Dear,
Could you help me?

With the code below generate a 2D map in PNG :

aux2=3129.0/1440
set term png
set pm3d map
set xtics font "Times-Roman, 16"
set xlabel "Tempo (dias)" font "Times-Roman, 24"
set ytics font "Times-Roman, 16"
set ylabel "Escala" font "Times-Roman, 24"
set xrange [0:aux2]
set palette rgbformulae 22,13,-31
set cbtics font "Times-Roman, 16"

set output "original.png"
splot "scalogram_original.txt" using (($2)/1440):1:3 notitle;

For quality issues, would generate the same map in eps terminal. Para isso, reescrevi os comandos acima do seguinte modo:

aux2=3129.0/1440

set term postscript eps enhanced color
set pm3d map
set xtics font "Times-Roman, 16"
set xlabel "Tempo (dias)" font "Times-Roman, 24"
set ytics font "Times-Roman, 16"
set ylabel "Escala" font "Times-Roman, 24"
set palette rgbformulae 22,13,-31
set cbtics font "Times-Roman, 16"

set output "original.eps"
splot "scalogram_original.txt" using (($2)/1440):1:3 notitle

But when I try to do this , I get the following warning: ""escalogramaeps.gp", line 15: All points x value undefined"

I can not find my mistake. I am a novice user in gnuplot .

Can someone help me? Thanks in advance.

Att.
Luciano.
