Question: Plotting graphs

How do i plot a graph  of  (H .vs. X/(2.Pi.sqrt(2))) for different values of time =t

H is the film thickness

When I plot my values, I get a normal graph of H .vs. X, but I need to see the above mentioned graph.

Please suggest solutions.

The command which I wrote for my graph generation, looks like this:::::::::

> IBC := {h(x, 0) = 1+0.1e-2*sin(x/sqrt(2)), (D[1](h))(0, t) = 0, (D[1](h))(2*Pi*sqrt(2), t) = 0, (D[1](D[1](D[1](h))))(0, t) = 0, (D[1](D[1](D[1](h))))(2*Pi*sqrt(2), t) = 0};
> smod := pdsolve(PDE, IBC, numeric, method = CrankNicholson);
> p1 := smod:-plot(t = 0, color = red);p2 := smod2:-plot(t = 1, color = maroon);p3 := smod2:-plot(t = 2, color = green);plots[display]({p1, p2, p3});

This resulting graph plots values from 0-8 on the X axis but I want it to show 0-1 which is X/(2.Pi.sqrt(2))
