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.
