Direction of tick marks in matplotlib

Is there a way to make the direction of the tick marks on the bottom of the xaxis point outward, but the top ones point inward, using matplotlib?

Yes! You can use the set_tick_params() method to do this. Here's an example for setting up a histogram to work as you described:

hist.xaxis.set_ticks_position('both')  # Adding ticks to both top and bottom
hist.xaxis.set_tick_params(direction='in', which='top')  # The bottom will maintain the default of 'out'

You can change the ascending/descending order of tick marks by passing in limits for the x and y-axes that decrease.

I.E. to make the x-axis go from 10 to 0, instead of 0 to 10 and the y-axis to go from 10 to -10, you can do:

plt.xlim(10, 0)
plt.ylim(10, -10)

Here is an example from matplotlib demonstrating this functionality on a simple case.
