Trying to plot multiple lines on one graph using matplotlib and for loops, but the code doesn't work after the first iteration. Here's the code:

```
import csv
import matplotlib.pyplot as plt
r = csv.reader(open('CrimeStatebyState.csv', 'rb'))
line1 = r.next()

def crime_rate(*state):
    for s in state:
        orig_dict = {}
        for n in range (1960,2006):
            orig_dict[n] = []
        for line in r:
            if line[0] == s:
                orig_dict[int(line[3])].append(int(line[4]))
        for y in orig_dict:
            orig_dict[y] = sum(orig_dict[y])
        plt.plot(orig_dict.keys(), orig_dict.values(),'r')
        print orig_dict.values()
        print s

crime_rate("Alabama", "California", "New York")

```

Here's what it returns:

```

Why am I getting zeroes after the loop runs once? Is this why the other two graphs aren't showing up? Is there an issue with the sum function, the "for line in r" loop, or using \*state?

Sorry if that's not enough information! Thanks to those kind/knowledgeable enough for helping.
