Plotting using multiple x-axes and y-axes.

Hi everyone, i am plotting two curves on a same figure, since the x-axis scale is different for both of them, so i am using multiple x-axes and y-axes option. I am having a problem with the axes command which gives me the following error message. *Error using axes Value must be a 4 element vector.
Only the first graph is plotting. Thank you.
figure(9);
line(x1,y1,'Color','r')
ax1 = gca; % current axes
set(ax1,'XColor','r');
set(ax1,'YColor','r')
ax1_pos=set(ax1,'Position');
ax2 = axes('Position',ax1_pos,...
'XAxisLocation','top',...
'YAxisLocation','right',...
'Color','none');
line(x2,y2,'Parent',ax2,'Color','k');

...
ax1_pos=set(ax1,'Position');
ax2 = axes('Position',ax1_pos,...
ax1_pos will be empty after the above; you (probably inadvertendtly) typed set instead of get.
Try
ax1_pos=get(ax1,'Position');
instead.
