constrain yaxis limits

[kamaraju kusumanchi]

Is it possible to just set limits on the y-axis and autoscale the
x-axis? I want the y-axis to always range from [-1:1]. The x-axis
limits are chosen automatically from the data

nu=100; u=rand(nu,1); v=rand(nu,1); w=u+v; plot(w, '-+'); grid

I looked in the documentation about axis( limits) function. It says
the limits vector should be a 2, 4, 6 element vector specifying the
limits on x,y,z axis. However in my case, I do not know the limits on
x, but only on y. Any suggestions/comments?
