Problem with snapshot Pie chart iOS


#1
I used a sample Pie chart tutorial to make a snapshot but only legend displayed.

Included 2 files SChartGLVIew+Screenshot.h and ShinobiChart+Screenshot.h

UIImage *img = [_chart snapshot];

UIImageVIew *imageVIew = [[UIImageView alloc] initWithImage:img];

[self.view addSubView:imageView];

Any suggestion? Thanks a lot
