title: FutureWarning: Using a non-tuple sequence for multidimensional indexing is deprecated use `arr[tuple(seq)]` instead of `arr[seq]`
body: <p>I would like not to use the non-tuple sequence for multidimensional indexing so that the script will support future release of Python when this changes.</p>
  
  <p>Below is the code that i am using for plotting the graph:</p>
  
  <pre><code>data = np.genfromtxt(Example.csv,delimiter=',', dtype=None, names=True, 
      converters={0: str2date})
  
  p1, = host.plot(data["column_1"], data["column_2"], "b-", label="column_2")
  p2, = par1.plot(data["column_1"], data['column_3'], "r-", label="column_3")
  p3, = par2.plot(data["column_1"], data["column_4"], "g-", label="column_4")
  
  host.set_xlim([data["column_1"][0], data["column_1"][-1]])
  host.set_ylim(data["column_2"].min(), data["column_2"].max())
  par1.set_ylim(data["column_3"].min(), data["column_3"].max())
  par2.set_ylim(data["column_4"].min(), data["column_4"].max())
  </code></pre>
