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.

Looks good, Mara. Keep up the good work!
Thx Mara, your work is great, congratulations...
wow ! Great stuff Mara !!
I am amazed on the work you did !
What I like about your dashboard
1. The first impression is the colors used. Very smart use of colors that matches each other, easy on the eye - make people wants to find out more !
2. Clear message shown for the tweetboard for Quick overview on the state of situation.
3. Use of creative titles for your charts "Information Desk".
4. Clear and uncluttered charts. Gives reader a clear perspective with good use of charts colors too.
5. Good use of Legend to describe what color meant "Highest Sales out of the three months"
6. Of course, good use of Check boxes and Slider bar to offer interactiveness on your charts.
Suggestions
1. You may want to consider formatting your Y and X axis labels to show thousands, in $500K format instead of $500,000, so you can even made your chart look much neater.
2. Budget Variant Chart - This one is special...I took a second look and try to understand it. I am not sure if this is the best chart to visualize Sales VS Budget and Variances. And the Variance of 16.19% is positive, so u may want to use conditional formatting to make it green color, red if negative.
Overall is Great Work and Great Effort !!! Keep it up and I am so proud of you !

Great Work Maya, just wondering if "5" Scrollable list of various gift shop items, can compare the previous 2 and current month selected in the above picklist, just one more suggestion if we can use top 5 gift category by using donut and bar mix chart to show sales mix for different months
Chandoo I would like to thank you for posting such helpful tricks for creating dashboards, I have learned a lot from your KPI Dashboard demo, I have created one dashboard to compare performce of Sales Associates, thaks a lot again
Thanks for the idea! Great job! You are giving me a lot of inspiratons!
Thanks everyone for the nice comments. I'm such a novice at this so I was so grateful for Chandoo's class and for everyone who submits ideas on his blog.
Francis: Thanks so much for your comments. You're an inspiration. For the budget variance chart, I actually got that idea from one of Chandoo's post on budget vs actual. There was one that was simple and easy to read so I learned how to do that and made it dynamic. I'm open to any other ideas you have for budget vs actual. I'm always looking for ways to improve.
Sabrina: Thank you for you for your suggestion on the top 5.

Excellent dashboard Mara.
The best I like about the dashboard is the choice of colors. They are cool and not distracting. Thanks for sharing the file.
@Chandoo

Great work Mara ! Thanks for sharing .
Mara, I liked the line, "Need to be more helpful." Our government needs to print this line, laminate it and post it in all government offices for the staff to see.
Hi there, i have been recently visiting this blog it is really great, the best one for Excel, wish Chandoo great success ahead.
I have one query, if you protect the data sheet the chart with the checkbox gives and error saying the data is protected and cannot be modified, is there a way around. This is cause if we want to publish this to someone who should only see it and do no changes to the data, is it possible please guide.
This could be a silly but bear me i am novice to excel 🙂
Thanks.
nice work.
inspired me a lot, working on few dashboard projects...
[...] Customer Service Dashboard in Excel 14,326 [...]

dear mara

Dear Chandoo,
The word Dashboard in the heading is misspelt.
Wow. Very Nice work Mara. Next week I am going to take the Course, I will try to post my work here.
Thank you so much for your helpful blog. Always appreciated your tips and tricks.
I am proud that you belongs to our Vizag City.
The above comment, I forgot mentioned about Chandoo, those two paras is about Chandoo. 😀
Thank you Mara!
Thx Mara, your work is great, congratulations…
Great Work Mara!!!!!!!!!!!!!!!!!!!!!!!!!!
Hi Chandoo,
I had been following your blogs for tips and tricks on excel. I am working with Media agency and we collect the data. Now this data has several parameters based on several legends. For eg Class A - legend color red, classB - legend color green and so on. Class A has several characteristics and parameters and heading etc. Now everytime we gather data and make pivot then based on the data in the pilot tables - top 10 we need to insert those in charts manually and also need to change the colors of legends and also. We create nearly 300 slides every month sector wise and it takes nearly our 4-5 days in doing that. Do you have any sample dashboard which will be helpfull to us and we can create it in a day.
Thanks really amazing one,
it helped me in desgining OTACE report
