I want to get electric field intensity profile along the waveguide

(for example each point in x direction )
How can I do?
in meep reference, (get-field-point c pt) function is used for
single point.
I need field intensity-position graphs.
Maybe, I should write script to get intensity at every point along
the axis.
But I have not full knowledge of programming.
Could you show me how to solve this problem?
Just use the in-volume command to restrict an HDF5 output to a line
along the waveguide axis. e.g.
(in-volume (volume (center 0 0 0) (size 10 0 0)) output-dpwr)
outputs epsilon*|E|^2 along a line of length 10 in the x direction,
centered at (0,0,0). You can even wrap this in a (to-appended
"line.h5" .......) command to output the intensity along the line as a
function of time to a 2d HDF5 dataset (so you could easily plot
intensity vs. time and space in a 2d color image, for example).
