Livio, one of our readers from Italy sent me this interesting problem in email.
I would like to prepare an xy linear graphic as representation of the variation of temperature trough a wall between two different bulk temperature i.e. outside and inside a house. This graphic should show the temperature gradient trough the wall thickness. The wall is normally made by different construction materials (different layers, as bricks, insulation, …..) and so the temperature change but not as a straight line with only one slope, instead as few lines with different slopes (see below figure) Calculations are not difficult, and also prepare the graphic also not difficult.
But, I am looking a beautiful solution for x-axis. X-axis should be divided not with constant interval, instead with different length between each sub-division exactly as the different thickness of the wall. This is a correct graphic, because you can show the correct slope of each straight line though each layer of the wall.

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 »

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 »
