title: extracting points from a graph in python
body: <p>I was looking for a way to extract points from 4 graphs i have plotted in Python in order to run the Ramer Douglas peucker algorithm on the points. Ideally the data would be presented in a series of x and y co-ordinates as the current data set is presented differently. Each graph is made up of around 2000 points but they are not formatted as X and Y co-ordinates in the data set. I have attached the code used to plot the graphs as well as the data set if anyone has any suggestions.</p>
  
  
  
  <p>Cheers!!</p>
