This is a guest post by Chandeep. He won our recent dashboard contest and kindly agreed to share the technique and process for creating such an awesome dashboard with all of us.
Hi to all the awesome people at Chandoo.org
Quick Intro – My name is Chandeep Chhabra and I live in Gurgaon, India. Luckily Chandoo’s 2016 Dashboard contest, my Dashboard entry was picked up as a winning entry. Thank you so much for all your appreciation and likes
A few days later I reached out to Chandoo asking him to let me write everything about this dashboard, right from the thought process I followed to finally making a ticked and tied dashboard.
What I am going to cover in this post ?
Since we are talking about an entire dashboard here, this is going to be a long post (I mean really long). Here is what I plan to cover
- How did I plan this Dashboard ? – All my Dashboard pre-work is included here
- How did I create the Dashboard – This all about number crunching, formula writing, setting up things etc.. I am not going to discuss the formulas in detail but I will give you the overall logic and the formula behind it. To make things structured I have divided this part into 2 main sections
- Screen 1 Calculations – Everything about the 1st screen (company comparison)
- Screen 2 Calculations – All about screen 2 (overall market)
- How did I format the Dashboard – I discuss everything right from colors themes to the overall look and feel. Again the formatting is divided into 2 sections
- Screen 1 Formatting
- Screen 2 Formatting
- How much time did I spend creating it – Specific breakdown into hours for each section
- Mistakes that could have been avoided – A few mistakes that I personally found in my work that could have been avoided
Alongside this post, I have also put together a video to explain this dashboard you can get the video + resources here
Part 1 – How did I plan this Dashboard !
The first glance at the data made me feel comfortable, since I carry a finance background and have mostly played with financial data. So I came with 2 key objectives
- My dashboard has to answer all important questions that were relevant to the audience/management
The look and feel of the dashboard has to be simple and yet stunning - I am going to breakdown the objective into concrete actionable steps that I took to finally complete this dashboard + throw in some general good practices that I personally follow
Quick Tip: I draw from Chandoo’s 10 step Dashboard Process with a few tweaks of my own
Gathering all important and relevant questions
Chandoo did give us a good head-start about objectives of the dashboard

I also reached out to a few friends and asked them, what additional things would they like to know from the data. The list got a bit bigger. This is exactly what I came up with

I then started quickly crunching numbers and doing analysis to find the answers to the above questions. Once I did all the meaningful calculations, I quickly made a rough sketch (mock) of the dashboard. This mock is to understand 2 things
- How am I going to fit all this data and analysis in the sheet?
- How the overall picture will look like?
Below is how the mock up looked!

Part 2 – How did I create this Dashboard ?
Even before I start showing the workings of the dashboard I strongly suggest you to download the Dashboard and then follow the instructions discussed, it will a lot easier that way.
You can also get access to the explainer video + resources
Screen 1 Calculations – Performing a multiple criteria lookup
Take a look at how the Visualisation and its backend is performing a 2 way lookup
- When you select a Company name (using a slicer), the pivot table stores the value of the slicer (company name) in a cell
- When the cost variable is selected (again using a slicer), the chart highlights that variable. But we are not exploring the chart as of now, We’ll keep that aside for a while

Now here is the Lookup formula used to lookup values for cost variables. Total Variable Cost and Operating Leverage were calculated separately. Note that the formula
- Matches the company name (Company1)
- Matches the Variable Name
- And the year using the Columns Function

Once these values were calculated I directly plugged them in the Dashboard

[One of the techniques used] – How to use slicer without a Pivot Table
Screen 1 Calculations – How the Stacked Chart was made
A regular stacked chart looks like this. One big problem – too many colors!\

Stacked Charts can get pretty hard to read because of multiple colors for each part. Highlighting the variables in the chart was the key to make it look simple to read. Here is how it was done!
Take a look at the logic

We needed a dummy calculation to support the highlighted section.
- Dummy = Sum (Values below the selected product)
- The dummy needed to be dynamic which changes as the user selected the product

Using these 2 calculations (Dummy & Highlighted section) a stacked chart was made

I wrote a pretty detailed post about how to highlight parts of a stacked chart. Check it out if you want to get into more details.
Screen 1 Calculations – How did I generate Comments ?

