when I zoom in the grid falls on odd values, like 0.385V, 0.889V, 1.393V, etc. I would have expected that "auto-arrange axes" would place the grid on more rounded values, starting with the 0V level, but that doesn't seem to do anything. To me the 0.889V line is useless, while for instance 0.900V might be useful. I guess this should be feasible based on the range shown in the window. I wouldn't even mind if the 0.889V grid line would be moved all the way to the 1V level.
