title: plt.ioff() isn't working. How do I plot several different graphs
body: <pre><code>plt.ioff()
  for i in range(0,len(variableList)):
      graph = lag1['VDC'].rolling(window=24).corr(other=lag1[variableList[i]])
      plt.title(variableList[i])
      plt.plot(graph)
      plt.axhline(y=0)
      plt.savefig(variableList[i])
  </code></pre>
  
  <p>I want to plot several different independent graphs. The default is in interactive mode where each new graph is plotted on the previous one. I read the document and found that I need to use plt.ioff(). However adding this line doesn't change anything. </p>
