"16.1 Two-Dimensional Plotting" is unclear

[Sergei Steshenko]

Hello All,

I'm writing this after observing that my 'plot' commands have destructive
behavior, i.e. new plot is drawn in the same window, completely destroying
previous one.

So, I've decided to reread

http://www.gnu.org/software/octave/doc/interpreter/Two_002dDimensional-Plotting.html#Two_002dDimensional-Plotting
.

I didn't find an explanation telling how to make each new plot command to draw
the plot in a new window.

I also didn't find any useful info on handles - all I found is:

"
— Function File: axes (h)
 
Create an axes object and return a handle to it.
...

— Function File: line (x, y, z, opts)
 
Create line object from x and y and insert in current axes object. Return handle to line object.
...
".

So, if I didn't miss something, I'm told a handle is created, but I'm not told what
can/should be done with that handle.

Any clarifications ?

Thanks,
  Sergei.

P.S.

The last line on the page is:

— Function File: newplot ()

- no explanation after it.
