.transpose and plot
- This will set the column headers as the index, and make it possible to plot them on the x-axis.
# transposed dataframe nfl.T

# plot a transposed dataframe
nfl.T.plot.bar()

For a histogram of all the values
- I recommend using seaborn, which is a high-level API for matplotlib.
- It makes working with different shapes of data, easier.
seaborn.distplot
import seaborn as sns
# plot
p = sns.distplot(a=nfl, kde=False)
p.set_xlabel('bins')
p.set_ylabel('counts')
