Recently, I saw this chart on Economist website.
It is trying to depict how various cities rank on livability index and how they compare to previous ranking (2014 vs 2009).
As you can see, this chart is not the best way to visualize “Best places to live”.
Few reasons why,
- The segregated views (blue, gray & red) make it hard to look for a specific city or region
- The zig-zag lines look good, but they are incredibly hard to understand
- Labels are all over the place, thus making data interpretation hard.
- Some points have no labels (or ambiguous labels) leading to further confusion.
After examining the chart long & hard, I got thinking.
Its no fun criticizing someones work. Creating a better chart from this data, now thats awesome.
So I went looking for the raw data behind this graphical mess. Turns out, Economist sells this data for a meager price of US $5,625.
Alas, I was saving my left kidney for something more prominent than a bunch of raw data in a workbook. May be if they had sparklines in the file…
So armed with the certainty that my kidney will stay with me, I now turned my attention to a similar data set.
I downloaded my website visitor city data for top 100 cities in September 2014 & September 2013 from Google Analytics.
And I could get it for exactly $0.00. Much better.
This data is similar to Economist data.
Chart visualizing top 100 cities
Here is a chart I prepared from this data.
This chart (well, a glorified table) not only allows for understanding all the data, but also lets you focus specific groups of cities (top % changes, new cities in the top 100, cities that dropped out etc.) with ease.

Click here to download this workbook. Examine the formulas & formatting settings to understand how this is made.
How is this visualization made?
Here is a video explaining how the workbook is constructed. [see it on our YouTube channel]
The key techniques used in this workbook are,
- SUMIFS, INDEX + MATCH formulas for figuring out data
- Sorting data by a particular column
- Conditional formatting to show % change arrows
- Form controls for user interactivity
Since the process of creating this visualization is similar to some of the earlier discussed examples, I recommend you go thru below if you have difficulty understanding this workbook:
- Suicides vs. Murders – interactive Excel chart
- Gender Gap chart in Excel
- Visualizing world education rankings
- Analyzing survey results with panel charts
How would you visualize similar data?
Here is a fun thought experiment. How would you visualize such data? Please share your thoughts (or example workbooks) in the comments. I & rest of our readers are eager to learn from you.

Hi Purna..
Again a great tip.. Its a great way to convert Fractional Time..
By the way.. Excel has two great and rarely used formula..
=DOLLARFR(7.8,60) and =DOLLARDE(7.48,60)
basically US Account person uses those to convert some currency denomination.. and we can use it to convert Year(i.e 3.11 Year = 3 year 11 month) and Week(6.5 week = 6 week 5 days), in the same manner...
This doesn't work for me. When applying the custom format of [h]:mm to 7.8 I get 187:12
Any ideas why?
@Jason
7.8 in Excel talk means 7.8 days
=7.8*24
=187.2 Hrs
=187 Hrs 12 Mins
If you follow Chandoo's instructions you will see that he divides the 7.8 by 24 to get it to a fraction of a day
Simple, assuming the fractional time is in cell A1,
Use below steps to convert it to hours & minutes:
1. In the target cell, write =A1/24
2. Select the target cell and press CTRL+1 to format it (you can also right click and select format cells)
3. Select Custom from “Number” tab and enter the code [h]:mm
4. Done!
Hi, sorry to point this out but Column C Header is misspelt 'Hours Palyed'
good one
So how do I go the other way and get hours and minutes to fractional time?
If you have 7.5 in cell A1,
- Use int(A1) to get the hours.
- Use mod(A1,1)*60 to get minutes.
If you have 7:30 (formatted as time) in A1
- Use hours(a1) to get hours
- Use minutes(a1) to get minutes.
I had the same issue. You can solve it by changing the format as described above:
Right click cell > Format Cells > (In Number tab) > Custom > Then enter the code [h]:mm
([hh]:mm and [hhh]:mm are nice too if you want to show leading zeros)
Thanks guys, these are the tips I'm looking for.
...dividing the number of minutes elapsed by the percent change is my task - "int" is the key this time
It doesnt work for greater than 24 hours
It returns 1:30 for 25.5 hours. It should have returned 25:30
Ideally I would right function as
=QUOTIENT(A1,1)&":"&MOD(A1,1)*60
Sorry, replied to wrong comment....

Clever use of MOD here to extract the decimal part of a number. Divide a number containing a decimal by 1 and return the remainder. Humm. Very clever.
Thanks very much, extremely useful !
