Congratulations if you managed to get past the title! That means that you have at least a passing interest in mathematics. I don’t know where the idea came from, but I thought it would be a nice exercise to work out the prime factors of numbers using sets in Tableau. I had also wanted to experiment with designing for mobile and modern UI trends, so I brought all these ideas together into one dashboard. You can see it here. Techniques…
The theme of this month’s IronQuest was games. After my last couple of projects, I had promised myself not to spend too long on this one. I failed miserably! So this will be a story of failures and lessons learnt, plus some highlights of the final dashboard at the end. See the result here Lessons learnt, all about what you can’t do in Tableau Public: ● No access to APIs● No access to any live data● No way to programmatically…
You can see my entry here. Lessons Learnt ● I spent far too long on this! I’ll try to take a much simpler approach next time. ● It is difficult to balance background images that cover the whole dashboard with visual clarity. Not sure of the best solution here. To be practised. Or maybe avoided. ● More to come after feedback! Makeover Monday Whilst I deeply love playing with mathematics and geometry in Tableau, I’ve felt a bit weak on…
I was inspired to create this dashboard by the amazing videos of NASA’s Perseverance Rover surviving the “Seven Minutes of Terror” during it’s landing on Mars. If you saw it, you probably noticed that the parachute had a rather strange pattern on it. It turns out that that was one of many easter eggs included in the mission. The parachute encoded the Jet Propulsion Lab’s motto “Dare Mighty Things” along with the coordinates of the Lab itself. “Super nerdy”, I…
I didn’t manage to finish my “What’ the Harm?” dashboard in time for #IronQuest or with any degree of polish, but I did manage to come up with a new (at least for me) chart type: the hex spiral unit chart. I’m not sure it has that much data visualisation value, but it looks kind of pretty! This article describes how to build one: Background and alternative approaches For my What’s the Harm dashboard, it was critical for me that…
Lorna gave us another challenge today based on the geo calculations in Tableau. Challenge PageLorna’s solution on publicData for the challengeMy solution on public The challenge is to create a map of crimes in London and filter and colour them according to their distance from a selected central point, either St. Paul’s Cathedral or Buckingham Palace. It was mostly pretty straightforward, except for a couple of dumb mistakes I made, which had nothing to do with the crux of the…
This is the third in my series about how I built my animated dashboard about Fourier Series: By the end of the last post, I had built up the SIN wave graph (bottom-right in the dashboard) and the waterfall chart (not visible above). In this post, I’ll go through the steps for creating all of the elements in the main graph at the bottom of the dashboard, which I simply called “Circles”. The components of this can individually be turned…
This is the second in my series about how I built my animated dashboard about Fourier Series: Seeing the SINs The basis and indeed the whole point of the dashboard are the calculations needed for the SIN graph. Here shown for the square wave: The whole idea with a Fourier series is that different SIN waves, all at different frequencies and amplitudes according to the equation below, add up to form a square wave with an amplitude of 2 (-1…
This is the first entry in this series Making waves with Fourier Series, Part 1 Making waves with Fourier Series, Part 2 As you will have seen from some of my previous posts and dashboards, I rather like combining maths and Tableau. That was the main motivation form the 3d rotating cube. This time I was inspired by a video about visualising how Fourier Series work by Destin Sandin on his Smarter Every Day channel. Click on the screenshot below…
A fun little challenge this week from Luke. It was one of those where if you hadn’t already worked with certain concepts, it would be really difficult, but not too bad if you had. Fortunately, I had and when I saw the challenge, I knew I wouldn’t have too much trouble (in principle!) It also had the benefit, that the difficulty was in the concept, so it’s pretty quick to build if you already know the techniques. In essence, this…
