to the shapes toolbar (via Custom etc), click on "edit comment", click on the auto-shape and then choose "draw" drop-down, --> modify auto-shape --> then you even can have a heart or a banner (I like the horizontal banner in in purple :-)) . in excel 2007, you have to add this custom menu that you choose via Excel Options --> Custom --> it is called "change/ modify auto-shape"!!!
best,
@Chandoo. Great Post 🙂
@Tim : the way the macro is coded, it must be run very time.
@Community: If someone has an idea to perform it when opening an existing excel, it should be nice.
@Community: if someone has some code to revamp the commentboxes on all sheets, please share it. 🙂
@Microsoft Excel-progammers: some pimpoptions for the commentboxes should be great.
Cheerio
Tom
For the auto run, please add the codes in workbook:
Private Sub Workbook_SheetActivate(ByVal Sh As Object)
Call Comments_Tom
End Sub
Wow, that was a lot of fun... Thanks Tom!
@Jeff... Now, 5000 people know about your favorite porn... 😛
@Tim ... you can write an event to handle the new comments. I wouldnt recommend it as it is really painful. another option is to use the macro suggested by Yukikomi. It will update comments everytime you activate the sheet.
@laguerriere: very cool 🙂
@Chandoo ... Thanks! This is good stuff. I combined your tip with a tip from Mark O'Brien, then assigned it to a button on Excel 2010's Quick Access Toolbar, to format comments AS I add them. I also like how Mark's code saves me the trouble of backspacing my name out of new comments:
Sub AppendToExistingComment()
'Source: Mark O'Brien at http://www.mrexcel.com/forum/showthread.php?t=57296
Dim oRange As Range
Dim oComment As Comment
Dim sText As String
'Use object variable to hold range.
Set oRange = ActiveCell
'Use object variable for comment
Set oComment = oRange.Comment
'text to be added to the comment box
sText = InputBox("Type text to be added:", "APPEND TO COMMENT TEXT")
If Len(sText) = 0 Then End
'If Active Cell has a comment then append new text to the end of the comment text
If Not oComment Is Nothing Then
sText = oComment.Text & vbNewLine & sText
oRange.Comment.Delete
End If
'Add a comment with the contents of sText
oRange.AddComment sText
DoEvents
Comments_Tom
End Sub
Thank you very much for the code, it seems to be working for the most part; I am having a problem however. Once the routine makes the corrections to the comment, the comment becomes invisible. By invisible, I mean that when I highlight my mouse over it, nothing appears. However, when I right click the cell and click 'edit comment' then the comment becomes visible and I enter edit mode. Upon clicking out of the comment, it simply vanishes again. I've tried to fix this problem by adding a .shape.visible = msoTrue but then every comment is always visible. o_O please advise...
Thank you,
Nick
@Nick- That is because the font color of the comment is white and when you select the color of selection is also white hence you can not see anything. Try to change the color code in the routine to something else. would work
Thanks for that! The code works perfectly!

@ Chandoo - code works great and the comments look super cool. But I have ran into a small issue. In the comments, I am inserting pictures. When I run the macro, for all comments which already have pictures; pictures are deleted. Pls help me retain the pics in comments.
[…] posted some code one of his readers submitted, it "pimps" your comment boxes from those boring black-text-on-yellow rectangles to something more professional and eye-pleasing. […]
love in it
Hi Tom,
This looks really excellent. I am however relatively new to macros / VBA codes so having copy pasted your code in the Developer mode of an Excel file, what are the next steps to use them? Can you please help? Just to recap, I opened a blank Excel workbook, clicked on Developer, copy pasted the comments code and saved the file to the desktop.
Now how do I go about using it to add comments to an existing file? My apologies for asking a question which may be basic to you great geniuses, but I am not there yet and aspire to get there.
Many thanks for helping me with next steps that I need to take so that I can now use the code.
Best Wishes

Dear Dave,
The best thing to do is to copy the macro in the personal.xls(x) file. The personal excel file will always be launched when you open excel so you can use it with every excelworkbook.
Read all about it on the page of Microsoft.
https://support.office.com/en-us/article/Copy-your-macros-to-a-Personal-Macro-Workbook-aa439b90-f836-4381-97f0-6e4c3f5ee566
Once you have the macro in the personal, you can 'call' the macro by the keyboardcombination 'alt+f8' and klik on the macroname.
Hope this clarifies the 'how to'. Good luck with your first steps in the wonderfull world of macro's.
Tom
Hi Tom,
Many thanks. I will try that out. Learning is fun and learning this stuff is even more amazing.
Best Wishes

There is a line 'Dim LArea As Long' which does not appear to be used. Have I missed something?
Dear Gary,
Correct the 'Dim LArea As Long' is indeed not relevant and can be deleted.
Tom
Excellent hack!
For some reason when I opened my file after using LibreOffice Calc, all comment boxes had changed to some arrow shape.
So this macro helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
I used it with the following attributes to get back old style comments:
It helped me from manually changing more than 5000 comments in a worksheet, or having to install some Excel extension.
.Shape.AutoShapeType = msoShapeRectangle
.Shape.TextFrame.Characters.Font.Name = "Calibri"
.Shape.TextFrame.Characters.Font.Size = 10
.Shape.TextFrame.AutoMargins = True
.Shape.TextFrame.AutoSize = True
Thanks a lot!
This was helpful, thank you
I think this is among the most significant
information for me. And i am glad reading your article.
But wanna remark on some general things, The site style is great,
the articles is really great : D. Good job, cheers
Is there code to add to this that will format a particular part of the comment (i.e. make the last sentence in the comment bold and in italics)?
This is fantastic!
How would I add auto-sizing to it?
I tried adding this:
.Shape.AutoSize = True but it gives me an error and as a novice at VBA I can't figure it out.
.Shape.TextFrame.AutoSize = True
Hello I am so glad I found your web site, I really found you by accident,
while I was browsing on Bing for something else, Nonetheless I am here now and would
just like to say thanks a lot for a remarkable post and a all round entertaining blog (I also love the theme/design), I don’t have time to
read it all at the moment but I have book-marked
it and also added in your RSS feeds, so when I have time I will be back to read a lot more,
Please do keep up the fantastic work.
This is GREAT!
How should the code be changed in order to tun once for all worksheets in a workbook?
