Interactive Decision Tree Visualization in Excel [Trump vs. Hillary in Swing States]

Interactive Decision Tree Visualization in Excel [Trump vs. Hillary in Swing States]

It is election time in USA, and that means there is a whole lot of drama, discussions and of course data analysis. There are tons of cool visualizations published on all the data. Previously, we talked about “How Trump happened” chart.

Today let’s take a look at the beautiful decision tree chart by NY Times explaining what would happen if each of the 10 swing states vote for Democrats or Republicans. Go ahead and look at that chart. And when you are done playing with it, come back.

My first thought after looking at the chart is: Wow, that is cool. I wonder how we can recreate that experience in Excel?

But as you can guess, making a dynamic tree visualization in Excel is pretty hard. You can create a bubble chart mixed with XY chart to show all the nodes of the decision tree, but as this tree has 2^10 nodes at the bottom level (and 2^11-1 total nodes) our chart would look very clumsy and busy.

So, instead of replicating NY Times chart, why not make our own version that explains the data? You can reuse this idea when visualizing outcomes of several what-if scenarios.

Currency format Pivot fields with one click [Friday VBA]

Currency format Pivot fields with one click [Friday VBA]

Anyone who has made a pivot table and their grandma knows that formatting them is a pain. Let’s recap the steps to apply one of the most common formats – currency format.

  1. Right click on any value field
  2. Go to Value field settings
  3. Click on “Number Format” button
  4. Choose Currency format
  5. Close the boxes, one after another

Unless you get paid per click, you wont be happy with all those clicks.

Wouldn’t it be cool to just click once and apply most common format to your pivot fields?

Of course you can. Just add oneClickCurrency macro to your personal macros workbook. And then add this to your Home ribbon as a custom button and you have a one click format option for any pivot.

Teach coding to your kids with this maze game [VBA]

My twins (Nishanth & Nakshtra) are now almost 7. They are super keen to learn how computers work. So the other day, I showed them Code.org where there are several coding exercises disguised as games. They loved those games … err coding exercises. So that got me thinking… why not make a game in Excel that teaches kids simple programming concepts.

So I built a Snowman & Hot Chocolate Maze game. In this post, let’s understand how to build such a game using Excel VBA.

Today is Diwali, the festival of lights. I wish you and your family a happy, bright and prosperous festive time. May your house shower with lots of light, laughter and love.

This year, my kids (who are 6 yrs btw) are very excited about the festival. They are looking forward to lighting up diyas and crackers (fire works).

Quickly filter a table by combination of selected cell values using VBA

Published on Jul 15, 2015 in VBA Macros
Quickly filter a table by combination of selected cell values using VBA

Filtering is one of the most used feature in Excel. It is a quick way to take lots of data and narrow down to the subset we want.

But here is one common filtering scenario that is slow as snail.

Imagine you are looking at some sort of sales data (if you can’t imagine, look at the above demo).

Now, you want to filter this list for gender=male, profession=self-employed, product category = chocolates and  quantity = 1.

If you use the right click, filter > filter by selected value approach, this will take several clicks.

Wouldn’t it be cool if you can select the entire combination and say filter?

Unfortunately, no such feature exists in Excel.

But you are not aiming to be ordinary in Excel.  You are aiming to be awesome in Excel. That means, you don’t take no for answer.

Fortunately, we can quickly write a VBA macro that filters a list by selection. So let’s do that.
