title: Plotting date and currency and convert the date to a readable format
body: <p>I'm trying to write a python 3 code that can take the data that I found on a website and convert it into a graph that I want to analyze using Pandas. the data looks like this </p>
  
  <p>[1533103200000,7200],[1535781600000,7547],[1538373600000,7250],[1541052000000,7684],[1543647600000,8499],[1546326000000,8150],[1549004400000,8600],[1551423600000,9250],[1554098400000,11545],[1556690400000,10444],[1561766400000,8697]</p>
  
  <p>each piece of data in the brackets is a plot point. The X (left) coordinate is the date in unicode and the Y (right) coordinate is the price. </p>
  
  <p>I have tried basic plot charting, but it keeps telling me that I cant convert the string to float</p>
  
  <p>x, y = np.loadtxt('data.txt', delimiter=']''[', unpack=True)
      plt.plot(x,y, label='Loaded from file!')</p>
  
  <pre><code>plt.xlabel('x')
  plt.ylabel('y')
  plt.title('Interesting Graph\nCheck it out')
  plt.legend()
  plt.show()
  </code></pre>
  
  <p>How do I take that data and put it into a format that pandas can recognize? </p>
  
  <p>How can I make those pieces of data into what I want? (date, currency)?</p>
