Hi Gökhan,
I can confirm your findings and I hope my attached patch (against current svn)
solves this problem. In the axes.grid the boolean 'b' was set to 'True' if
the kwarg 'which' was suplied, because it was part of the **kwargs and so
always b was True in the axis (e.g. ax.xaxis).
Now I get a grid on the minor-ticks by calling:
ax.grid(True, which="majorminor")
and remove the the minortick-grid lines / all grid lines by calling
ax.grid(False, which="minor")
ax.grid(False, which="majorminor")
Kind regards,
Matthias
