RE: Subplot size

[Henk Borsje]

I implemented your script more or less as you gave it, thank you.  Only minor 
difference is that I don't use a call to 'get' to find the plot position, only 
a call to 'set'. But when I resize the figure during or after execution of the 
script some of the subplots start dropping out.  The same thing happens when I 
change my default figure size before running the script. I've filed that as a 
bug.

Here is the sample code I use:

m = 8;
rnge = 0.5:9.5;
figure (1)
pos = [ 0.07, 0, 0.92, 0.5/m];

for k = 1:4
        d = rand(10,m);
        %clf;
        for i = 1:m
                pos(2) = 0.95 - i * 0.91/m;
                h = subplot(m,1,i);
                plot(rnge,d(:,i))
                set (h,'position',pos);
                if i == m
                        axis("label")
                else
                        axis("labely")
                endif
                grid,ylabel(sprintf('Series %d',i));
                if i == 1
                        title('My title')
                endif
        endfor
        pause(2)
endfor

By trial and error I managed to get to this (works on Octave 5.2.0 on Linux 
with fltk):

m = 8;
d = rand(100,m);
rnge = 1:100;
figure (1), clf
for i = 1:m
 ah = subplot(m,1,i);
 plot(rnge,d(:,i))
 if i == 1 title('My title') endif
 grid,ylabel(sprintf('Series %d',i));
 if i == m axis("tic","label") else axis("ticy","labely") endif  pos = 
get(ah,'position') .* [1 1 1.2 2.5] + [-0.075 -0.05 0 0];  set(ah, 'position', 
pos); endfor
