how to draw a histogram in python matplotlib? -

my data name called ranges_freq below

    buckets     userid    0   10           730    1   50           435    2   100          150    3   500          314    4   1000         97    5   1001         244   

i able draw bar chart using below code unable draw histogram same data.

>y = ranges_freq['userid']  xlabels = ranges_freq['buckets']  bar_width = 0.50  x = np.arange(len(y))  fig, ax = plt.subplots()  ax.bar(x, y, width=bar_width)  ax.set_xticks(x + (bar_width/2.0))  ax.set_xticklabels(xlabels)  ax.set_title('user frequency range')  ax.set_xlabel('buckets')  ax.set_ylabel('no.of.users')  plt.show()

so remove spaces in bar chart, thing need do, set

bar_width = 1.0
