title: Pandas.plot Multiple plot same figure
body: <p>I have multiple CSV files that I am trying to plot in same the figure to have a comparison between them. I already read some information about pandas problem not keeping memory plot and creating the new one every time. People were talking about using an ax var, but I do not understand it...</p>
  <p>For now I have:</p>
  <pre><code>def scatter_plot(csvfile,param,exp):
      for i in range (1,10):
          df = pd.read_csv('{}{}.csv'.format(csvfile,i))
          ax = df.plot(kind='scatter',x=param,y ='Adjusted')
          df.plot.line(x=param,y='Adjusted',ax=ax,style='b')
      plt.show()
      plt.savefig('plot/{}/{}'.format(exp,param),dpi=100)
  </code></pre>
  <p>But it's showing me ten plot and only save the last one.
  Any idea?</p>
