Hi

I am having problems printing matlab figures because the location of annotation gets changed. To illustrate this please run the small script at the end of this message. The problem I want to solve is - the eps output should resemble the figure being displayed on the screen. Unfortunately this is not the case.

Any help will be appreciated.

Thanks
Deepak

close all;
clear all;

figure_position = [0 0 800 600];

figure(1);
set(gcf,'Position',figure_position);
frame = zeros(516,500);
frame(:,100-5:100+5) = 10000 + zeros(516,11);
frame(:,200-5:200+5) = 10000 + zeros(516,11);


display_frame = frame;

axes
axis_position = [100 100 516 500];
set(gca,'Units','pixels','Position',axis_position);
im = imagesc(display_frame',[1000 16000]);colormap(flipud(gray));
axis off; axis tight;

pos = [axis_position(1)/figure_position(3) axis_position(2)/figure_position(4) axis_position(3)/figure_position(3) axis_position(4)/figure_position(4)];
x_lim = xlim;
y_lim = ylim;
text_offset = 5;
arrow_offset = -2;

index = 100;
text(x_lim(2)-60,index+text_offset,['Text 1']); annotation('arrow',pos(1)+pos(3)*([450 400]-x_lim(1))/(x_lim(2) - x_lim(1)),pos(2) + pos(4)*(-[index index]+y_lim(2)+arrow_offset)/(y_lim(2) - y_lim(1)));

index = 200;
text(x_lim(2)-60,index+text_offset,['Text 2']); annotation('arrow',pos(1)+pos(3)*([450 400]-x_lim(1))/(x_lim(2) - x_lim(1)),pos(2) + pos(4)*(-[index index]+y_lim(2)+arrow_offset)/(y_lim(2) - y_lim(1)));

print -f1 -r1200 -depsc 'test.eps';

I think I found a probable way to avoid this. By being able to pin the arrows to axes. However there are a lot of arrows in my real figure, and I would like to do it by a script rather than GUI for all the arrows. Does anyone know of a command to pin annotations?

Thanks
