Multiple bars for each x axis value using matplotlib

Question

I am trying to have 2 bars for each time in the bar chart. X axis has to be time and y axis has to be count. For each time I am trying to plot 2 bars for each id.

  Id    Time Count
  585   10  9
  585   11  34
  585   12  96
  193   10  147
  193   11  85
  193   12  1

Tried with the below code but could not get the desired results. Any help would be really helpful.

Thanks in advance !!

  y = df1['Id']
  z = df1['Count']

  ax = plt.subplot(111)
  ax.bar(y, z,width=0.2,color='b',align='center')
  ax.bar(y, z,width=0.2,color='g',align='center')
  ax.xaxis_date()

  plt.show()

set_index + unstack

df.set_index(['Time', 'Id']).Count.unstack().plot.bar()

This time with Count as the ylabel

ax = df.set_index(['Time', 'Id']).Count.unstack().plot.bar()
ax.set_ylabel('Count')
