tot_title and plot data file in blocks

[Mr. Stone]

Hi Dmitri,

Sure I will replot it... in fact I write the them in m-script. like:
#---------------------
tot_title("Top title for 2 diagrams");
x=0:0.1:10;
title("Title #1");
subplot(2,1,1);
plot (x,sin(x)),
#
title("Title #2");
subplot(2,1,2);
plot(x, cos(x));
#-----------------------
It seems a old thread: 
http://www.octave.org/octave-lists/archive/bug-octave.1999/msg00104.html
But no solution found..

Of my second question:
But I have a data file with dozens of blocks seperated by a blank line, e.g. 
mydata.dat:
#-----------Data Block#1
1  1
2  2
3  3
#-------End of Block#1

#-----Data Block#2
4  4
5  5
6  6
7  7
#-------End of Block#2
...

If I do a=load "mydata.dat" in octave, I will get [a] only in 2 columns 
like:
1  1
2  2
3  3
4  4
5  5
6  6
7  7
plot(a(:,1), a(:,2)) will plot the the whole 2 columns, not by blocks. How 
is that possible to plot within blocks and seperated by each blank line?

regards.

Stein
