I'm trying to plot the curve of an exponential distribution without much success. I'm missing something very basic I feel, but just can't figure it out after numerous tries, so I'm turning out to you.This is the function generating the frequency of individual outcomes: import decimal from random import expovariate from collections import defaultdict decimal.getcontext().prec = 4 Dec = decimal.Decimal samples = 100000 # 100,000 def generate(lambd): res = defaultdict(int) for _ in range(samples): res[Dec(expovariate(lambd)).quantize(Dec('0.01'))] += 1 return res Trying to plot this data into a frequency curve is proving too challenging and I just can't understand why. plot(list(results.keys()), list(results.values())) This results in strange line graph where there is the outline of an exponential curve but the line crisscrosses all over the place. I can't understand why I am getting this graph result and not just the smooth line I can infer from looking at the hard data.
Anything that can hep you here http://matplotlib.org/gallery.html#statistics ?
