Saving the plot: saveas does not seem to work
显示 更早的评论
I have the following code and I try to save the plot with "saveas" but it does not seem to work. Please advise.
x0=10;
y0=10;
width=375;
height=210;
set(gcf,'units','points','position',[x0,y0,width,height])
set(gca,'box','on')
% Remove tick marks from the plot
set(gca, 'TickLength', [0 0]);
plot(****, ****)
hold on
plot(****, ****)
hold on
plot(****, ****)
hold on
plot(****, ****)
% Place legend under the plot, centered
legend('****','****','****','****','Location', 'southoutside','Orientation','horizontal')
thandle = title({'****'});
yhandle=ylabel('****');
saveas(gca,'C:/****.png');

What error do you get?
Are you certain that you have write permission to the top level of the C: hard drive, as would be needed to write to C:/****.png ?

saveas(gca,'C:\filename.png');
tries to write into the top level directory of the C: drive. MS Windows does not permit users to write into that directory (not unless an administrator goes in and modifies the permissions for that directory.)
If you want to save into the "current" directory, leave out the 'C:\' , giving the file name as just 'filename.png' . If you want to save into the "current" directory of the C: drive, then leave out the \, giving the file name as just 'C:filename.png' (Note: MS Windows keeps a different "current" directory for each drive.)

If you do not need to know what the current directory is for a particular drive, then just give either of the commands
cd
or
pwd
If you need to know the current directory on a particular drive then
!cd C:
or
system('cd C:')
