Animated Hypocycloid Charts
A companion file is available: Click here to download
With a few simple macros, you can creating some interesting animation effects in charts. For example, I created a workbook that displays an infinite number of dazzling animated charts. The workbook is set up with a simple user interface that makes it very easy to generate a new chart or save the parameters for charts that you like. Turn animation on or off with the click of a button.
The chart displays what's known as a hypocycloid curve -- the path formed by a point on a circle that rolls inside of another circle. This, as you may recall from your childhood, is the same technique used in Hasbro's popular Spirograph toy.
The workbook is not protected, so you can view the formulas and VBA macros that are used.
