  <p>This is my dataframe.</p>
  <p>The question is not actually a homework question ,but a real problem I am facing.</p>
  <p>There are methods in documentaion using which I can adjust the parameter in multiple bar, bargraph. But they are lengthy.</p>
  <p>I have made the bargraph using &quot; df1.plot.bar() &quot; this command. df1 is the name of the dataframe.
  and I have got a bar graph like this.</p>

  <p>After using this command I was not able to change its width and color . all the methods for changing these parameter has been in matplotlib,  but I have made the graph using pandas library. Now I am facing problems in changing parameters in graph and legends and all.  Now How can I apply parameters of matplotlib in this bargraph?</p>
  <p>please don't use backend() approach. I am a novice in data visualisation.</p>
