Hi everyone
some months ago I began modeling with fenics and I solved the heat equation using time-stepping algorithms. I visualized my solution simply by using "plot" e.g. plot(u) and for every time-step the new plot did "override" the old one.
Now, for some reason, however, whenever I do the same two plot-windows appear and the solution "alternates" between them which makes it difficult to observe.
So my question is, what's the reason for this sudden oddly behavior??
