title: Pandas Dataframe Line Plot: Show Random Markers
body: <p>I often have dataframes with many obervations and want to have a quick glance at the data using a line plot.</p>
  
  <p>The problem is that the colors of the colormap are either repeated over X observations or hard to distinguish e.g. in case of sequential colormaps.</p>
  
  <p>So my idea was to add random markers to the line plot which is where I got stuck.</p>
  
  <p>Here's an example with one markerstyle:</p>
  
  <pre><code># -*- coding: utf-8 -*-
  import pandas as pd
  import numpy as np
  import matplotlib.pyplot as plt
  
  # dataframe with random data
  df = pd.DataFrame(np.random.rand(10, 8))
  
  # plot
  df.plot(kind='line', marker='d')
  plt.show()
  </code></pre>
  
  <p>which delivers:</p>

  <p>Is it also possible to draw a (random) marker for each line?</p>
  
  <p>Thanks in advance!</p>
