While there are certain differences, most of the usual matplotlib command
supposed to work. So, I recommend you to read the matplotlib documentation
first.
1. There are lots of examples in the gallery. Please take a look.
2. see the code below.
3. this kind of thing is difficult to do with axes_grid toolkit. but see
below.
First, you need to change the x-values to date (not seconds).
Then, add the code below inside your for loop.
Other than ax.axis["bottom"].. thing, these are just normal matplotlib
command.
Also, I should have mentioned it earlier, but I don't see any need of
axes_grid toolkit in your code. You'd better simply use subplot, which is
recommended if you're not familiar with matplotlib.

ax = my_grid[i]
ax.autoscale_view(tight=True) # adjust xlim and ylim
# you can manually call ax.set_xlim and ax.set_ylim.
ax.xaxis_date() # tick format as date and time
ax.axis["bottom"].major_ticklabels.set_rotation(30)
ax.axis["bottom"].major_ticklabels.set_ha("right")
ax.axis["bottom"].major_ticklabels.set_va("top")
# with axes_grid toolkit, it is difficult to make a certain
# ticklabel invisible (without disabling the tick line). The
# below line of code slightly adjust the ylim so that y=0 ticks
# are not shown
ax.set_ylim(ymax=-0.001)
