Setting axis limits of a plot

I have two sets of data, x and y which I am plotting together:

plot(x,y)

I'm having a problem setting the axis limits however. I am using the method shown in the online documentation:

axis([xmin,xmax,ymin,ymax])

Or in my case:

axis([1,1024,1,1024])

The problem is when I enter this it creates a new figure with the correct limits but with no data plotted.

[Paulo Silva]

axis(gca,[1,1024,1,1024])

or

ax=axes
plot(x,y)
axis(ax,[1,1024,1,1024])

Thankyou for this, however I've just realised that I was making a mistake and the reason it was blank is because the data wasn't within the limits specified.

On a side note is there any way to change the direction of an axis, for example the y axis has 0 at the top and 1024 at the bottom?

set(gca,'ydir','reverse')

or simply:
