我有一个 gnuplot 脚本来跟踪某些参数随时间的变化。这适用于我们 linux 网络上的所有桌面，除了一个：

这是代码和输出

        gnuplot -geometry 1024x768 -persist << EOF

    set datafile separator ","
    set datafile missing ""
    set size 1.0, 1.0
    set origin 0.0, 0.0
#   set key at 0,0
    set key spacing 1.3
    set key horiz ins top center box lw 0
    set border 3

    set multiplot
    set size 0.45,0.45
    set origin 0.02,0.02 #bottom left Tl H2
    set grid

    set xdata time
    set timefmt "%d/%m/%y"
    #   set xtics format "%d/%m/%y" 
    set xrange ["$thirty_days_ago":"$todays_date_4_2"]
    set xtics rotate nomirror
    set xtics "$thirty_days_ago",172800,"$todays_date_4_2"

    set yrange [0:30]
    set ytics nomirror
    set title "Tl201 CFOV $l H2" font "Helvetica"
    plot \
        '/misc/${camera2}_data/${camera2}/${qc}/tl_h2_qc_s' using 1:17  pt 5 ti ' NEMA Diff (%)' with linespoints,\
        '/misc/${camera2}_data/${camera2}/${qc}/tl_h2_qc_s' using 1:16 lt 3 pt 5 ti 'NEMA Int (%)' with linespoints,\
        '/misc/${camera2}_data/${camera2}/${qc}/tl_h2_qc_s' using 1:12 lt 4 pt 5 ti 'CoV (%)' with linespoints

    set origin 0.02,0.52 #top left Tl H1
    set title "Tl201 CFOV $l H1"
    if ("$camera2" eq "blue1" || "$camera2" eq "red1") plot \
        '/misc/${camera2}_data/${camera2}/${qc}/tl_h1_qc_s' using 1:17  pt 5 ti ' NEMA Diff (%)' with linespoints,\

    set origin 0.52,0.02 #bottom right Tc H2
    set title "Tc99m CFOV $l H2"    
    plot \
        '/misc/${camera2}_data/${camera2}/${qc}/tc_h2_qc_s' using 1:17  pt 5 ti ' NEMA Diff (%)' with linespoints,\
        '/misc/${camera2}_data/${camera2}/${qc}/tc_h2_qc_s' using 1:16 lt 3 pt 5 ti 'NEMA Int (%)' with linespoints,\
        '/misc/${camera2}_data/${camera2}/${qc}/tc_h2_qc_s' using 1:12 lt 4 pt 5 ti 'CoV (%)' with linespoints

    set origin 0.52,0.52 #top right
    set title "Tc99m CFOV $l H1"    
    if ("$camera2" eq "blue1" || "$camera2" eq "red1") plot \

        '/misc/${camera2}_data/${camera2}/${qc}/tc_h1_qc_s' using 1:12 lt 4 pt 5 ti 'CoV (%)' with linespoints

    unset multiplot


EOF

当我在我的机器上运行它时，我得到以下输出在此处输入图像描述

为什么这么乱？当我单击切换网格按钮时，我丢失了 4 个图中的 3 个，但一个图看起来更像它应该的。在此处输入图像描述

这是测试命令的输出。看起来不错 在此处输入图像描述

这似乎不是 gnuplot 的问题，而是我的 linux 设置。我正在运行 RedHat Client 5.8 版。任何想法这里发生了什么
