Dear Gromacs users

After I calculated the secondary structure of residues from 1 to 59 using
do_dssp during 20 ns MD simulation, I used xpm2ps to show the picture with
ps.m2p.

y-axis is true but x- axis is very long.

My ps.m2p file is as follows:

; Command line options of xpm2ps override the parameters in this file
black&white              = no           ; Obsolete
titlefont                = Times-Roman  ; A PostScript Font
titlefontsize            = 20           ; Font size (pt)
legend                   = yes          ; Show the legend
legendfont               = Times-Roman  ; A PostScript Font
legendlabel              =              ; Used when there is none in the
.xpm
legend2label             =              ; Used when merging two xpm's
legendfontsize           = 14           ; Font size (pt)
xbox                     = 2.0          ; x-size of a matrix element
ybox                     = 2.0          ; y-size of a matrix element
matrixspacing            = 20.0         ; Space between 2 matrices
xoffset                  = 0.0          ; Between matrix and bounding box
yoffset                  = 0.0          ; Between matrix and bounding box
x-major                  = 5           ; Major ticks on x axis every ..
frames
x-minor                  = 1            ; Id. Minor ticks
x-firstmajor             = 0            ; First frame for major tick
x-majorat0               = no           ; Major tick at first frame
x-majorticklen           = 8.0          ; x-majorticklength
x-minorticklen           = 4.0          ; x-minorticklength
x-label                  =              ; Used when there is none in the
.xpm
x-fontsize               = 16           ; Font size (pt)
x-font                   = Times-Roman  ; A PostScript Font
x-tickfontsize           = 10           ; Font size (pt)
x-tickfont               = Helvetica    ; A PostScript Font
y-major                  = 10
y-minor                  = 5
y-firstmajor             = 0
y-majorat0               = no
y-majorticklen           = 8.0
y-minorticklen           = 4.0
y-label                  =
y-fontsize               = 16
y-font                   = Times-Roman
y-tickfontsize           = 10
y-tickfont               = Helvetica

How to solve this problem?

Any help will highly appreciated.
