Description

I am creating the attached plot like this:

fig, axes = subplots(3,3, sharex=True, sharey=True) for ch in range(1,7): axis = axes.flatten()[ch-1] cols = some code to map ch to col_names df[cols].plot(ax=axis)

do the same for 3 more channels with different IDs

for ch in range(1,4): axis = axes.flatten()[ch-1+6] cols = some code to map ch to col_names, slightly different to above df[cols].plot(ax=axis)

I have 2 problems with the result:

1. sharex does not seem to work for time axes
2. The last major x-ticklabel of the last row of axes is 10:00, while for the first 2 rows it is 9:00. I confirmed that all columns have data in the last row (index = 2011-04-02 10:00:00.718000) and not NaN which would have been excluded in the plot, potentially.

Possibly the 2 probs are related?