Notice the comments – Most words just stay the same and only a few words change. There were 2 comments with 2 different messages
- Comment #1 : Shows the absolute change since 2011. Depending on the % change a text tag is added (for eg. moderate / considerable / drastic change etc..)
- Comment #2 : Compared to the previous year which year had the largest % change.This was a bit tricky and the reason why I chose to show it because we wanted to bring out interesting insights (drastic or alarming changes) from the 5 year trend. We needed the following ingredients for setting this up
- Which year had the largest change (+/-) over the last year
- How much change has happened (i.e. the exact %)
- Tag (moderate / slight / no change etc..)
The first thing was to set up a Comments Reckoner table

Nothing fancy about this, it is simple 2 columnar data with % change and an appropriate tag along with it. All this data was manually created! We will use this reckoner to lookup an appropriate tag for % change calculations
Working for Comment #1

The calculations are pretty straight forward
- We calculating the absolute % change since 2011
- Using that % change we are looking up for a relevant comment tag in the comment reckoner. Since we are working with a range (between 90% – 50% = drastic change) the lookup method used is approximate match
- After calculating % change and tags for all the variables we needed to narrow it down to only the variable selected

Which was done using a simple Index-Match formula to find the % change and tag for the relevant variable selected
Working for Comment #2

Let’s take a look at each of the 4 parts
- Finds the change over last year for each variable
- Finds the position of the maximum change. This position number will help us find that in which year the change happened
- Calculates the % change that happened
- Adds a tag relevant (from the comment reckoner) to the % change
Using the above calculations, now we lookup for the relevant variable selected

Just like the previous one a simple Index formula for looking up the relevant % change, tag and year
Then I concatenated all these calculations to write comments and used the camera tool to create a linked picture and pasted them in the Dashboard

Phew!! that was some work.
If you have reached till here you might be interested in taking a look at an explainer video + resources that I have put together on this Dashboard
Screen 1 – Overall Layout !

Since I had to show comparison between 2 companies therefore both the frond end and back end calculations were set up in 2 blocks – Left side for 1st Company Selected and Right Side for 2nd Company Selected
This also made it easier for anyone to see my workings and understand how things are formed!
Quick Tip: It is important to layout your calculations clearly! It not only becomes easier for you but also for anyone else to understand your model
Screen 2 – Overall Market

Setting up this screen was not complex apart from conditional formatting. There were 3 major things
- 5 Pivot Tables for each year sorted in descending order (that will enable ranking)
- Slicer for selecting any company and pivot table to store the value
- Slicer for selecting any variable and pivot table to store the value. Note that the variable slicer was connected to all 5 pivot tables
Screen 2 – The tricky part, Conditional formatting
I applied 2 layers conditional formatting
- Layer #1 The selected company should be highlight for all the years
- Layer #2 Icon sets should display the change from last year has been positive, negative or no change
Layer #1 – Conditional formatting for highlighting the Company

- I wrote a simple formula to equate the company selected in the slicer with the companies displayed
- Where ever the result was true the format set was blue color
Layer #2 – Icons that display change from last year
Since icon sets do not accept relative cell referencing so I had to play a trick. I first wrote a formula to find out last year’s value for the selected company and selected variable. This was the formula is copied down in 4 cells and pasted in each column containing values
A key thing to note is that the below formula also accounts for 2 additional factors
- If the user selects Profit – Green icon should be displayed when the profit is up from the last year and a red icon when the profit has dipped from last year
- If the user selects any Cost Variable – Green icons when the cost has gone down from the last year and red icons when the cost has increased from last year

