When I saw the Olympic medals won by each country by year infographic on nytimes my jaw almost dropped, go ahead see it and come back, I am sure you will love it too.
It is one of the coolest visualizations I have seen in the recent past and I see infographics all the time, its my passion.
So, I wanted to see if this infographic can be done in Excel, not pixel to pixel, but something close enough to pamper my ego. I was able to create something that looked like this:
Download the Total Olympic medals won by each country since 1896 excel sheet and play with it.
If you want to know how this is done, read on 🙂
1. My first challenge is to get the Olympic medal data per country
Thankfully, Olympics site has the medal counts by country data for each of the 25 editions of the summer games, [click here for 1896] I have copy-pasted the data to my sheet.
2. Next challenge is to find average latitude, longitude for all countries in the world
Thankfully CIA World fact book has the exact data for each country in a table, another ctrl+c, ctrl+v and I have the data in my sheet. [slightly refined data can be found on maxmind as well]
3. Now, the data is not clean
Unfortunately the data copied from Olympics site and CIA fact book doesn’t match as country names were different (USA, United States, United States of America for eg.), country names kept changing (do you know that Australia was called as Australasia sometime back.. :D). So I had to do quite some clean up (mainly using vlookup, filtering unique items etc.)
Finally, I had the data in a tabular format, country names, latitude, longitude, total medals won in rows, Olympic years in columns (1896 to 2004, except 1916, 1940 and 1944 when the games were canceled)
I had to convert latitude and longitude to y and x co-ordinates respectively so that I can plot them on 2 dimensions. I used this logic to do it:
x=(180+longitude)*(map-width/360)
y=(90-latitude)*(map-height/180)
4. Add a scroll bar form control and use it to select the year from 25 Olympic years
This was the easy step. I selected Menu > View > Toolbars > Forms to show the forms toolbar and then inserted a scroll bar control to my sheet. Then I associated it with a cell my sheet and limited the values to change between 1 and 25 (each increment for one of the 25 Olympic years)
Now, I have associated this scroll bar cell to fetch one Olympic years worth of data.
5. Create a bubble chart with the medal data
Now that I have the data in the format of x, y co-ordinates, medal count for each country for the selected year, I have created a bubble chart with this information, showing bubbles at each pair of (x,y) in the list.
6. Finally, show an outline map of the world in the background
The last step was easy, I searched for an outline map of the world and used it as my chart background, even though this is not part of the original NY Times infographic, it helps me in ensuring that the bubbles are indeed shown in the right places.
Of course there are some differences between my infographic of Olympic medal count and that of NY Times’, mainly,
- The bubbles overlap, but there is nothing I can do about it without writing additional logic. But as Nathan points out, non-overlapping bubbles may be slightly inaccurate.
- The other is, color of bubbles doesn’t change based on the continent it belongs to. Well, this can be done by editing the bubble colors manually, so I gave up.
- Finally, very few countries are omitted in this, mainly due to geopolitical changes, like Germanies getting united, Koreas getting separated, more countries becoming China :D, I did clean up 99% of the data, but there is always a troublesome country you never heard of.
Make sure you download and play with total Olympic medals won by each country since 1896 excel sheet

I prefer the red,grey,light grey,black icon set. I've also used in-cell pie charts from Fabrice's Sparklines for Excel as an alert which could also provide another piece of information.

For Excel 2007, your formula should do the same as the Excel 2003 version, so that non-alert rows are blank - if they are 0, the unnecessary green icon will show
Hi Chandoo,
Nice Post !! just to add something for EXL 2003, we can also 4 Ifs and link to the alert data
For Ex: If we have alert data in Cell A2 and want to split in 4 orders namely <25%, 25-50%, 50-75% and 75%< then we can following formula and put fonts as you have suggested :
=IF(A2<0.25,CHAR(153),IF(A2<=0.5,CHAR(155),IF(A2=0.76,CHAR(152)))))
And then using Conditional Formating we can dashboard reflected on different COLOURS as per their respective alert.

The Complete formula [Don't Know how it got cut ]
=IF(A2<0.25,CHAR(153),IF(A2<=0.5,CHAR(155),IF(A2=0.76,CHAR(152)))))
PS : Use in single line [I have split it to avoid cuts 😉 ]
Hi Chandoo..
why it is not displaying the complete formula..
anyways here is the balance
"=IF(A2<0.25,CHAR(153), IF(A2<=0.5,CHAR(155), IF(A2=0.76,CHAR(152)))))"
@Rohit... your formulas are fine. Just that the width of comment area is fixed and hence my website is cropping it at 640pixels. I just edited your formula and added few white spaces so that it wraps nicely.
Very good idea btw.. kudos!
Hi,
Maybe just go for 'bold' ; 'underline' or 'italic' to draw the users attention? Those methods (if those can be called methods) are used cross media type (books, journals, blogs, billboards, ...) to guide the readers eye to valuable information.
Just a basic thought
@Tom.. good idea..

Hi Chandoo,
You certainly grabbed my attention! although I wasn't sure what my brother (Suresh) and cousin (Shyam) were doing right, and I was doing wrong? 😉
I love your blog btw - Many thanks for all your hard work in unravelling the secrets and mysteries of Excel!
Best regards

I thought I saw an advertisment for a book about learning excel called excel himalaya or something. It cost about 35.00 us money but seemed to have the things I need to have my admin assistant to start to use. I was hoping to start with this book and then send her to school if she shows some interest and aptitude. Any help on this would be appreciated. Thanks
Great web site and information!!!!

Hi Chandoo
Firstly thanks for all the cool tips on how to use Excel better.
I am new to the site and have a question which you may be able to assist with but dont know if these comment boxes are the best way of asking ?
I am looking at assets and trying to calculate the depreciation total by taking a year (say 2010) adding the expected life of the asset (say 10 years) then comparing that to a future date (say 2015) using an IF statement. The calculation in normal is - IF((year in col B (2010) plus 10years)>year 2015, add a years depreciation, otherwise leave blank). The converted date value does not appear able to add 10 years in order to compare it to 2015. Am I missing something ?
I use the “IF” Statement in conjunction with Conditional Formatting in MS Excel to give verbiage to alert one of a required action, dependant on a review date. This makes a visual stimulus, plus it clues one as to what the conditional format is trying to warn you about and what follow-up actions are required.
Wow, I'm really impressed with dashboards. I had no idea this stuff was even possible with excel. I'd like to offer an interactive dashboard to my customers, showing analytics of their data. I have a .pdf file with the datapoints. I'd like them to enter the data on my website, and be able to see their data. Is something like that possible.
Hi Chandoo,
I've recently purchased the package for both templates.
In the portfolio dashboard,under the calculations worksheet, I'm attempting to change the date range in the gantt chart to show only the range of the project that starts in late 2013. How do I do this?
Thanks

Hi Chandoo,
I'm new at Excel Dashboard and found your blog really useful and helpful! It's very nice of you that you dedicate your time to do this.
Could you please explain how can I use Alerts based on dates on a Dashboar?
For example, if a target date is coming closer to the actual date, the alert is yellow or red.
I'd really appreciate some help!
Thank you
Where can I download the file Excel of Averall Statistics ???
Thanks a lot.
