Few days ago, we learned how to create a pie+donut combination chart to visualize polls around the world in 2014. It generated quite a bit of interesting discussion (47 comments so far).

I really liked Roberto’s comments on the original post and a charting solution he presented. So I asked him if he can do a guest post explaining the technique to our audience. He obliged and here we go.

Yesterday was Halloween. To our readers who are not familiar with it, ‘Halloween is a colorful festival with lots of costumes, scary stories, theme parties and trick-or-treating, celebrated on 31st October, every year.” I have never celebrated Halloween as it is an unknown tradition in India where I live. But that is no excuse. Especially when the celebration calls for colorful clothes, scary themed houses and shrieking kids.
Of course, we are not going to have a traditional Halloween. Because,
- At our house, we use pumpkins to make sambar, not lights
- The only ones with costumes in our house are my kids.

It is so important that, whenever I teach (live or online), I usually dedicate 25% of teaching time to INDEX().
Enough build up. Lets get cozy with INDEX.Continue »