Then I applied conditional formatting (icon sets) for each value separately and referred to each cell containing the above formula

and that completed all the number crunching and setting up of the Dashboard! The next big thing was to format this beast and make it a beauty!
Wow..!! If you are still hanging around I would love to share with you an explainer Video + Resources that I have put together for you. I think you’ll love it
How did I format the Dashboard ?
Screen 1 – Headline Bar
![]()
- I set up the headline bar in dark grey because I din’t want to overwhelm the dashboard with too many colors.
- I used Red for highlighting the chart and Blue for Company slicer
- Also in the past I have read many reports from Bain & Co and they use red with grey/black, so I knew that color combo looks pretty cool !
Screen 1 – Slicers for Companies
![]()
- I spent a lot of time customising the look and feel of the slicers
- Mostly removing the non essential elements and make them look seamless as if they are a part of a web based report
- If you want this same format
- Just copy and paste this slicer in your workbook
- You’ll find a new style created in slicer options
- Now apply the style on your existing slicer and delete this slicer! Done
[Related] – Learn to work with slicers
Screen 1 – Formatting Stacked Chart

- I wanted the charts to look simple and clean
- I included the vertical axis and not the data labels. Instead I highlighted the values (via conditional formatting) below
- The years (horizontal axis) was put on the top so that it becomes common label for the chart and the values below
Screen 1 – Formatting Cost Variable Slicers, Values and Comments

- Note a few things about Slicers
- Just to make sure that slicers look like clickable and yet NOT look like buttons I gave a little stick at left side in red. It was a trial and error exercise but it did the trick
- Just to be more explicit I even wrote it on the top “Pick a Cost”
- Arranged the slicers accurately so that they look seamless and appear as spreadsheet values
- Formatting Values
- I applied 2 layers of conditional formatting
- Color the values in red for the cost variable selected
- If the total variable cost is select then apply bold formatting on Power, Other, Variable Cost and Freight & F
- Other than that there was a slim border between each row
- I applied 2 layers of conditional formatting
- Formatting Comments – There no major formatting done here. These are just linked pictures
Screen 1 – Overall Formatting – I did some overall formatting to tighten & secure the dashboard and make it look compact
- I protected the sheet (with no passwords)
- All objects (lines, charts, boxes / shapes) were locked
- The slicers were left unlocked, else clicking wouldn’t have happened
- The sheet name tab was removed
- The headings (column and row number) were hidden
- The formula bar was removed
- The extra rows and columns were hidden
[Related] Hiding Options in Excel
Screen 2 – Headline Bar
![]()
- The slicers on screen 2 were exactly the same as screen 1.
- The 2 buttons interchanged appearances when clicked, which made it look like dynamic but technically it was just moving from one sheet to another
Screen 2 – Slicers Formatting
![]()
- Formatting of both slicers were consistent
- Red for cost variables
- And Blue for Companies
- A label was put up on the top, just to make things more explicit
Screen 2 – Formatting Years, Data and Legends

- Formatting Years
- They were slightly in a bigger font than the data
- And I placed slim separators in between
- Formatting Data/Values
- Most of this formatting came from Conditional formatting as explained above
- I also left a column with a very narrow width in between each year as a separator
- Formatting Legends
- The legends were pasted as a picture
- The legends also depicted 2 inferences (for cost and profit separately)
Screen 2 – Overall Formatting
- I carried most of the formatting practices from screen 1
- Additionally I also made sure that the total width of Screen 1 is equal to Screen 2
How much time did I spend in creating this Dashboard ?
- Dashboard Pre-Work – Planning, Rough work and Mock Dashboard (1.5 Hour)
- Number Crunching and Analysis – (2 Hours)
- Formatting and Creating the look and feel – (2.5 hours)
I gave 3 sittings over 3 days to finish this task 🙂 . You can also watch a quick video explaining the entire dashboard
Mistakes that could have been avoided
I found 2 mistakes that could have avoided.
- The variables were static (hard coded) and they did not link back to the data. That could have been a problem or could have required additional work when
- The variables change completely
- More variable were added. In those cases the Dashboard was not capable of adapting to the changes automatically
- It could have been solved by a formula (to extract uniques) or by power query. Thanks Abhay for pointing that out 🙂
- The Overall Market Sheet could have had some additional analysis on the overall trend or may be an infographic. The space utilisation was not optimum
With all that work put it, I finally closed the Dashboard and sent it to Chandoo! and it clicked 🙂
I have put together an Explainer Video + Some additional resources on this Dashboard. I sure you’ll love them
Closing ..!

