Hi,
can anybody tell me how to get gridlines in a logarithmic plot?
i tried eg.:
loglog([1,10,100], [1,10,100])
grid(True)
but neither the grid is drawn, nor an error occur. When i make a linear plot, grid(True) works fine and draws the grid.
(win32, python 2.6, matplotlib 0.99)
Thanks

from matplotlib.pyplot import *
plot([1,10,100],[1,10,100])
grid()
yscale('log')
xscale('log')
works here.

sebastian.
thanks Sebastian,
you are right, your code works here too. But i don't get it work in my multi y-axes plot from the matplotlib examples (http://matplotlib.sourceforge.net/examples/axes_grid/demo_parasite_axes.html). Even with linear plots, i get no gridlines.
Any idea, whats wrong here?
minimal code example:
#######################
import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid.parasite_axes import HostAxes, ParasiteAxes
fig = plt.figure(1)
fig.clf()
#plt.grid(True)
host = HostAxes(fig, [0.15, 0.1, 0.65, 0.8])
fig.add_axes(host)
host.plot([0, 10, 100], [0, 10, 100], label='host')
host.grid(True) #?
host.yaxis.grid(True) #?
host.yaxis.set_scale('log') #?
plt.draw()
plt.show()

This is a bug in the axes_grid toolkit. As a matter of fact, gridlines
in rectlinear coordinate are not implemented yet.
Unfortunately, I don't see any easy workarounds.
You may use mpl's original axis artists, but some of the functionality
of axes_grid toolkit may be lost.
host.toggle_axisline(False)
host.yaxis.set_ticks_position("left")
host.yaxis.grid()
host.set_yscale("log")
With new spine support in mpl, I think a similar plot can be drawn
without using axes_grid toolkit.

Hi,
I have the same behaviour with LocatableAxes. HostAxes, ParasiteAxes and LocatableAxes depend on 'mpl_toolkits.axes_grid.axislines.Axes'. It must be the matter origin.
This another example should draw a grid but does not:
import wx
from wx import Frame
from matplotlib.backends.backend_wxagg import FigureFrameWxAgg, FigureCanvasWxAgg
from matplotlib.figure import Figure
from mpl_toolkits.axes_grid.axes_divider import LocatableAxes
fig = Figure((1, 1), 50)
axes = LocatableAxes(fig, [0, 0, 1, 1])
# axes.toggle_axisline(False)
axes.grid(True)
fig.add_axes(axes)
app = wx.PySimpleApp()
my_viewer = FigureFrameWxAgg(-1, fig)
my_viewer.Show()
app.MainLoop()
If you uncomment axes.toggle_axisline(False), it works cause it uses normal 'matplolib.axes.Axes' behaviour. It is not a matter for common use but if you need 'AxesZero', this trick does not work.

Yes, and this was because I forgot to implement some necessary methods.
This is now fixed in the svn trunk. So if you can,please give it a try.

from matplotlib.backends.backend_wxagg import FigureFrameWxAgg,

axes = LocatableAxes(fig, [0, 0, 1, 1])
# axes.toggle_axisline(False)
axes.grid(True)
fig.add_axes(axes)app = wx.PySimpleApp()

app.MainLoop()If you uncomment axes.toggle_axisline(False), it works cause it uses
normal 'matplolib.axes.Axes' behaviour. It is not a matter for common
use but if you need 'AxesZero', this trick does not work.
What the toggle_axisline does is simply to make the xaxis and yaxis
(which are responsible for drawing ticks, ticklabels, etc in the
mainline mpl) visible again, and make axis["bottom"] and etc
invisible.
One workaround is to make xaxis and yaxis visible but pnly to draw the
gridlines. Something like below.
ax.toggle_axisline(True)
ax.grid(True)
ax.gridlines.set_visible(False) # this is just to make the code not to
draw gridlines twice in future release of mpl.
ax.xaxis.set_visible(True)
ax.yaxis.set_visible(True)
for t in ax.xaxis.majorTicks + ax.yaxis.majorTicks:
t.gridOn = True
t.tick1On = False
t.tick2On = False
t.label1On = False
t.label2On = False
Let me know if this does not work, or there is a case that this cannot be used.

I can not try your revision but I will do it as soon as it is released.
Nervertheless I try your snippet with an AxesZero. I get the gridlines and the axis but the first was over the second. It is not what I expected.
As far as I am concerned, I can wait until matplotlib next release.
Thanks,

You can rearrange the order of artists by setting the zorder.
As far as I am concerned, I can wait until matplotlib next release.
Just to clarify, the patch will be included in the 1.0 release, not
the maintenance release of 0.99 version.

Hi,
is it enough to overwrite the axesgrid.py file in my matplotlib 0.99 installation with the file from svn? I tried that, but i see no effects. Are there anywhere precompiled matplotlib releases for 1.0_win32_pre?
