Dynamically add subplots in matplotlib with more than one column

Question

How can I dynamically add a new plot to bunch of subplots if I\'m using more than one column to display my subplots? This answers this question for one column, but I cant se

Assuming at least 1 dimension of your grid and the total number of plots is known, I would use the gridspec module and a little bit of math.

import math

import matplotlib.pyplot as plt
from matplotlib import gridspec

def do_plot(ax):
    ax.plot([1,2,3], [4,5,6], 'k.')


N = 11
cols = 3
rows = int(math.ceil(N / cols))

gs = gridspec.GridSpec(rows, cols)
fig = plt.figure()
for n in range(N):
    ax = fig.add_subplot(gs[n])
    do_plot(ax)

fig.tight_layout()
