title: Specifying colors for multiple lines on plot
body: <p><a href="https://stackoverflow.com/questions/41494942/pandas-dataframe-groupby-plot">Pandas dataframe groupby plot</a></p>
  <p>I have a similar dataframe to the one in the above question, but it has around 8 ticker symbols. I've defined a list of colours called 'colors' that correspond with the tickers, but when I do:</p>
  <pre><code>df.groupby('ticker')['adj_close'].plot(color=colors)
  </code></pre>
  <p>all the lines on the plot for each of the tickers are the same colour (i.e. the first colour in the list 'colors').</p>
  <p>I was wondering how I can specify the line for each ticker to be in its corresponding colour from the list 'colors'?</p>
  <p>Thanks in advance!</p>
