title: Multiple Plots in Mayavi
body: <p>MATLAB has a <code>hold</code> function (if I remember correctly, it's been a while) to plot several things on the same "graph"/window. Is there anyway to do this in Mayavi? I'd like to visualize several realizations of a calculation, and have them all on the same graph. But I haven't been able to figure it out from reading the documentation.</p>
