Space-time plot added to web lab

Space-time plots are a beautiful way to view dynamic reaction-diffusion systems. We added one to the Web Lab, “Dynamic diffusion and reaction in a porous solid catalyst.” Here is a static screen shot from the lab.

Adding this dynamic plot required learning how to program the HTML5 canvas element with Javascript – an exciting combination!

We prepared static plots of space-time data for our previous research work, e.g., at We were inspired to make them dynamically by the fluid dynamics simulations of Oliver Hunt at and Daniel Schroeder at Those pages showed us that this was possible to do in a web page.
