Today lets take a stroll outside what Excel can do and make something fancy, fun and may be useful.

Nowadays, many newspapers, websites and magazines are featuring info-graphics. An info-graphic is a collection of shiny, colorful & data-full charts (or often pieces of text.) In many of these info-graphics, you can see threaded-donut charts. Not sure what that is..? It is not same as the blasphemy of spoiling a soft, sweet, supple donut with a piece of string. No one should be excused for an offense like that.

What I am talking about is shown above

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). One of the comments was from Roberto, who along with Kris & Gábor runs The FrankensTeam an online library of advanced Excel tricks, charts and other mind-boggling spreadsheet wizardry.

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.

Over to FrankensTeam.

Today lets have a poll. Lets debate if this pie chart about world elections in 2014 is good or bad.

First lets take a look at the chart

This chart, published by The Economist talks about how 42% of the world population is going to vote this year. Take a look and read on to learn how you can re-create this in Excel.

Bar & Column charts are very useful for comparison. Here is a little trick that can enhance them even more.

Lets say you are looking at sales of various products in a column chart. And you want to know how sales of a given product compare with a lower bound (last year sales) and an upper bound (competition benchmark). By adding these boundary markers, your chart instantly becomes even more meaningful.

Lets learn how to create a column chart with lower & upper bounds in this tutorial.

You have been there before.

Trying to compare last year numbers with this year, or last quarter with this quarter.

Today, let us learn how to create an interactive to chart to understand then vs. now.

Demo of Then vs. Now interactive chart

First, take a look the completed chart below. This is what you will be creating.

Finally my Excel classes in USA are over. It was a lot of fun traveling to new cities, teaching Excel & dashboards to enthusiastic crowds and making new friends. As if that is not fun enough, we (Jo, kids & I) are going on a 2,000 mile, 2 week road trip starting today.

Although I am enjoying all this, I also feel bad for not taking enough time to share new tricks, ideas & techniques with you here. So, I have a wacky, wild & awesome plan for you. Join us on our road trip.

That is right. You can join me on our road trip and see what I see, learn some pretty cool Excel tricks, all while sipping coffee and stretching legs in the comfort of your office cubicle.

Tony sends this chart and asks if it can be done in Excel.

It sounded like a good challenge for a lazy Sunday morning. So here we go. (Posting it on Monday).

Now I could not get an oil rig photo or that data. So I made up few numbers and used a photo of Flinders street station I took when I was in Melbourne last year.

Imagine you have a worksheet with lots of charts. And you want to make it look awesome & clean.

Solution?

Simple, create an interactive chart so that your users can pick one of many charts and see them.

Today let us understand how to create an interactive chart using Excel.

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.

Last week, we had a lovely poll on what are your favorite features of Excel? More than 120 people responded to it with various answers. So I did what any data analyst worth his salt would do,

I analyzed the data and here are the top 10 features in Excel according to you.

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.

As you may new, the newest version of Excel is out for a while. I have been using it since last 6 months and enjoying it. Today, lets understand 10 things in 2013 that wowed me (and probably you too).

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:

1. 2 of my favorite festivals – Easter & Holi (a festival of colors, celebrated in India) are this week. Holi is today (Wednesday) & Easter on Sunday.
2. 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 🙂
3. 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.

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?

Turns out, this is not a difficult problem. In fact, this question is asked every day & answered using Advances vs. Declines chart.

You may have seen this chart in financial newspapers or websites. Shown above, Advances vs. Declines chart tells us how many items have advanced & how many have declined.

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.
