If I run the following lines of code I get a nice scatter plot of two variables from the dataframe with the dateseries visualized using color over the scatterplot using a colormap. So I also add the colorbar:

import pandas
import numpy
import matplotlib.pyplot as plt

dates = pandas.date_range('1/1/2000', periods=8)
df = pandas.DataFrame(randn(8, 2), index=dates, columns=['A', 'B'])
plt.scatter(df['A'],df['B'],c=df.index)
plt.colorbar()

and you get the following output:

I would like to display the dates as dates rather than integers in the colorbar. I've tried to run the following:

import pandas
import numpy
import matplotlib.pyplot as plt
import matplotlib

dates = pandas.date_range('1/1/2000', periods=8)
df = pandas.DataFrame(randn(8, 2), index=dates, columns=['A', 'B'])
plt.scatter(df['A'],df['B'],c=df.index)
plt.colorbar(format=matplotlib.dates.DateFormatter('%b %d %Y'))

but I get this error:

OverflowError: signed integer is greater than maximum

Is anyone else working with the Yelp API? I was working with one of your classmates today and we ran into a problem we couldn't figure out. The "offset" parameter doesn't seem to be working when we use it in the URL request. The "limit" parameter works as expected even with identical syntax.
