Hello everybody, 

I did solve the Problem with showing only 10 line
numbers, by using IF. 

printer=1

for k=1:A_size(1,1) //Beschriftung

IF K>A_SIZE(1,1)*(PRINTER/10) THEN 
 printer = printer + 1

xstring(x(k),y3(1),string(k)) 
 // xstring(x,y,str,[angle,[box]])
 end

set(handles.Anzeige, 'string', 'Diagrammbeschriftung ' + string(k) + '
von ' + string(A_size(1,1)))
end

The line numbering is connected to the
y-axis. How can I move the lattering aboth the plot (or at least the
bottom, next to the x-axis)? (attached plot:
subplot_with_line_number_2_tenth.gif)

About Jens help: 

I attached
three plots: the stacks Picture are with the Code of Jens. Stacking is
really nice, but I do not need every line number. With 921 data Points,
it is already unreadable again. But thanks for your ideas, the Code is
great for learningn anyway. 

Cheers

You can avoid overlapping of measurement numbers by sawtooth stacking
them. See example code below.

Why not using drawaxis() as already suggested? drawaxis() is made for
this kind of situation.

By the way, IMO, a drawing of what exactly is required would be clearer
