Major issue with Graphing

[nielswh]

Hi There,

I ran into an issue with the line plot and brought my app to its knees performance wise. I finally determined where the issue was. Its on line 73 of LineGraphView.m You make a call to
UIGraphicsPushContext(ctx); but then never call UIGraphicsPopContext();
I'm not 100% sure if you need either though.

Thanks,
Niels

I just added UIGraphicsPopContext(); at the end and then it worked great. Need the pop after the push :)
