Re: [Matplotlib-users] logarithmic plotting and the grid

[Lee B. <Bog...@ca...>]

I think he wants to turn the grid on for both major and minor ticks. I'm 
interested in that also. Is there a way to do that?

grid takes an optional argument "which". Unfortunately this is not
properly documented with pylab.grid and Axes.grid.
But see

http://matplotlib.sourceforge.net/api/axis_api.html?highlight=grid#matplotlib.axis.Axis.grid


grid(True) # this turns on gridlines for major ticks
grid(True, which="minor") # this turns on gridlines for minor ticks.
