With the PGA Championship wrapping up another year of Major Golf Tournaments and the very young Rory McIlroy dominating the field, it occurred to me to ask: "Is winning a major only for the young players?" Also, despite Tiger Woods' recent back surgery and sudden...

The highlight table allows us to apply conditional formatting to a view. Tableau will automatically apply a color scheme in either a continuous or stepped array of colors from highest to lowest. It is great for comparing a field’s values within a row or column. In...

To take a more visual approach to showing data than we might typically see in a crosstab, let’s consider a heat map. A heat map is a great way to compare categories using color and size. In this, you can compare two different measures. In...

Not everyone is a Tableau guru, at least not yet. To help Tableau rookies, we’re starting from square one with the Tableau Essentials blog series. The series is intended to be an easy-to-read reference on the basics of using Tableau Software, particularly Tableau Desktop 8.1...

Let it be duly noted that I used the euphemistic term rather than the pejorative “patent troll”. +1 for me!  What is Patent Trolling? When an issue makes to the Office of the President of the United States, you know it’s gotten big. Patent trolling, or using patents to...

Last week, I had the opportunity to attend the Alteryx Inspire 2014 conference in San Diego. The show was well-presented by Alteryx and conveyed a very consistent message of “data for the people.” I’ve attended many conferences over the past 25 years, and I have to...

There are people living in America today who did not have electricity in their home growing up. It cannot be overstated how much the power industry has changed since then. To understand and communicate those shifts, we turn to data. Some have done an outstanding...

So many times in history one person's valuable contribution ends up being eclipsed by another for no good or fair reason. Think of Galileo, who was not (and never claimed to be) the inventor of the refracting telescope - it was invented by Dutch spectacle makers....

Most data analysis is concerned with understanding what the data tells us - for example understanding if business is growing or not and discovering how sales are developing in different territories or across product lines. But sometimes the story the data is not telling can be...

Do I have a healthy pipeline of sales opportunities? Ensuring a healthy pipeline of opportunities is a key concern of any Sales Manager. In this post I would like to share with you a way of visualizing your pipeline that has proven highly valuable in practice....

Before we can attempt a Marimekko, we need to understand a few of Tableau's lesser used tools. The first of these is the Polygon mark type which can be selected from the dropdown on the marks card. Since the Marimekko is actually made up of lots...

In Part 1 we learned how to use custom SQL to shape our data ready for use later on in polygons. In this part we will use parameters to allow dashboard viewers to exchange dimensions. This methodology can be applied to any chart type which is sliced...

In Part 2 we simulated a Marimekko using stacked bars but since the boundary for each element / polygon of a Marimekko in Tableau is made up from 4 Cartesian Coordinates we are going to use scales of 0 – 100 % for both X and Y...

In Part 3 we created all the calculated fields necessary for our basic Mekko. Because we have preset the DTC (Direction of Table Calculation) for each calculated field we can simply drag them on to the view to create the mekko and be confident that the values...
