Perhaps because my data covered a large range 10**-7 ... 10**0? I'll try some experiments. I had to force it with: fig.get_axes()[0].set_yticks ([a*(10**b) for b in xrange (-7,0) for a in xrange (1,10) ], minor=True) > In [2]: plt.gca().yaxis.minor.locator._base > Out[2]: 10.0 > >> 2) I'd like the major ticks to be solid lines, and minor ticks >> to be dashed.
