Pandas, Histogram Plotting With Subplots Based on Column Values

Question

I have a panda data table that looks something like this:

And it goes on through over a ton of rows. There's something like 30 or 40 different properties that I want to look at individually.

I'm looking to create a histogram for each individual property based on duration. So a histogram for property A, property B, property C, and so on....

I know how to do it for all properties, as seen in my below code:

df['duration'].plot(kind='hist', sharex=False, use_index=False, bins=100)
plt.show()

Any ideas on how I might go about this?

Answer 1

Nevermind, got it!

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.hist.html

df.groupby('property_name').hist(column='duration')

Answer 2

consider the following dataframe df

df = pd.DataFrame(dict(duration=np.random.rand(1000),
                       property_name=np.random.choice(list('abc'), 1000)))

Then you can do

df.groupby('property_name').hist(figsize=(10,2))
