How To Use Hadoop With #Tableau and #Alteryx
We recently made a discovery that allows us to use Alteryx and Tableau with the IBM BigInsights Hadoop platform. This article describes how that happens.
Temperature Changes Over the Past 50 Years: A Visual Tour Country by Country
Three years have come down to this article. I now feel that I have a good grasp on the spatial and temporal changes in temperature over the past 50 years. I feel like I have now achieved one of my goals in doing this work.
Global Climate Data Set 2 – Monthly and Decade Average Temperatures
In this article, I give links to monthly aggregated temperatures, as well as decade aggregated results. These files are much smaller than the daily data files and should be easier for most people to render in Tableau or their favorite graphics package.
Global Climate Data Set 1 – Daily Temperatures
This is the first article of a series that will give download links to the processed global climate data sets I have developed. This article contains daily temperatures from monitoring stations around the world.
My #Alteryx17 Climate Change Presentation
June 6, 2017 was a great day for me. I was able to discuss three years of work with a room full of people at the Alteryx 2017 Inspire Conference. It was dream come true.
How To Achieve Better Data Comprehension, Part 3
It has taken me eight months to finish this series on achieving data comprehension. This is the third and final installment that explains how I have learned to be a data exploiter. You will need to read the article to find out what that means.
How I Use #Alteryx and #Tableau to Comprehend Climate Change
I presented this talk on May 4, 2017 in Austin, TX, at the Tableau customer summit. I want to say thanks to Brenda Akers for asking me to do this because it gave me a chance to share my work from the past few years.
A Nightmare on Excel Street
One night after getting frustrated with helping my son complete some Excel homework, my dreaming brain made me watch a movie called “A Nightmare on Excel Street”. You have to read the article to understand what that means.
Using #Alteryx and #Tableau to Visualize and Understand Population Density
Sometimes real work leads to auxillary work that is needed for another purpose. That was the case in this article in which I took a deep dive into computing and visualizing population densities across the US. The results were fascinating and made a good case to share in this blog.
A Descriptive and Predictive Study of North American Air Temperature Changes Using #Alteryx and #Tableau
In my continuing series of understanding air temperature changes over time, I go deep to develop predictive models of air temperature changes at over 3200 monitoring stations. Alteryx and Tableau simply were outstanding in allowing me to perform this work in a couple of nights.
Tableau vs Power BI – Summary to Date
This is a summary article that contains links to the Tableau vs Power BI series I have been working on. I also include some impressions about using the software tools in real-world situations.
How I Use #Tableau As A Search Engine
The vision formed 2 years ago. Many months of experimentation and testing went into completing the vision. You need to read the article to understand what I mean.
Test 5 of Tableau Vs Power BI: Pure Computational Speed
This is test 5 of a series that compares Tableau to Power BI. The purpose of this test is to see which program has a faster computational engine.
How #Alteryx And #Tableau Can Produce Word Clouds
It has taken me nearly 4 years and writing over 300,000 words to create a word cloud. The data processing behind this word cloud is pretty cool, too.
How to Draw Simulated Topographic Contours in #Tableau
This article presents a couple of techniques for drawing contour lines in Tableau. These are not simply connected polylines, but rather are simulated topographic lines represented by a series of points extracted from the mathematical surfaces used to represent topography.
