Hi Eric,
you are right that there is no documentation about this and maybe I'm the only
guy how thought that this functionality is included. There were actually 2
threads, on which I proposed this as part of a solution: "[Matplotlib-users]
problem with minorticks" from end of march 2010 and the thread "[Matplotlib-
users] Turning off minor grids on log scaled plot" of april 2010, where the
latter gave the starting point for the later proposed patch.
I'm sorry for causing this confusion and wasting your time.
Nontheless thank you for fully including the possibility to change both major
and minor ticks at the same time.
Kind regards,
Matthias

I think that behavior would indeed drive the user crazy, so I would not
want to commit a patch that does that.

The docstring for Axis.grid used to say
Set the axis grid on or off; b is a boolean. Use *which* =
'major' | 'minor' to set the grid for major or minor ticks.
This is pretty clear--*which* is 'major' or 'minor', not a string that
might contain either or both. How would a user have gotten the idea
that the API included 'majorminor'? Was it documented somewhere else?
Granted, because it was written using a string search to parse the
kwarg, any string containing major and or minor would work, but this
strikes me as a bad API, and not in keeping with the rest of mpl. Given
the docstring, I suspect that the behavior was actually accidental.
Both the code and the docstring have been the same since at least
2004--I got tired of tracing it back in time. In this case I am
inclined to make the behavior consistent with the docstring, and then
enhance it with the "both" option, as I did.
Was there a mailing list thread pointing out that "majorminor" etc would
actually work, contrary to the docstring?

Hi Eric,
thanks a lot for this commit. This is exactly what I wanted.
There is only one thing about the new possibilities 'both', 'minor', or
'major'. The first possibility replaces 'majorminor', 'minormajor',
'some_string_including_major_and_minor', ... and I'm afraid that this could
break someone's code.
Kind regards,
Matthias

The first patch adds the keyword argument 'which' from the axis.grid to

This yields the expected behavior if e.g. all (major and minor) tick
grid lines are shown, because than toggling the grid means to remove
all grid lines. But to be honest I'm not sure the latter is the
intended behavior in all cases. For instance in the case of shown major
tick lines toggling all means turning off major tick lines and turning
on minor tick lines by pressing 'g'. This sounds a little bit crazy to
me, although that's what toggling is about.

in mind. The which kwarg can be 'both', 'minor', or 'major'.

Hi Eric,
thanks a lot for your comment. What do you think about the first part namely
adding the kwarg 'which' from the axis method to the Axes method grid?

Hello list,
Does anybody think the proposed patches could be useful?
If somebody would benefit from them I'd be happy to place an updated version of
the patch(es) at the patch tracker.
Thanks in advance for any comments.

[Matplotlib-users] patch: adding kwargs 'which' in axes.grid and 'g' toggles all tick grid lines
Hello list, Hello developers,
I'd like to summarize my discussion with Gökhan ("Turning off minor grids on
log scaled plot") in the last days and propose two patches.
The first patch adds the keyword argument 'which' from the axis.grid to the
method 'grid' of the Axes (axes_grid_for_major_and_minor_ticks.patch). This
allows to change the drawing of grid lines for x- and y-axis at the same
time.
Furthemore Gökhan proposed to toggle *all* (namely major and minor tick) grid
lines after pressing the key 'g'. Therefore the call event.inaxes.grid(),
which toggles only the (default) major tick grid lines, is replaced by
event.inaxes.grid(which='majorminor') (see
toggling_all_tick_grid_lines.patch).
This yields the expected behavior if e.g. all (major and minor) tick grid
lines are shown, because than toggling the grid means to remove all grid
lines. But to be honest I'm not sure the latter is the intended behavior in
all cases. For instance in the case of shown major tick lines toggling all
means turning off major tick lines and turning on minor tick lines by
pressing 'g'. This sounds a little bit crazy to me, although that's
what toggling is about.
Thanks in advance for any comments.
Kind regards,
Matthias
