Is there a way to plot the function and then the axes. Normally this is not necessary, but when plotting a dense white noise one cannot read the ticks ?

You may use the options zorder and alpha. Graphic objects with high zorder are rendered on the top layers, so they are more visible. Likewise, objects with alpha near 0 are nearly transparent. Compare the three graphics yielded by the following code:

p1 = plot(sin(1/x), (x,-0.1,0.1), color="red")
p2 = plot(sin(1/x), (x,-0.1,0.1), color="red", zorder=0)
p3 = plot(sin(1/x), (x,-0.1,0.1), color="red", alpha=0.6)
graphics_array([p1,p2,p3])
