title: Plotting Multiple Items as line graph in Matplotlib
body: <p>I have a pandas dataframe like so:</p>
  
  <pre><code>Date     Allotment  NDII_Mean  NDVI_Mean  RGR_Mean  SATVI_Mean

  <p>I want to plot based on allotment, so I will need to use groupby.  So for each Allotment I want the Date on the X-Axis, and all four of the columns with mean in the name shown as lines on the graph and their values on the Y-Axis.  I will then save them as pdf's, although it is not necessary that I do if someone knows another way.  I can plot ONE value using this code (I'll lot NDII_Mean in this example) but I want to plot all four of the columns not just one.  The code I am using is:</p>
  
  <pre><code>import pandas as pd
  import matplotlib.pyplot as plt
  from matplotlib.backends.backend_pdf import PdfPages
  
  df=pd.read_csv('C:/Users/Stefano/Documents/Hurst_plots.csv')
  
  with PdfPages('C:/Users/Stefano/Documents/Hurst_plots.pdf') as pdf:
     for i, group in df.groupby('Allotment'):
  
          plt.ylabel('Values')
          plt.figure()
  
          Hurst_plots=group.plot(x='Date', y='NDII_Mean',title=str(i)).get_figure()
          pdf.savefig(Hurst_plots) 
  </code></pre>
  
  <p>This is what one of the plots looks like (different than data shown because I shortened my example table):</p>

  <p>edit:</p>
  
  <p>This works by adding editing this line</p>
  
  <pre><code>Hurst_plots=group.plot(x='Date', y=['NDII_Mean', 'RGR_Mean', 'SATVI_Mean', 'SWIR32_Mean'],title=str(i)).get_figure()
  </code></pre>

  <p>but does anyone know how to take the legend outside of the graph completely?</p>
