    set(htab,'Units',units);

    titlepos = [0,0,0,titleheight];
    if sign(4)
      panelpos = [0,titleheight+1,tabpos(3),tabpos(4)-titleheight]+margins;
      titlepos(2) = panelpos(2)-titlepos(4);
    else
      panelpos = [0,0,tabpos(3),tabpos(4)-titleheight]+margins;
      titlepos(2) = panelpos(2)+panelpos(4);
    end
