Not quite sure about that. Maybe if you could describe in a few words how zooming the graph works I could take a shot at it. My guess is that the gradient is redrawn for the visible graph if the graph changes (f.e when zooming the graph). If this is the case a possible fix could be to draw the gradient only once, or when necessary. However I did not look at the code since I am on a mobile phone right now. Can you confirm that the graph is redrawn when zooming or is it a simple transform ?
