Removing Previously Drawn Graph Lines Without Reallocated (Programmatic Allocation)

[JudeMurphy]

Hey guys! I have to first say, this is a GREAT and easy-to-use custom class. A job well done!

One issue I had with it though. When programmatically defining a JYGraphView, and throwing it into a ViewDidLoad, I didn't want to reallocate my instance every time to remove the previously drawn lines with the updated Graph Data. So I created this method inside of JYGraphView. I was going to make a pull request, but I found out this was a private repo. So, here's the code. Figured anyone else that ran into the same problem could use it too:

// Used to clear previously drawn sublayers, or lines, and replots graph
// Be sure to update your JYGraphView's graphData and graphDataLabels before calling this

• (void)redrawGraphAfterUpdatingGraphData
  {
  [[self layer] setSublayers: nil];
  [self plotGraphData];
  }

Feel free to add this to your repo for JYGraphView!
