We all know that bar charts can be used to display values spread across various categories or times. We also know that pie charts / donut charts can be used to display percentage breakup of various quantities in a sum total. How about mashing up both to create a Donut Bar chart?
“oh, donut what?!? It sounds like a brand new junk food from dunkin’ donuts”
Well, not really. It is a mash-up or combo chart using which you can display, for eg. sales over last few years along with percentage break-up of individual products. See below to understand.
In the above chart we have mixed a bar chart with a donut chart and sprinkled it generously with a scroll bar form control.
In this charting tutorial, we will learn how to cook a donut bar chart using Microsoft Excel. Scroll down the page to get the downloadable workbook to see this in action.
Recipe for making a donut bar chart
A good donut bar can be healthy while adding variety to your regular menu of charts. To make a neat looking donut bar chart, just follow the recipe.
Ingredients:
Sales data (finely chopped – year vs product level), one donut chart, one bar chart, one scroll bar form control and 5 minutes of spare time.
Step 1: Get your dough, err, data ready
As with any chart, we need the right data in right format to make a perfect donut bar chart.
I have arranged the data for our chart in the below format.
The last column shows the values as per scroll bar position. (more on this in the next steps)
Step 2: Insert a scroll bar control and link it to a cell
Go to developer ribbon tab and insert a scroll bar form control. (learn more about turning on developer toolbar in excel 2007)
Once you have the scroll bar, link it to a cell, say B18.
Also, set the scroll-bar minimum value as 1, maximum value as the number of years you have (in our case it is 14) and incremental change to 1.
Step 3: Determine product-wise breakups and totals based on scroll bar selection
We can use INDEX() excel formula to do this.
What is INDEX excel formula?
INDEX formula (examples) returns a specific value from a range of cells by taking the row and column of that range as input. For eg. =INDEX(A1:C10,2,1) will return the value in 2nd row, 1st column, ie, the value in cell A2.
So, how to write the INDEX formula in our case?
That is your home work. Just use the kitchen sink to experiment.
Once you are done, the product-wise breakups should be listed in a tabular format like this.
Step 4: Put everything together and boil for a minute
We have done all the ground work required to make the donut bar chart. Now, We just need to put everything together and make some charts. Here we have 4 small steps.
- Insert a donut chart using the product-wise breakup data
- Insert a bar chart with the yearly totals
- Insert another series in the bar chart to show the selected year total. Completely overlap this series with the totals series.
- Position everything together.
Finally adjust formatting and colors as per your taste.
That is all, the donut bar is ready for consumption. Serve hot or chilled. The donut bar tastes great with a cup of coffee.

Also try a Bar Pie chart, just follow the same recipe, but replace donut with pie.
Please tell me how your donut bar tasted using comments. 🙂

I would like to see actual hash-tagged DM tweets go out to the specific information consumers. That would be an interesting way to communicate the key daily data to interested parties.
A Twitter-like secure application like Yammer might be a good fit with this.
For example, how about daily tweets to selected user groups (secure) that would display sales, bookings, cash receipts, cash disbursed and a second version that would show the same info for MTD, QTD or YTD figures.
@Dan, it would be great. I did not taught about implementing it on this dashboard because twitter is blocked to the whole intranet here. However, there's a discussion here about how can we send these tweets to blackberries (probably through e-mail) automatically. (I'd like to see this implemented on a jabber restricted network as well, but here it'll probably not happen)
The wrap-up versions you mentioned doesn't apply to my particular scenario, but on a sales tweetboard it would be a great tool indeed - choosing who will receive which message according to hashtags. I'll think on something, thanks for the advice. 🙂
(Ah, btw, I'm Fernando... 🙂 )
@Dan: That is a fun idea. Instead of tightly integrating twitter functionality with a dashboard, i think it would be cool if we have a "tweet this" button that users can click after selecting a range of cells. We can easily show a dialog with the concatenated output of the selected cells and ask user to edit the text and eventually "send to twitter".
For eg. you can select the annual sales figure cell and click on "tweet this" button upon which a dialog will show the value. Then you can pre-pend it something like "DM @boss look at our sales this year: "
@Aires.. thanks once again.
Wow it looks really good. Not sure though how much the tweet facility would help in real world project management, but certainly having a dashboard on a project should be a key deliverable when learning how to manage a project
The other use of this is during the software development life cycle especially when you have parallel streams of development and testing going on. Using a dashboard is a quick way for everyone on the team to see where the project is at and how it all fits together.

Hi Chandoo,
I purchased the project management toolkit but the dashboard shown above with the imbedded scroll bars. Is it included in the project pack??
Thanks
Sue
The gantt chart section of this dashboard is similar to one I have recently created: http://xlcalibre.com/hr-dashboard-gantt-chart-traffic-light-reportIt has a similar approach with scroll bars, but has a couple of additional features. I've tried to incorporate a traffic light report element, and also allow the timescale to adjusted so that can view it by days, weeks or months.I really like the other tables that you've incorporated, I may well try to replicate them to improve my version!
I am a monitoring and evaluation consultant in international development, and one of the services I offer is to help non-profits and foundations develop performance dashboards. I often advise them to develop dashboards for ongoing programs, rather than for one-time or pilot projects, because of the time involved. I am trying to find out from a few people how long it takes you to develop a project management dashboard, and to what extent the indicators vary from one project to the next.
