Sorry about that us. I accidently posted the query twice. Thanks for your input.

Typo in updating block indices corrected...

for idx=1:length(blks)
h(idx)=subplot(20,1,idx); % probably find this too many, but...
i2 = i1+blks(idx); % end point this block
plot(x(i1:i2,2),x(i1:i2,3));

% here...
i1 = i2+1; % 1st next block one past end this one
end

drat I _hate_ it when that happens... :(

Yes, I had just posted the correction...sorry about that; fortunately it
was a pretty obvious one...
