Bug report

Bug summary

I want to make rotate a 3D plot using theview_initmethod. If theazim argument is used it makes a smooth rotation around the z-axis. However, if theelev argument is used the plot is flipped after the angle 270 degrees. This problem seems to come from the fact that the range [0:-90] does not give the same output as the range [270:360] while it should. Here are two outputs that should be the same for -15 and 345, but there are not.

Code for reproduction
