title: Ploting 95% confidence interval line plot with shaded area in python
body: <p>I want to plot a 95% confidence interval of a data frame using python. The graph will be a line plot where the x-axis will indicate the column name/number, and the y-axis will indicate the column values. I search a lot but could find the solution that I was looking for. Here is an example of my data frame.</p>
  <pre><code>    Ph1        Ph2        Ph3        ph4       Ph5         Ph6
   -0.152511  -0.039428   0.131173  -0.002039  0.008101 -0.002039
   -0.068273   0.152013  -0.315244   0.005247  0.014775 -0.045268
    0.425363  -0.043105   0.071670  -0.045124 -0.036135 -0.037250
   -0.019332   0.139712  -0.026001  -0.021844 -0.040854 -0.050648

  </code></pre>
  <p>Also attached an example of my graph, in this plot I shown the how desired graph's x-axis and y-axis will be.<br />
