* This visualization code is rather crude, in the sense that it's a direct overlay on top of the Spavisual window. We're just computing the coordinates of a line and inserting it into an existing figure. There is no interaction with the Spavisual buttons. So, make sure that the eigenmode you're viewing in Spavisual is the same as the mode that you plotted the rotation axis for. | * This visualization code is rather crude, in the sense that it's a direct overlay on top of the Spavisual window.
