We analysts like to compare. If you ever want to keep an analyst busy, just give her 2-3 options. She won’t return to your desk until the cows come home. My wife uses this trick all the time. Picture this:

[In late 2013]
Me: I want to buy a new phone
She: Do you want Nexus 5 or Galaxy S5 or iPhone 5s?

Its late 2014 and I am not done comparing.

So today, let’s talk about an interesting comparison scenario.

Comparing by letter or word

See above demo to understand the concept. Read more to learn how to do this.

Recently, I saw this chart on Economist website.

It is trying to depict how various cities rank on livability index and how they compare to previous ranking (2014 vs 2009).

As you can see, this chart is not the best way to visualize “Best places to live”.

Few reasons why,

• The segregated views (blue, gray & red) make it hard to look for a specific city or region
• The zig-zag lines look good, but incredibly hard to understand % changes (or absolute changes)
• Labels are all over the place, thus making data interpretation hard.
• Some points have no labels (or ambiguous labels) leading to further confusion.

After examining the chart long & hard, I got thinking.

Its no fun criticizing someones work. Creating a better chart from this data, now thats awesome.

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?

Hola folks…

My trip to Houston & Dallas was very successful, fun & awesome. I got back home on Friday and instantly I am in another fun, awesome & happy place with my kids, Jo (my wife), rest of the family & friends.

Today, I want to share a very simple yet super awesome trick with you. I learned this from Augie, one of the Houston Masterclass participants.

You can drag slicer items to multi-select them.

Selecting multiple items in a slicer quickly

We know that slicers are powerful, friendly and fun way to filter the pivot tables, pivot charts, power pivot tables and regular tables (only in 2013). They are visual filters that can be used to instantly filter the data (or report). But when it comes to selecting multiple items, slicers can be hard. We must hold CTRL key and tap multiple slicer items one at a time to select them. At least that is how I used to do it.

Do you know we can drag to multi-select?

Here is a quick tip to start the week.

Often, we end up with a situation where a bunch of numbers are stored as text.

In such cases, Excel displays a warning indicator at the top-left corner of the cell. If you click on warning symbol next to the cell, Excel shows a menu offering choices to treat the error.

Today, lets learn how to create an interesting chart. This, called as network chart helps us visualize relationships between various people.

First take a look at what we are trying to build.

Looks interesting? Then read on to learn how to create this.

Today, lets learn how to make a simple timer app using Excel. First some background…,

Recently, I learned how to solve Rubik’s cube from my nephew. As a budding cuber, I wanted to track my progress. Initially I used the stopwatch in my iPhone. But it wont let me track previous times. So I thought, “Well, I can use Excel for this”.

So I made a small timer app using Excel. Its quite minimalistic. It has a single button. I press it and it tracks the start time (date & time stamp). If I press the button again, it records the duration.

This way, I can see my progress over next few weeks and may be plot the trend.

Last week we learned how to answer questions like, “How many tiles in a room?” using Excel. We learned about CONVERT function and fraction number format settings in Excel.

But why stop at calculation? We can even model a room full of tiles, thanks to Excel’s grid nature.

So today, we will learn how to create a room layout as shown above, using Excel.

In the 4th session of Chandoo.org podcast, lets talk about Pie charts.

Pie charts evoke strong opinions among analysts & managers. Some people love them and can’t have enough of them in reports. Others despise them and go to any lengths to avoid them. And that is why we are going to talk about them in this session.

You will learn,

• Special, secret transmission from guest stars
• What is a pie chart?
• Why they work? 2 reasons
• Why they don’t work ? 4 reasons
• Cousins & siblings of Pie charts
  • Donut charts
  • Gauge charts (speedometer)
  • 3D pies
  • Area charts
  • Bubble charts
• 4 Situations when making a pie chart is ok
• Alternatives to Pie charts
• Mistakes you should avoid
• About the resources
• Conclusions

One of the most useful features of Excel is formula help box. You know the little yellow box that appears as soon as you start typing a formula in a cell. I use this all the time to understand what the syntax of a particular function is, what parameters to pass etc.

Although I love it, sometimes it does get in the way when writing formulas. Because the help box sits on top of my data, often I find it hard to know which cell to link to.

Solution?!?

Simple. Use your mouse to move away the help box wherever you want.

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

Gantt charts are a very popular way to visually depict project plans. Today, let us learn how to use Excel to make quick & easy Project Plan Gantt Chart.

This is what we will be creating.

Ever wondered how to go from a bunch of cells with text to one big combined text? Like shown above.

Well, there is a simple trick. One of our readers, Grant shared this with us. Read on to learn this.

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.

You have been there. You are looking at a complex workbook with some hidden rows /columns. You want to know what is in that hidden cells. Alas, the worksheet is protected.

It is like the special coffee machine on top floor reserved for senior executives. You know it is there, but you cannot get to it. Now what?!?

Simple. Follow this process.

(I am talking about hidden cells, not the coffee machine.)
