Solved:
ax2.XTickLabelMode = 'manual'; ax2.XLim = [0 40];
works fine for this example.

i tried this example, but have some problems to scale the xtick from the upper axis.
figure x1 = 0:0.1:40; y1 = 4.*cos(x1)./(x1+2); line(x1,y1,'Color','r') ax1 = gca; % current axes
ax1_pos = ax1.Position; % position of first axes ax2 = axes('Position',ax1_pos,... 'XAxisLocation','top',... 'YAxisLocation','right',... 'Color','none');
set(ax2,'XTickLabel',[0:5:40]) set(ax2,'xtick',get(ax1,'xtick'))
The set(ax2,'xtick',get(ax1,'xtick')) wont work ...
