Thank you very much guys,
though I still haven't solved the problem satisfactorily.
The code bellow is a slight modification of Ben's code:
---
map = jet();
colormap(map);
margin = 100;
freespace = 200;
width = 1024;
height = 256;
fwidth = width + 2*margin + freespace;
fheight = height + 2*margin;
fpos = [0 0 fwidth fheight];
apos = [margin/fwidth, margin/fheight, width/fwidth, height/fheight];
figure ("position", fpos)
clf
image (rand (height, width), "cdatamapping", "scaled")
colorbar();
set (gca, "position", apos);
---
There are two problems:
1) The size of figure is absolutely resistant to the changes of /freespace/
variable. The size of axes is changed instead (Win7, gnuplot for displaying
the figures).
2) Colorbar is taken as a part of axes, so it seems to me that without
knowing the width of generated colorbar I cannot set properly the width of
axes in order to display matrix as matrix of coloured pixels.
Cheers, Marek
