altering a 2d plot for a time series

This is a rather basic question but here we go. I'm plotting a time series of data, and was wondering if instead of having dates on the xaxis is it possible for the xaxis to be an arrow (does that make sense?). So basically shows that as the xaxis continues to the right, time also increases.

You can certainly add an arrow using text()
plot(randn(100,1));
set(gca,'xtick',[]);
text(46,-3.5,'\rightarrow','fontsize',20);
Obviously, you can adjust the position and size of arrow as you wish.

I think you should use the Xlim and Ylim values of the current axis to place your arror
x = randn(100,1);
plot(x);
ax = gca;
set(gca,'xtick',[]);
ylims = get(ax,'Ylim');
xlims = get(ax,'Xlim');
text(xlims(2),ylims(1),'\rightarrow','fontsize',20);
