gnuplot显示问题 - 红帽子

Question

我有一个gnuplot脚本来跟踪某些参数随时间的变化。这适用于我们的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 multiplot

    unset multiplot

当我在我的机器上运行时，我得到以下输出

为什么这么乱？当我单击切换网格按钮时，我失去了4个图中的3个，但是一个图看起来更像它应该。

以下是test命令的输出。看起来很好

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