[Jens Simon Strom]

Hello Frieder,
Your plots look better now. You can avoid overlapping of measurement 
numbers by  sawtooth stacking them. See example code below.

xdel();
//Generating dummy measurements x,y
dx=0.5:50;
x=cumsum(dx);
y=sind(x);
nM=length(x);//number of measurements
plot(x,y,'r')
plot(x,y,'b+')
//Plotting the measurement numbers in stacks to avoid overlapping
nstack=6;//number of stacked measurement numbers
hstack=0.2;//height of measurement number stack (relative to window height)
ybase=-0.9;  //base ordinate for measurement numbers
yspan=max(y)-min(y);
for  m=1:nM//measurement number
   xstring(x(m),ybase+(modulo(m,nstack)-1)*hstack*yspan/nstack,string(m))
end

Kind regards
Jens
