Plot displacement history in Gnuplot

A history plot of the vertical displacement of the post_point in the file "post_point_dof_10_disy.his" shows what is happening when the cohesion and friction angle are lowered in time between 1.0 and 2.0. Here we use Gnuplot as plotting program, but since the file "post_point_dof_10_disy.his" is a simple ASCII text file you can use any program of your preference for plotting. With Gnuplot do the following for getting a postscript result of the displacement history:

gnuplot

p "post_point_dof_10_disy.his" with lines

set term postscript

set output "post_point_dof_10_disy.ps"

replot

Clearly finally the slope becomes unstable.
