Econimist’s daily chart is a one of my daily data porn stops. They take interesting data sets and visualize in compelling ways. While the daily chart page is insightful, sometimes they make poor charting choices. For example, this recent chart visualizing how countries spend their money uses a variation of notorious bubble chart. Click on the chart to enlarge.

What is wrong with this chart?

Bubble charts force us to measure and compare areas of circles. Unless you have a measuring tape somehow embedded in your eyes and you are a walking human scientific calculator, you would find this task impossible.

So when you look at the chart and want to find out what percentage Japanese spend on restaurants or how much Americans pay for housing, your guesses will have large error margins.

Not only bubble charts are difficult to read, they are very hard to align. So when you have a bunch of bubbles, no matter how hard you try, your chart looks clumsy (see how the Russian food bubble eats in to Mexico’s bubble, as if it is too hungry 😉 )

Let’s check out a few alternatives to this chart. Read on…

I have an exciting announcement to share with you. My first ever print book – Dashboards for Excel, co-authored with Jordan Goldmeier is releasing on 15th September.

Dashboards for Excel – what is it?

As the name suggests this book is a handy guide for anyone preparing dashboards, management reports and business intelligence workbooks using Excel. The key benefits are,

• Learn the visualization tools, charts, tables, and graphs important to management.
• Understand what management doesn’t want to see in a report
• Turn around dashboards faster and cheaper than ever before
• Understand the key role dashboards play in an organization
• Analyze real-world dashboards to apply important features to your own organization
• Utilize understated, but powerful, Excel formulas and VBA code
• Avoid common pitfalls in Excel development and dashboard creation
• Get started with the Excel data model, PowerPivot, and Power Query

As you can see, this is an advanced Excel book with lots of examples, case studies and practical tips.

Cascading drop downs enhance usability of your dashboards & interactive workbooks. A cascading drop-down is a 2 or more level selection mechanism. When you have 100s of selection choices, instead of creating one massive drop down or combo-box, you can set up multiple levels of drop downs, so that users can narrow down their selection. For example, users can select Country, State and then City using cascading drop downs.

There are many ways to setup cascading drop downs. You can use formulas coupled with either data validation or form controls. You can also use Slicers. In this video we will review these techniques.

Pivot tables are very powerful analysis tools. They can summarize vast amounts of data with just few clicks. But they are lousy when it comes to output. Imagine the horror of putting a pivot table right inside your beautiful dashboard. One refresh could ruin the layout and create half-an-hour extra work for you.

How to combine the power of pivot tables with elegance of your dashboards?

The answer is: GETPIVOTDATA()

We all know the good old SUM() formula. It can sum up values in a range. But what if you want to sum up only filtered values in a range? SUM() doesn’t care if a value is filtered or not. It just sums up the numbers. But there are other formulas that can pay attention […]

Yesterday, you learned about Print Areas – a time & paper saving feature of Excel. While print areas are great, you can only set up one print area per sheet. What if you want to print either report or data based on user selection? 

In such cases, you can set up dynamic print areas. 

That is right. See above demo to understand how it looks. Read on to learn how to set up dynamic print areas.

Power Query offers many ways to get data to Excel. One of them is to Web Data import feature. Let’s understand how this works by importing world stock exchange closing data from Google Finance website.

Here is a best practice to improve your dashboard usability. If you have an interactive dashboard, highlight user selections thru conditional formatting.

Check out below quick video to understand what this means.

Here is a tricky problem often faced by accountants and finance professionals: Let’s say you have 5 customers. Each of them need to pay you some money. Instead of paying the total amount in one go, they paid you in 30 small transactions. The total amount of these transactions matches how much they need to pay you. But you don’t know which customer paid which amounts. How would you reconcile the books?

If you match the transactions manually, it can take an eternity – after all there are more than 931 zillion combinations (5^30).

This is where solver can be handy. Solver can find optimal solution for problems like this before you finish your first cup of coffee.

VLOOKUP is one of the most useful Excel functions. So much so that I even wrote a book about it. But it has one serious limitation.

It looks up the first occurrence and returns corresponding data.

What if you want to find the last value?

Say, for example, you are looking at a task assignment list and want to know what is the last task assigned to employee Emp13?

We want to extract the task “Make amazing workbook”. Of course our good old VLOOKUP stops once it finds Emp13 and returns the answer as “Create intuitive workbook”.

Analyzing top n (or bottom m) items is an important part of any data analysis exercise. In this article, we are going to learn Excel formulas to help you with that.

Let’s say you are the lead analyst at a large retail chain in Ohio, USA. You are looking at the latest sales data for all the 300 stores. You want to calculate the total sales of top 10 stores.  Read on to learn the techniques.

We, adults can’t escape three things:

1. Deadlines
2. Demanding bosses (replace with customers or nagging spouses or naughty kids)
3. Taxes

While I can’t help you with demanding bosses or taxes, when it comes to deadlines, I have the right tool for you.

A tracker that highlights all overdue items so that you know where to focus your attention.

Let’s learn how to use awesome powers of Excel to find-out which items are due. You can apply these concepts to nail down over due invoices, pending project tasks or scheduling workforce.

Sparklines are fun and very insightful. They are easy to create, easy to maintain and fit into any dashboard.

But there is one tiny problem with them. Usually we have a lot of data, but we don’t to visualize all of it. We just want to visualize latest 30 days trend or last 12 months trend or QTD or something similar. What then?

In this video, learn a powerful and very simple way to create dynamic sparklines using Excel.
