I don't want to press Enter

I'm trying to visualize the evolution of two vectors.

My code look like as  :

    plstream pls(1);
    pls.sdev("tk");
    pls.scol0(0,255,255,255);
    pls.init();
    pls.scol0(1,0,0,0);
    pls.ssub(1,2);

    (...) definition of the vectors x, x2, y, y2

    for(int j =0;j<100;j++){

    (...) modification of y and y2

      pls.adv(1);
      pls.col0(1);
      pls.env( 0., 1., 0., 1., 0, 0 );
      pllab("(x)", "(y)", "y 1");
      pls.line( 6, x, y );

      pls.adv(2);
      pls.col0(1);
      pls.env( 0., 1., 0., 10., 0, 0 );
      pllab("(x)", "(y)", "y 2");
      pls.line( 6, x2, y2 );

      usleep(SLEEP_GRAPHE);
    }

I've two problems :

- I have to press ENTER to go to the next graph. What can I do to go automatically to the next graph ?
- I don't understand why the graph with x and y is in the bottom of the window and the graph with x2 and y2 in the top of the window. I was expecting the inverse.

Hello Berti:

Enter issue:
pls->spause(true);

Can't help you with the second one :-(
