我想使用gnuplot在图形中表示信息，但我遇到了问题，因为gnuplot在执行时发送了一个错误。 我把代码表：
Tablas.txt 的

这是我的gnuplot脚本代码。我使用：
执行它ejemplo_gnuplot.sh 的
#!/bin/bash
cat << _end_ | gnuplot
set terminal postscript eps color
set output "grafico.eps"
set key right bottom
set xlabel "Etiqueta eje X"
set ylabel "Etiqueta Eje Y"
plot 'tablas.txt' using 1:2 t "Datos columna 2 frente a 1" w l, 'tablas.txt' using 1:3 t "Datos columna 3 frente a 1" w l, 'tablas.txt' using 1:5 t "Datos columna 5 frente a 1" w l, 'tablas.txt' using 1:6 t "Datos columna 6 frente a 1" w l
_end_
这是脚本执行的输出
ejecutar script
./ejemplo_gnuplot.sh

有人可以帮我解决问题，请问？ 感谢
