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.

Hi Chandoo,
your recent postings include only Excel 2007 templates. Unfortunately the company I work at still runs Excel 2003. Is it possible to get your awesome files in other excel version as well?
Thanks so much for your great excel stuff!
Is it possible to do this for shifts with hours instead of days? To organise a three shift day?
Thanks in advance,
Stelios
In my organization there are 45 employees i need split then into three shifts ex:A shift:14,B shift:14,C shift:14 and week off:3 kindly help me on this.
@Masthan
You need to understand what rules your company has for the various shifts / roster combinations
Chandoo, I once did a shift control spreadsheet for my team. I put one person in each line, the columns were the days. I put a shift code in each cell indicating in which shift that person should work, or if the person were out that day. I have two codes for being out. One is for vacations and one is to compensate days worked in weekends. This way I was able to count how many persons I have in each shift, how many were on vacations and how many were out compensating (that's the term we use here) weekend worked hours.
Later I included the possibility of a person be in two lines one for normal hours other for overtime. This is mainly used for planning purposes. If you would like I can send you an example. The only problem of this spreadsheet is that we don't have a person view, only this consolidated view.
Hi George, I would like to have a copy of your spreadsheet if you can share it.
Thanks in advance, Chuck
Hi Chandoo,
Where is the code located ? is it VBA ? If so , how do you hide it ? Or it is .NET ?
Thx
@Idan
.
No VBA or code, it is all done with Mirrors.
Only Joking,
.
But there is no VBA or code,
It is all done with Named Formulas and Lookups.
Have alook at the cells in the calander area and Named Formulas in the Formulas, Name Manager Tab.
How can i calculate between two or more different workbooks? Please, reply me as early as possible.
@Anand
Open the workbooks you want to link to
Start a formula = and click and change between workbooks as required.
You can use the View, Switch window menu to change workbooks mid formula
The format for using workbooks is
=[Workbook.xlsm]Sheet1!$A$1
or
=SUM('[Book2.xls]Sheet1'!$A$1:$D$10)
etc

What's FortyTwoDays and Calendar in Name manager?
Both are unused and FortyTwoDays doesn't make any sense.
I have a SQL db that contains records of events scheduled/completed on a particular date. Can this method ous building a calendar be used to display those events on the respective day?
Positively awesome!

Dear chandoo,
Try many way to download still can't access. Any way we want to try out 3 shifts with 3 guys in a group .eg Group A Morn, Group B Night and Group C Rest. And every each group must work on sunday to take turns. In fact we are security teams so that's why sunday is required to work. Pls guide and show how to put in the working calendar. Thank you in advance.
I've been trying to copy and/or recreate this to use in a workbook I'm doing for the transportation department I'm working for. I need to have the calendar on the first sheet in my document (it has graph's from data on another sheet). I'm trying to use it to track (with the conditional formatting) accidents and injuries. I've redone the conditional formatting to do 4 different accident types (no injury, near miss, OSHA recordable injury and work loss injury), but when I enter the formula's you have in the calendar portion where it says "DateOfFirst-FirstWeekDay" I can't figure out how you did that. Are you able to help?
I would like to use Excel to solve the following problem for a community work. I want to create a Driver schedule for a given month from a pool of volunteers for a community service. Each of these volunteers can drive only on specific days in a week. I would like to populate the driving schedule for each weekday with primary, secondary and tertiary drivers in a random fashion so that I do not overburden one person. I would greatly any help you can provide.
Hi chandoo,
Thanks for your valuable effort for create this template and let me know how to add multiple employees in the the Roaster.
