Game for some charting awesomeness?
Off late, I have been doing a lot of data analysis and visualization on performance ratings, salary hike, gender pay equality etc. Today let me share you an awesome way to visualize massive amounts of data.
Scenario: Your organization of 3,686 people recently went thru annual performance ratings & review process. At the end of it, everyone was offered some salary increase (from $0 to $24,000 per year). You have 7 business groups. How do you tell the story of all these salary hikes in one chart?
How about the one above?

It’s Halloween time. As adults, we can’t go trick or treating. We can of course dress up in costumes and entertain others. But what about the poor spreadsheets. Don’t they deserve some of this fun too?
Hell yeah! So I made a spider web generator in Excel. Just use it to make a spooky cob web pattern and add it to your report / dashboard / time sheet or whatever else. Surprise your colleagues.Continue »
Over the years, we have discussed a whole heap of techniques to visualize budget vs. actual charts. Today let’s take a ride on this slope again and learn another fun, silly & awesome way to depict target vs. actual progress.
Introducing biker on a hill chart
Biker on a hill!?! Don’t worry, I didn’t fall down on a descent and lose my brain. I am talking about an Excel chart to visualize target vs. actual progress on a time line with biker on a hill analogy. See the above chart, you will know.

First a little back story:
Last Friday (on 29th of July), we (Jo, kids & I) went on a day walk to Red Rocks. It is a rugged coastal walk near Owhiro bay in Wellington. It was a windy & cold day. So why did we brave the elements of nature on this 10km walk? To see seals of course. And we did find a few of them. We also caught glimpses of snowy peaks in Southern Island of New Zealand.
3 Seals Excel Puzzle
Now I can’t take you on the same walk thru internet. There is no Excel function that can teleport you from your office (or home) to Owhiro bay. So I made the next best thing.

Recently I saw an interesting Earth Venus cosmic dance video on Facebook. See the original video below or here.
Although this is not entirely accurate from physics & astronomy perspectives, the dance is a stunning example of patterns that are generated by simple things.
I wanted to recreate this cosmic dance in Excel. How else am I to get my spreadsheet fix on a Saturday?
Here is a quick demo of the final outcome. Read on to learn more about the Earth Venus cosmic dance.Continue »
It is Easter time again. This year, we drove to my brother’s house in Hyderabad (700 km away from my home) to spend a weekend doing absolutely nothing (we will eat copious amount of food, share family memories, laugh and laze). It is Chandoo.org tradition to share few puzzles during Easter time, a la an Excel themed virtual Easter egg hunt. This year, I have prepared an amazing challenge for you.Continue »

Yesterday I saw a tweet from @JanWillemTulp with random snow flake generator.
That got me thinking…? Why can’t we make a snow flake pattern in Excel?
This is what I came up with.

Today is Diwali, the festival of lights. I wish you and your family a happy, bright and prosperous festive time. May your house shower with lots of light, laughter and love.
Diwali is one of my favorite festivals. It is a time when all family members get together, eat delicious food, laugh to hearts content and light up diyas (small oil lamps) to celebrate the victory of good over evil. This year, my kids (who are 6 yrs btw) are very excited about the festival. They are looking forward to lighting up diyas and crackers (fire works).
To celebrate the holiday, I made something for you.

Here are three questions you often hear from your boss:
- What changes are happening in our business and how do they look?
- Do you know how to operate this new coffee machine?
- Why does every list has 3 items?
Jokes aside, our urge to find change in environment predates cave drawing, slice bread and Tommy Lee Jones. So, today let’s examine a very effective chart that tells the story of change and re-create it in Excel.Continue »
ABC analysis is a popular technique to understand and categorize inventories. Imagine you are handling inventory at a plant that manufactures high-end super expensive cars. Each car requires several parts (4,693 to be exact) to assemble. Some of these parts are very costly (say few thousand dollars per part), while others are cheap (50 cents per part). So how do you make sure that your inventory tracking efforts are optimized so that you waste less time on 50 cent parts & spend more time on costly ones?
This is where ABC analysis helps.
We group the parts in to 3 classes.
- Class A: High cost items. Very tight control & tracking.
- Class B: Medium cost items. Tight control & moderate tracking.
- Class C: Low cost items. No or little control & tracking.
Given a list of items (part numbers, unit costs & number of units needed for assembly), how do we automatically figure which class each item belongs to?
And how do we generate above ABC analysis chart from it?Continue »

To all our readers & friends from USA,
I wish you a happy, fun & safe 4th of July.
For the last 4th of July (2013), we (Jo, kids & I) were in USA. We went to Washington DC to meet up a few friends for that weekend. And we had one of the most memorable evenings of our lives when we went to national mall area in the evening to watch beautifully choreographed fireworks. Kids really loved the amazing display of fire-crackers and enthusiasm.
While we all are back in India this time, it doesn’t mean we cant celebrate 4th of July. So I made some fireworks. In Excel of course.
Here is a little Excel animation I made for all of us.

Just like millions of viewers around the world, I too have been spending hours watching FIFA world cup football matches on TV. I don’t like spending hours watching TV. But when its FIFA world-cup time (which is once every 4 years), I am glued to the idiot box. Blame it on PaWaRa, my school teacher in 8th grade who instilled this passion.
So while watching the match day before yesterday (it was Holland vs. Chile), the commentator said, “This has been a world-cup of late goals” as both teams maintained 0-0 until 77 minute mark when Leroy Fer scored a goal for Holland.
That got me thinking,
Is this really a world-cup of late goals?
But I quickly brushed away the thought to focus on the match.
Later yesterday, I went looking and downloaded all the goal data for 2006, 2010 & 2014 FIFA world-cup matches (2014 data for first 36 matches).
Lets examine the hypothesis “2014 has been a world-cup of late goals”.Continue »
Hello everyone. Stop reading further and go fetch your helmet. Because what lies ahead is mind-blowingly awesome.
About a month and half ago, we held our annual dashboard contest. This time the theme is to visualize state to state migration in USA. You can find the contest data-set & details here.
We received 49 outstanding entries for this. Most of the entries are truly inspiring. They are loaded with powerful analysis, stunning visualizations, amazing display of Excel skill and design finesse. It took me almost 2 weeks to process the results and present them here.