If I could have the same quality of graphics and illustration in Office Apps, I would certainly use it.
If I could have the same quality of graphics in Office Apps (Excel, PPT) I would certainly use it.
Chandoo,
First, let me say I love your blog. I like this post, and I think that technically (in terms of readability of data) your argument is correct. The bar of bars, and the table, are much better for readability and accuracy, and as you say would be much easier to produce.
But these points ignore the context of the chart. If the chart was part of a scientific paper, your solution would be a valid one. The context in this case is an illustrated atlas of wildlife. A companion graphic to go with written text. The importance of aesthetic goes up over readability and accuracy. Much of the data and points (I assume) will be covered in the text.
There's always a pure technical tufte-esque argument. But I sometimes think it ignores the value of aesthetics. (Which I admit are quite subjective)
Great post though. Thanks.
The Treemap makes the scope of the data much clearer! The 3D pie chart depiction is deceptive.
This reminds me of the videos ive seen on the internet where it compares the relative sizes of the earth with the larger planets, then the sun, then other stars in the galaxy. Eventually there is an image showing the largest star in the sky with a little pixel representing the sun.
My point is if you varied the size of the charts it would help convey the message. The first chart (salt vs fresh) would be the biggest and the rest would be arranged in descending order. I feel this would be more accurate.
It may be helpful to consider the advice of Steven Few and Edward Tufte regarding pie charts in general. To summarize, they are seldom the most useful way to present data. Here's Few's thoughtful piece on the subject.
http://www.perceptualedge.com/articles/08-21-07.pdf
Try putting the percentages on the bar charts instead of actual amounts. Lakewater would be .013 % instead of 52.
That is very good pie chart example.
Please send example file if it is possible.
It will work , even though colors may be confusing , it can be labeled well . Also it can be called as the drilled chart , as it drills in information further , like the first chart may show business in a region , second may drill into a particular region , thrid may further drill into wat products are there in that region . It works well for me , i would more vote for the 2 nd option .
Overall all this site is awesome ,
p.s : just like me
The risk with pie of a pie of a pie chart is that Jon may have a seizure by looking at it. Also, it isn't easy to read. 😉
I dunno. The only thing worse than a pie chart is a cascading series of pie charts. I don't even think they really lend themselves to this sort of thing. It just becomes a big hide-the-ball game with your viewer.
Those goofy connectors between the pies are pure chart junk. I can't really tell if the second chart has 2 series or 3 - because the connector is a different color than the 2 labeled slices. Despite that, even whereas the drill down kind of works, still the individual components suffer from the same old weaknesses that 3d pie charts have.
Use a large bar chart as your "cover story", and fill in the sub points with smaller bar charts - or even go grab the Fabrice SFE project for extra butter. Use page orientation, color, and some text styles to guide your audience through the drill downs.
FWIW, if you check out the guy's site, you can find several other truly mortifying charts:
http://www.andrewdavies.com.au/index.html
The methane emissions one is particularly heinous. Although, I'm kind of debating what I think about the 'Glacier Changes" chart. I'd kind of like to see the data on that to see how it would look in a more traditional horizon chart.
Thank you, that was scary. I don't understand the "Glacier changes" Chart at all...
Its a very nice way to represent the data, especially when we have sets and sub-sets within the data.
I like these!
Except for the fact that they aren't dynamic and hence must be setup manually each time
It would also be nice if they could be interrogated as in select a different segment and the new data falls out automagically, but then none of the standard Excel charts do that either.
I'd like it better if the bars were stacked. How about this idea (I hope I can convey it in words):
First bar is vertical and stacked.
Second bar is horizontal, stacked horizontally and the same proportion had it been on the first bar.
Third bar is vertical, stacked vertically and the same proportion had it been on the second bar.
Then it would really look like you are zooming on the chart, like the Powers of Ten video, or maybe like the golden ration spiral.
These looks shunting but setting up for each step makes kicks them out. However if these can be arranged automatically by native excel or by VBA, these will be the part of my "Archery"
I agree with Chandoo's Suggestion about the Bar Graph which represents data in a very appropriate manner. Even I prefer doing the same. I seldom use Pie Chart unless required.
That's a real nice example of a missleading infographic. But to be honest, I think chandoos suggestion is not much better!
Why are pie charts bad? I think because they don't show the real size-relations. The biggest pie in that example ist 300k big. The 2nd one has only the size of 10k, about 3% of the first one. Niether the pies nor the bars show the real sizes. I jnow, it's hard to show the sizes because the values of the second and the third pie are so small. But that's what visualization are about - showing relations to allow the reader to see the real sizes!
So how to show the real figures?
First possibility is o use a 1:1 scaling. Well then, you need a very big screen to show also after a 90° rotation, wihich I would prefer because it's a structural comparison and not a timeline. Maybe that solution is not the perfect way.
The other chance you have is to zoom in but to really show that you zoom in! http://www.pro-chart.de/images/Water_Fall.png maybe gives you a first impression what i mean. (i was a quick try, done in 10 minutes)
The next way is, maybe to fold the bars like in the financial report 2011 of the Post of Switzerland page 22. That chart is based on an excel chart. Maybe can explain you how to do it 😉
Financial Statement: http://www.post.ch/en/post-startseite/post-berichterstattung/post-berichterstattung-service/post-berichterstattung-downloads/post-gb-2011-finanzbericht.pdf
page 22: http://www.pro-chart.de/images/FS_Schweizer_Post.png
A way that is not so very common is to divide the bars in a lot of single datapoints. So maybe the 390k bar then consists of about 5,000 single datapoint. That's not possible - it is! Have a look:
http://www.pro-chart.de/images/Dotted_WF.png
It's pure excel!
Now one single point ist 0,2% of the whole (in the example above). Add more datapoints and you can visulize the very big and the very small numbers!
Wish you a lot of fun - visualizing with excel can be very powerful!

