Create 3d plots in loop, noninteractive

[wagmanbe]

Hi, I'm trying to loop over time, making 3d_scalar plots and exporting them. This works in 2D (see simple 2d data animation). But in 3d, the plots are identical and never advance in time, even though the data is different. I have tried to get creative about not reusing canvas names, and clearing everything I can, to no avail. Here's an example of what I'm doing. I haven't attached any data so this is just a hypothetical. Perhaps this is a bug?
