title: Plotting csv file data to line graph using matplotlib
body: <p>I have the following data in result.csv file, and I need to plot into a line graph.</p>
  
  <pre><code>ColA    ColB
  93      46
  94      56 
  95      66 
  97      76 
  100     86
  103     96
  110     106
  </code></pre>
  
  <p>What I have is </p>
  
  <pre><code>from numpy import genfromtxt
  import matplotlib.pyplot as plt
  per_data=genfromtxt('result.csv',delimiter=','
  plt.xlabel ('x stuff')
  plt.ylabel ('y stuff')
  plt.title('my test result')
  plt.show()
  </code></pre>
  
  <p>How do feed each column of data into the graph and see its trend? The size if each column will grow daily because of new data. </p>
