gnuplot:来自同一曲线图中两个不同文件的轮廓和热图 [英] gnuplot: contour and heatmap from two different files in the same splot

问题描述

我正在尝试使用以下代码绘制两个2D标量，一个作为热图，一个作为叠加轮廓.

I am trying to plot two 2D scalar quantities, one as a heatmap and one as superimposed contour, using the following code:

set contour base
set cntrparam levels incremental 0,0.25,1.25
unset surface
set table cont2.dat
splot 'vr245.gnu'
unset table
reset
set xrange [1:215]
set yrange [0:3.1415925025940E+00]
set cbrange [7:17]
unset key
set view map
set palette rgbformulae 33,13,10
splot 'f_aveFe_245.gnu' u 1:2:3 with pm3d, "cont2.dat" u 1:2:3 w l

如您所见，轮廓在左侧有伪影.我该如何解决这个问题?谢谢！

As you can see the contour has artifacts on the left. How can I fix this problem? Thank you!

推荐答案

您可以为一个绘图中的各个绘图选择性地打开或关闭曲面的轮廓绘制.在脚本中定义pm3d和contours，停用第一个轮廓，并禁用

You can selectively switch on or off contouring and plotting of the surface for individual plots in a single splot. Define both pm3d and contours in the script, deactivate contours for the first and surface for the
