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.

An excellent solution, especially for large data sets.
Another solution without using solver would be to assign the player with the highest score to Team 1, the 2nd to team 2, 3rd to team 3, 4th to team 3, 5th to team 2, 6th to team 1, 7th to team 1 and it continues. This method would end up with a Std Dev of 0.001247219. This works best with a distribution with lower Std Dev for the dataset.
Full Disclosure: this is not my idea, remember reading something a few years ago. Think it may have been Ozgrid
thinking back I now remember why I read about it. About 10 years back I had to distribute around 300 team members into 25-30 odd teams. Used this method based on their performance scores. I used the method I described to do this and the distribution was pretty fair.
Solver would have saved me a ton of time though 🙂
I think the issue with you first Solver approach was that you took the absolute value of the sum of team deviations (which should always be zero except for rounding) instead of the sum of the absolute values (which is a reasonable measure of how unbalanced the teams are).
Here's another simple algorithm you could use: you start from the top (with players sorted from high to low), and at each step allocate the next player to whichever team has the smallest total so far. You can implement it dynamically with some formulas so it will update automatically when the data changes.
If the scores were more widely distributed (so that this might end up with not all teams the same size), you could add a constraint to only pick among the teams which currently have fewest players at each step, or just stop adding to any team when it hits its quota.
When I tried it on the sample, I got the three teams below, with a STDEV of 0.000942809 (i.e. about half of what Solver got to).
Team 1: John, Hugo, Tom, Josh, Eric, Zane, Charles, Andrew
Team 2: Barry, Michael, Kenny, Joe, Xavier, Patrick, Oliver, William
Team 3: Henry, Steven, Ben, Frank, Kyle, Edward, Cameron, Lachlan

Hi,
I was looking at all the solutions and this is closest to what I intended to do. I am dividing a bunch of players into 3 soccer teams. Players availability is also a factor while deciding the teams.
So the steps the excel needs to do is as follows:
1) In availability column if "yes" go to next
2) Equally divide 'Goalkeepers', 'Strikers', 'Defenders' basis their quality
So the end result gives each 3 teams a balance of players playing at different positions.
Can this be done on Google spreadsheet with only availability as an input from the user and rest calculates by itself.
Sorry for asking such a pointed question, but I have been struggling to find a solution for it for sometime now!
Hi Ishaan,
I am working on a similar problem at the moment, so I am wondering if you ever found a solution and if you are willing to share what you did.
Hi everyone, this is a variation of the famous Knapsack Problem https://en.wikipedia.org/wiki/Knapsack_problem.
I had to use a VBA implementation recently as part of a problem, where we ar trying to allocate teams of an organization into different locations (we are a large company with many different team). The goal was to optimally allocate teams to individual buildings without putting too many teams into one building and not splitting teams apart.
As we had around 400 teams of different sizes, solver couldn't handle it anymore. Luckily there is a Knapsack algorithm implementation in VBA readily available on the internet :).
I also went with a heuristic approach first!
An interesting mathematical solution but what if Eric and Xavier can't stand each other or Patrick is best friends with Steven - the real life problems that effect "even" teams.
@Joe
You can add more criteria like
If Eric and Xavier can't stand each other
=OR(AND(E15=1,E16=1),AND(F15=1,F16=1),AND(G15=1,G16=1))
It must be False
If Patrick is best friends with Steven
=OR(AND(E5=1,E17=1),AND(F5=1,F17=1),AND(G5=1,G17=1))
It must be True
Note that the 2 formulas above are exactly the same
except for the ranges
One must be True = Friends
One must be False = Not Friends
Nice Post!
Just one question What if number of players are not even or equally divisible.
Nice post Hui!
I download your workbook and just try to change in options the Precision Restriction from 10E-6 to 10-8 and the Convergence from 10E-4 to 10E-10. The process take almost the same time, but the results was great.
The standard deviation I got was 0,000471.
Team 1: John, Tom, Kenny, Frank, Eric, Xavier, Edward, Zane
Team 2: Steven, Hugo, Ben, Joe, Josh, Oliver, Cameron, William
Team 3: Barry, Henry, Michael, Kyle, Patrick, Charles, Andrew, Lachlan
Great application of Solver! Thanks for the link!
Great explanation. Well done... However, I tried with 6 teams of 4 players and solver never did finish.
How about vba code for the same data set.
I have 3 column A B C wherein A has text and B has number Wherein C is blank. And in C1 been the header C2 where I want the name to come evenly distributed the number which is in Column B.
My Lastcolumn is 1000.
Sorry if I'm being slow here, but how is 'Team Score' calculated? I've gone through the explanation several times but it seems to just appear.
@Hrmft
This process uses the Solver Excel addin
Solver is effectively taking the model and trying different solutions until it gets a solution that meets all the criteria
Then solver puts the solution into the cell and moves to the next cell
So yes it appears to "just appear"
Hi ! Thank you so much ! Works great 🙂
I cannot get the fourth Equation to work in my excel spreadsheet
You have =($E$2:$G$25=0)+($E$2:$G$25=1)=1 as a SUMIF solution, I have, =($F$2:$H$13=0)+($F$2:$H$13=1)=1 as my solution but it does not work. The only thing I changed is the ranges. Any suggestions?
Thank you.
Jim
