How can I export figure as png?

I have the script which creates 3D figure. The only way to save it is

hgsave(graph, [input, output, '\', string{i + 8}, '.png'],'-v7.3');

I tried different ways to save it as png and all failed. It stores only axis.

print(graph,'-dpng',[input,output,'\',string{i +8},'.png']);
saveas(graph, [input, output, '\', string{i + 8}], 'png');
hgexport(graph, [input, output, '\', string{i + 8}, '.png'], hgexport('factorystyle'), 'Format', 'png');

Best option is to use the export_fig function from the file exchange. It actually works out of the box and intuitively (not like the annoying builtin saveas function)

I have some problem in my installed Matlab. can you send me any proper person link to guide me for this issue. When i am going to save my figures, its show some errors, even i have installed Mapping toolbox.

Warning: Probably because you do not have Mapping Toolbox, getar was performed by an approximative method.

Hi,

I create a figure and save it with the follwoing command:

saveas(gcf,'picture.png')

Perhaps

saveas(gcf, [input, output, '\', string{i + 8}], 'png');

works.

All I tried didn't work. Even if I select Save as from figure menu it still save only the axis.

Did you try another renderer? I can't really explain a lot about it, but I think I once had a similar problem (though everything was black in my case) and choosing another renderer has fixed the case.

In case neither this nor the other suggestions work: I feel a bit embarrassed to mention it here, but once I was desperate enough to simply make a screenshot and save this. In case none of the solutions here works, this will for sure.
