That means, octave's subplot (r,c,n) corresponds to ML's subplot (r,c,n, 'align', replace') which causes axis labels to overlap. If the subplots don't have titles of their own, this simple code seems to work: set (gcf,'NextPlot','add'); axes; h = title ('MyTitle'); set (gca,'Visible','off'); set (h,'Visible','on'); Paw 10 years ago Post by Arseny set (gcf,'NextPlot','add'); axes; h = title ('MyTitle'); set (gca,'Visible','off'); set (h,'Visible','on'); Worked like a charm. pos specifies the "position" property Place the colorbar at the bottom of the plot. treated as the axes handle in which to add the colorbar.

Each axes could been panned, scrolled, zoomed, or data cursored individiually. The optional return value h is a graphics handle to the created annotation object. On the other hand, a single movable graphics cursor covering multiple images would become easier than in the other approaches mentioned above, >Answer by MathWorks Support Team on 26 Apr 2010.
