How can I use matlab to plot a graph where the x,y axes do not intersect? Similar to the image below, note that the bottom left corner does not cross.The x- and y-axes are shown with specified ranges

not elegant, but possible if i'm not mistaken:
fig=figure;
% amount of shift of x and y axis in normalized coordinates
dx=0.05;
dy=0.05;
plotAx=axes('Position',[0.1 0.1 0.85 0.85],'Color','none');
% create shifted y axis
yax=axes('Position',plotAx.Position-[dx 0 -dx 0],'Color','none','XColor','none');
yax.XGrid='off';
% create shifted x axis
xax=axes('Position',plotAx.Position-[0 dy 0 -dy],'Color','none','YColor','none');
xax.YGrid='off';
axes(plotAx); % set curr axis
% plot sample data
x=-2:0.1:2;
y=(x-1).^2+1;
plot(plotAx,x,y)
grid off;
linkaxes([plotAx,yax,xax]);
yticklabels([]);
xticklabels([]);
% remove rulers
plotAx.XColor='none';
plotAx.YColor='none';

I'm not so sure disconnected axes is a very popular idea. What's the benefit of doing this, by the way? Curious.

Create your figure first, then create the axes. This will allow you to specify what they are before the data gets populated, and should allow you to fix their positions.
I have not looked at the documentation in enough detail to confirm it will do exactly what you want, but it should be in the axes command.

cui is correct here. There are no axes properties that can achive this. There are, however, undocumented ruler properties that can achieve at least some of it.
