3 questions regarding function migration from 2.1.73 to 3.0.3

Look in the "Axis properties" section of the manual.  An example is
  subplot(1,2,2);
  colormap(jet(range(plim)));
  set(gca,"outerposition",[0.73,0.053,0.4,0.935]);

>2. How can I make multiline title in printed plot?  I used to do the way:
>title(strcat('{/Helvetica=12 {/bold Original and unwrapped output signal 
>for AZIMUTH}}\n',txtf)),
>but now "\n" does not work.

I think you should use "" rather than '' to have \n work.

>3. Can I add timestamp to prints without using:
>__gnuplot_set__ timestamp "{/Helvetica=8 Generated by StatGen 1.0RC8 for 
>Octave on %d.%m.%y %H:%M}" screen bottom 0,-20; ?

Look at the 'text' function.
