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.
At first glance, you wouldn’t think that Andy Kriebel and the Chicago Bears have anything in common. Then again, you would be wrong. Read the article to find out why.
The Desmos graphing calculator is a very nice tool. If you have kids that are learning math, this is something that you need to show them how to use.
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.
The VizPainter has delivered another masterpiece. This trail-blazing Tableau master used a shape file that had a time series history of the United States to win the most recent Iron Viz Competition against some amazing Tableau artists.
Introduction This is a story from today as my wife Toni and I were driving overnight from Knoxville, TN to Charleston, SC to hop on a cruise. At 2 am.or so, I looked over at her to tell her a story. This is how it went… Ken: There are about 101,000 weather monitoring stations around…
This is test 6 of a series that compares Tableau to Power BI. The purpose of this test is to compare and contrast each program’s ability to read and work with shapefiles.
One day I heard a guy say that his brother had to wear “adult braces” after getting cracked in the mouth. Adult braces, I wondered, as I stood there as an adult wearing braces! I thought to myself that braces are braces, no matter how old you are when you are wearing them. They can hurt but they do great things for your smile. Hence, this article was born.
This is a fun article. I created a Tableau dashboard that allows us to view 55 years of temperature data to see if global warming is impacting where we live. When you spend a little time using this tool, you will have a better appreciation of the variability of weather and the difficulty of concluding anything about global warming.
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.
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.
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.
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.
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.
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.
