I have a scatter plot graph with a bunch of random x, y coordinates. Currently the Y-Axis starts at 0 and goes up to the max value. I would like the Y-Axis to start at the max value and go up to 0.
points = [(10,5), (5,11), (24,13), (7,8)] x_arr =  y_arr =  for x,y in points: x_arr.append(x) y_arr.append(y) plt.scatter(x_arr,y_arr)
There is a new API that makes this even simpler.
DisplacedAussie's answer is correct, but usually a shorter method is just to reverse the single axis in question:
plt.scatter(x_arr, y_arr) ax = plt.gca() ax.set_ylim(ax.get_ylim()[::-1])
gca() function returns the current Axes instance and the
[::-1] reverses the list.
