You could try something like this,
magfactor = 4; %play with this.
sprows = 8 * magfactor - 1;
spcols = 5;
for i = 1 : nvar
sp_logical_row = 1 + floor((i - 1) ./ spcols);
sp_logical_col = i + mod(i - 1, spcols)
sp_group = (sp_logical_row - 1:sp_logical_row + magfactor - 1 - 1) * magfactor + sp_logical_col;
subplot(sprows, spcols, sp_group);
.... drawing commands here
end
If I have worked everything out correctly, then what this does is divides each row up into "magfactor" parts, and draws in the top (magfactor - 1) of them, leaving the bottom one empty to provide a buffer between rows.
