matplotlib - Plot histograms per column from pandas dataframe -



matplotlib - Plot histograms per column from pandas dataframe -

my dataframe looks like:

buy_he sell_he buy_tr sell_tr buy_am sell_am 2009-08-01 00:00:00 28 0 0 0 0 20 2009-08-01 00:15:00 28 0 0 0 0 20 2009-08-01 00:30:00 28 0 0 0 0 20 2009-08-01 00:45:00 28 0 0 0 0 20 2009-08-01 01:00:00 nan nan 15 0 0 19 2009-08-01 01:15:00 nan nan 15 0 0 19 2009-08-01 01:30:00 nan nan 15 0 0 19 2009-08-01 01:45:00 nan nan 15 0 0 19 2009-08-01 02:00:00 nan nan 0 0 0 57

and on.

i wanted plot histograms every data-column. tried df.hist(). nothing. maybe there problem nan? (the nan`s @ beginning, or @ end of column, or both. never in middle of column)

what do?

matplotlib pandas
