I am trying to remove the border around a core plot graph on the iPhone - but seem to be struggling on what should be simple in my mind.
Pointers please!
You should be able to nil out the borderLineStyle on the graph's plotArea to remove the border:
graph.plotAreaFrame.borderLineStyle = nil; // don't draw a border
You could also create your own theme, using the ones in the framework as examples, and simply not set the borderLineStyle in that.