Hey Joerg,
I don't dig so much the dotted waterfall thing. But this is kind of awesome:
http://www.pro-chart.de/images/FS_Schweizer_Post.png
Can you help me on the bar of bar graph? Would it be possible to create that from pivot table? Can you show me how to create the bar of bar graph?
do nothing but say "Awesome!"
You are a Rock star.....This seemed an answer as if someone was reading my mind and just had the solution to my questions on what I exactly was looking for .....What a Fab !!
can u explian me step by step
Can anyone please explain how to make this chart please.
Do you mean the pie of a pie chart or the folded bar chart?
Joery PIE OF PIE Chart please
Can someone please explain how to make PIE OF PIE Chart.

Normally I don't learn post on blogs, however I would like to
say that this write-up very compelled me to try and do so!
Your writing style has been amazed me. Thank you,
quite great article.
This is very impressive, I would like to learn how to build this for myself. I have tried for some time now, is there a step by step process on how to create these waterfall pie of pie charts?
I am novice to excel and use it very seldom. But your blog contains to the point information one needs to get going.
I was searching for a trick to do a Pie chart drill down - for example the first pie chart shows how the prices are distributed between perishable and non-perishable items.
Now if we want to know how the perishable items are distributed - one can click the segment and it will draw another pie chart with distribution of all different perishable items (milk,meat,fruit,veg etc)
So do you have any such trick?

electrojit
I like the look of your pie of pie of pie chart, although I understand that the relative size of each pie does not represent the actual percentages.
