Zoom out problem with two x-linked axes containing data in different ranges

Hi all

I have a zoom problem when plotting in two x-linked axes and would be very happy for any suggestions to solve the problem.

Here's an example:

x1 = 5:10;
y1 = 5:-1:0;
x2 = 0:10;
y2 = 0:10;

hl1 = line(x1,y1,'Color','r');
ax1 = gca;
set(ax1,'XColor','r','YColor','r')

ax2 = axes('Position',get(ax1,'Position'),...
           'XAxisLocation','top',...
           'YAxisLocation','right',...
           'Color','none',...
           'XColor','k','YColor','k');  

hl2 = line(x2,y2,'Color','k','Parent',ax2);

linkaxes([ax1 ax2],'x')

The problem in the resulting plot is that xlim goes from 5-10 and not 0-10 as it should. Even when I try to zoom out the zooming only goes as far as xlim([5 10]) thus leaving out some of the (x2,y2)-data in the plot.

When plotting (x1,y1) in ax2 and (x2,y2) in ax1 the problem no longer exists, however, I would like to find a different solution as this solution is not really an easy implementation in my actual application.

Any suggestions are appreciated.

Best, SP
