Hi there,
I printed a figure with a black background and axes handle, but can't seem to reduce the margin when saving it using "print" comment.
Please see below example of the code - dimensions is correct, but when i defined axes position as [0 0 1 1] it still leaves some margins on the background (see attached figure).
Any suggestion?
figure;
def.dimensions = [6 6]; % Width & Height in cm
set(gcf, 'PaperPositionMode', 'manual');
set(gcf, 'PaperUnits', 'centimeters','PaperOrientation','Portrait');
xSize = def.dimensions(1); ySize = def.dimensions(2); set(gcf,'paperposition',[0 0 xSize ySize])
ax = axes('Position',[0 0 1 1],'Box','off');
colID = randsample(nCols,1);
plot(x,y,'LineStyle','-','LineWidth', 0.1,'Color', BrightCol.Code(colID));
axis equal;
ax.XAxis.Color = 'none'; ax.YAxis.Color = 'none'; set(ax,'XColor', 'none','YColor','none'); set(ax,'Visible','off');
set(gcf,'color',[0.1 0.1 0.1])
set(gcf, 'InvertHardCopy', 'off');
outdir = [ outputDir,char(nameGroups(i)),'\'];
filename = [outdir,[fileID,'.jpeg']];
print(gcf, filename, '-djpeg', '-r1200');

It would help if you provided code that can be executed. As is, your code crashes because it accesses unitialized variables.

If you are using R2020a or later you can use the exportgraphics command:
% in R2020a or later - create file in current directory:
exportgraphics(gcf, 'output.jpg', 'Resolution', 1200);
exportgraphics will eliminate most of the "margins" typically included when using the print command
