我正在使用GNUPLOT的splot函数来显示两个独立变量的值。然而，大部分数据，a）我不感兴趣，和b）我最终想要删除＆＃34;设置视图地图＆＃34;并且只能看到我感兴趣的数据部分作为3D投影。目前，有太多的表面可以真正看到我想要的情节部分，它们落在盆地内。
我想只显示沿x = y的数据，可能在任一方向上都有一个单位的方差，所以更多的是一个数据带而不是只有一条直线上的数据。它将从（0,0）开始并在（6,6）附近结束。
我的基本GNU代码是：
set palette rgbformulae 30,31,32
set size square
set view map
splot 'free_energy.dat' using 1:2:3 with pm3d
不幸的是，我还没有发布图片的10个声望点，所以这里是splot图片的链接：
数据文件非常庞大，因此我非常不愿意解析或删除数据本身。列的一个非常小的例子可以在下面看到。我只对d.y（x），dRMSD（y）和file.free（因变量）感兴趣。
#! FIELDS d.y dRMSD file.free der_d.y der_dRMSD
#! SET min_d.y -8.01552
#! SET max_d.y 7.99331
#! SET nbins_d.y 92
#! SET periodic_d.y false
#! SET min_dRMSD -1.69088
#! SET max_dRMSD 12.5407
#! SET nbins_dRMSD 82
#! SET periodic_dRMSD false
-8.015520000 -1.690880000 1588.947840498 -0.000000000 -0.000000000

沿x = y线切割。稍后您可以改变它，例如：
splot 'free_energy.dat' using 1:2:(($1<$2)?3:1/0) with pm3d
