x1=-5:2.5:5;
x2=9:0.2:9.8;
y1=[8.5,5.2,0,6.6,7.7];
y2=[11.5,7.2,0,6.3,12.6];
hl1 = line(x1,y1,'Marker','*','Color','r');
ax1 = gca;set(ax1,'XColor','r','YColor','r')
ax1.XAxis.TickValues=[-5:2.5:5];
ax2 = axes('Position',get(ax1,'Position'),...           
    'XAxisLocation','top',...         
   'YAxisLocation','right',...        
   'Color','none',...         
   'XColor','k','YColor','k','ytick',[]);
ax2.YAxis.Limits=ax1.YAxis.Limits;
ax2.XAxis.Limits=[9 9.8];
ax2.XAxis.TickValues=[9:0.2:9.8];
hl2 = line(x2,y2,'Marker','o','Color','k','Parent',ax2);
