Recently I saw a big screaming ad that said “the chartbuster rules”. Of course, I know that chartbusters rule. Not just because I was one of them
So I got curious and read on. And I realized the ‘chartbuster’ is actually a car, not some cool, spreadsheet waving, goatee sporting dude like Jon Peltier. What a bummer!
And then to my horror of horrors, I saw the exploding 3d pie chart, with reflection effects & glossy colors. And the sole purpose of the chart is to create an impression that Verna sells better than any car in India.
Today, lets talk about this chart and alternatives for it. Read on.Continue »

Do not worry, you are not time traveling or seeing things. Its just that, this year I have decided to publish our Easter Egg a few days early.
And oh, I have 3 reasons for it:
- 2 of my favorite festivals – Easter & Holi (a festival of colors, celebrated in India) are this week. Holi is today (Wednesday) & Easter on Sunday.
- My kids are super excited about Holi as this is the first time they will be playing it. So we have family time from today until Wednesday and I do not feel like writing a blog entry on Friday
- I like to have 3 reasons for everything.
Hence the Easter Egg is advanced a few days. But it is just as fun (or may be better) as previous Easter eggs.Continue »
Lets say you are responsible for sales of 100s of products (which belong to handful of categories). You are looking at sales of each product in last month & this month. And you want to understand whether sales are improving or declining by category. How would you do it?

When comparing 2 sets of data, one question we always ask is,
- How is first set of numbers different from second set?
A classic example of this is, lets say you are comparing productivity figures of your company with industry averages. Merely seeing both your series as lines (or columns etc.) is not going to tell you the full story. But if we can shade our productivity line in red or green when it is under or above industry average… now that would be awesome! Something like above.Continue »

My heartiest Diwali wishes to all our readers.
The spirit of Diwali is to encourage people to spread joy, celebrate good things and throw away darkness (evil). These ideas are universal. So let me wish you a very happy Diwali.
Diwali, festival of lights, is celebrated in the month of October / November. It is one of my favorite festivals since childhood. A time when all family members get together, celebrate all the good in their life, laugh and light a few fire crackers (fire works).
This year, our kids (Nishanth & Nakshatra) too are excited about the festival. They are eager to light diyas (small lamps), watch the fire works and enjoy. Naturally I do not feel like opening Excel.
Sometime during my morning coffee, I thought “hey, why not create a small Diwali greeting using Excel?”
So here we go.Continue »

And that is where we begin.Continue »
Today, lets talk about indexing, a technique used to compare changes in values over time.
What is indexing?
Lets say you want to compare prices of Gold & Coffee over last few years. Gold price in 2011 (oct) is $1,655 per ounce. And now (sept 2012) it is $1,744. Like wise, Silver price in 2011 is $32.06 and in 2012 it is $33.61. How do we compare such diverse numbers?
First we need to calculate price of Gold and Silver in 2012 assuming their starting price is 100. This can be done with simple arithmetic.
Now, we can easily compare the prices. Looking at the indexed prices, we can conclude that both Gold & Silver prices have gone up by similar percentage (~5%).Continue »
