`imagesc` in MATLAB: paper size and `colorbar` -


i using imagesc in matlab show nxm matrix image, warmer color higher value. using following command:

f = imagesc(points, [0 1]);

the matrix points displayed. nevertheless, legend showing coupling between colors , values missing. have found out command:

colorbar

can used display requested legend. however, when printing figure on pdf using following lines of code:

set(gcf, 'paperunits', 'centimeters') set(gcf,'papersize',[12 8]) % set paper size figure size print('-dpdf',figurepath)

i encounter 2 problems:

  • the paper size not set properly
  • the color bar not showing on pdf

how can fix these problems?

thanks in advance,

eleanore.

i've found solution in state of art, uses export_fig script (https://sites.google.com/site/oliverwoodford/software/export_fig).

the following code needed:

set(gcf, 'color', 'w');                     % change background color set(gcf, 'position', [100 100 700 500])     % change figure dimensions export_fig([figurepath '.pdf'])             % export figure
