matlab导出图片背景_保存具有不同背景颜色的MATLAB图形

I want to print a MATLAB figure with a dark background and white labels. If I use the print or saveas command I lose somehow the colors. The plot symbols are dark again and the background is white.

points = rand(100,3);

plot3(points(:,1),points(:,2),points(:,3),'*w')

grid on

set(gca,'Color',[0.5 0.5 0.5])

saveas(gcf,'test1','pdf')

saveas(gcf,'test2','png')

print(gcf,'test3.pdf','-dpdf')

All three test files end up being wrong. If I choose "Save As" in the figure menu I am able to save the figure correctly.

Any ideas how to resolve the issue?

To keep the background as in your figure, use the command set.

set(gcf, 'InvertHardCopy', 'off');
