How to make several plots on a single page using matplotlib?

I have written code that opens 16 figures at once. Currently, they all open as separate graphs. I'd like them to open all on the same page. Not the same graph. I want 16 separate graphs on a single page/window. Furthermore, for some reason, the format of the numbins and defaultreallimits doesn't hold past figure 1. Do I need to use the subplot command? I don't understand why I would have to but can't figure out what else I would do? ``` import csv import scipy.stats import numpy import matplotlib.pyplot as plt for i in range(16): plt.figure(i) filename= easygui.fileopenbox(msg='Pdf distance 90m contour', title='select file', filetypes=['*.csv'], default='X:\\herring_schools\\') alt_file=open(filename) a=[] for row in csv.DictReader(alt_file): a.append(row['Dist_90m(nmi)']) y= numpy.array(a, float) relpdf=scipy.stats.relfreq(y, numbins=7, defaultreallimits=(-10,60)) bins = numpy.arange(-10,60,10) print numpy.sum(relpdf[0]) print bins patches=plt.bar(bins,relpdf[0], width=10, facecolor='black') titlename= easygui.enterbox(msg='write graph title', title='', default='', strip=True, image=None, root=None) plt.title(titlename) plt.ylabel('Probability Density Function') plt.xlabel('Distance from 90m Contour Line(nm)') plt.ylim([0,1]) plt.show() ```
