subplots with no space between limited to 6x6?

Community matplotlib-users

Hi, I'm trying to make a large grid of subplots with no spacing between. The
following code fails for any grid size larger than 6x6 by skipping a row and
a column.

for i in xrange(1,65):
    subplot(8,8,i)
    plot( [0,1] )
    subplots_adjust(hspace=0,wspace=0)

Is there a way around this problem?

Thanks,
Adam

Yes, I can reproduce this with the current svn.

I think what's happening is that, with larger number of grid, there
is slight overlapping between each subplots (likely due to the
floating point error). Note that subplot command deletes existing axes
if they overlap with the new one.

There would be several work-arounds. You may use non-zero spacing, eg,
0.001 worked for me. Or, you may manually add subplots to the figure
to avoid any deletion of existing axes.

from matplotlib.axes import Subplot

fig = gcf()

subplots_adjust(hspace=0.,wspace=0.)

for i in xrange(1,65):
    ax = Subplot(fig, 8, 8, i)
    fig.add_subplot(ax)
    plot( [0,1] )
