Question

我想用AIX 7.2和Gnuplot 4.6创建一个Gnuplot脚本

我的脚本是：


set terminal png truecolor size 1950, 650  background rgb "#eff1f0"
set output "/home/tbenedet/GNUPLOT/used.png"
set datafile separator ';'

set size ratio 0.2
set bmargin at screen 0.2
unset key
set datafile separator ";"
set ylabel " MB BLOCK " font ",10" offset -1,0
set xlabel font ",10"
set xtics rotate by 45  offset -0.8,-9,-1.8


plot "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \

     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \
     "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5

乍一看，我的脚本是正确的...但是当我尝试使用gnuplot myscript.txt运行它时，出现了这个错误：

plot "/var/xxx/xxx/xxx/xxx/xxx/xxx/xxx/foo.txt" using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \ using 3:xtic(1) title column(2) with linespoints linewidth 2 pointtype 7 pointsize 1.5, \ 
                                                                                                                                                                           ^
"myscript.txt", line 14: invalid character \

我不知道是我的错误吗？你能告诉我吗？

谢谢

您的绘图命令的长度约为3600个字符。我不确定是否有长度限制，或者至少必须超过10'000，因为我尝试了类似的命令，并使用了超过10'000个字符，但没有收到您的错误消息。顺便说一句，如果您不知道，可以缩短几个关键字：using到u，title到ti，with到w，linespoints至lp，linewidth至lw，pointtype至pt和pointsize至{ {1}}

我猜（正如Lorinczy Zsigmond已经提到的那样），您在ps之后有一些“不可见”字符，它也可能是\或empty space。一些合理的文本编辑器可以使“不可见”字符变为“可见”。检查同一行中TAB之后是否有任何字符。

来自gnuplot手册。选中\：

命令可以通过在每行末尾加上反斜杠（）来结束几行输入。反斜杠必须是每行上的 last 字符。效果就像没有反斜杠和换行符。即，不暗示空格，也不终止评论。因此，注释掉一条连续的行注释掉整个命令（请参见注释）。但是请注意，如果在多行命令的某处发生错误，则解析器可能无法准确定位错误所在的位置，在这种情况下，不一定指向正确的行。

Gnuplot：我的脚本似乎不错，但出现错误“无效字符\”
