MATLAB: Cannot save image with white background

background colorisocapsisosurface

I can't manage to save my image with white background. I generated the image by using isocaps and isosurface. I used also contours and patch.
I tried the following: set(gcf,'invertHardcopy','off') print -djpeg thefilename.jpg print -dbmp thefilename.jpg
I also tried: [X,map]=getframe; >> imwrite(X,map,'thefilename.jpg')
Then I tried: saveas(gcf,'thefilename.png')
In all the cases I always get black background. Could somebody give a hint? Thanks in advance Isabella please find enclosed the image. I am using Matlab R2011b 32 bit 7.13.564
