Loop through only the distinct values in a file
Datafile has the following data seperated by :
FIELD1:FIELD2:FIELD3
D1:/opt/9.1.9:Y
D2:/opt/10.1.10:Y
D3:/opt/9.1.9:Y
D4:/opt/8.1.8:Y
D5:/opt/8.1.8:Y
D6:/opt/9.1.9:Y
D7:/opt/9.1.9:Y
D8:/opt/10.1.10:Y
D9:/opt/9.1.9:Y
D10:/opt/10.1.10:Y
I want to do some operations only on the distinct values of FIELD2 in a loop.

plot3d
PLOT3D(3plplot) PLplot API PLOT3D(3plplot)
NAME
plot3d - Plot 3-d surface plot
SYNOPSIS
plot3d(x, y, z, nx, ny, opt, side)
DESCRIPTION
Plots a three dimensional surface plot within the environment set up by plw3d(3plplot). The surface is defined by the two-dimensional
array z[nx][ny], the point z[i][j] being the value of the function at (x[i], y[j]). Note that the points in arrays x and y do not need to
be equally spaced, but must be stored in ascending order. The parameter opt controls the way in which the surface is displayed. For fur-
ther details see the PLplot documentation. The only difference between plmesh(3plplot) and plot3d(3plplot) is that plmesh(3plplot) draws
the bottom side of the surface, while plot3d(3plplot) only draws the surface as viewed from the top.
Redacted form: plot3d(x, y, z, opt, side)
This function is used in examples 11,21.
ARGUMENTS
x (PLFLT *, input)
Pointer to set of x coordinate values at which the function is evaluated.
y (PLFLT *, input)
Pointer to set of y coordinate values at which the function is evaluated.
z (PLFLT **, input)
Pointer to a vectored two-dimensional array with set of function values.
nx (PLINT, input)
Number of x values at which function is evaluated.
ny (PLINT, input)
Number of y values at which function is evaluated.
opt (PLINT, input)
Determines the way in which the surface is represented: opt=DRAW_LINEX: Lines are drawn showing z as a function of x for each value
of y[j]. opt=DRAW_LINEY: Lines are drawn showing z as a function of y for each value of x[i]. opt=DRAW_LINEXY: Network of lines is
drawn connecting points at which function is defined.
side (PLBOOL, input)
Flag to indicate whether or not ``sides'' should be draw on the figure. If side is true sides are drawn, otherwise no sides are
drawn.
