使用 gnuplot 等高线以外的等高线图
Contour plot other than contour lines with gnuplot
我已经用我的数据生成了等高线图 Data to plot. The output looks like contour lines。我现在正在尝试用颜色填充等高线图。之前有一个post关于它
http://gnuplot-tricks.blogspot.com/2009/07/maps-contour-plots-with-labels.html
我已经按照说明修改为：
set xrange [0:32]
set yrange [0:32]
set table 'test.dat'
splot "contour.dat"
unset table
set contour base
set cntrparam level incremental 0, 0.1, 1
unset surface
set table 'cont.dat'
splot "contour.dat"
unset table
reset
set xrange [0:32]
set yrange [0:32]
unset key
set palette rgbformulae 33,13,10
p 'test.dat' with image, 'cont.dat' w l lt -1 lw 1.5
但是我的情节是这样的after new code。 gnuplot 显示警告，输出消息为
warning: Cannot contour non grid data. Please use "set dgrid3d".
warning: Skipping data file with no valid points
我已经设置了，但是外观还是没有变化。
现在的问题是缺少或应该使用哪个选项或命令来获取彩色填充等高线图？我也在看书https://www.manning.com/books/gnuplot-in-action-second-edition
但还是找不到那种情节的命令。

以下适用于我 (gnuplot>=5.0.3)。
绘制您的文件，例如通过 splot FILE matrix 进入数据块 $Contour。
然后在 for 循环中绘制文件 matrix with image 和轮廓线。
也许有更好的解决方案。
代码：（您的数据保存为文件SO70759953.dat）
### plot matrix with contours
reset session
FILE = 'SO70759953.dat'
set size square
set xrange [0:31]
set yrange [0:31]
set contour base
set cntrparam level incremental 0, 0.2, 1.0
set table $Contour
splot FILE matrix
unset table
set palette rgbformulae 33,13,10
set key out title "Levels"
plot FILE matrix with image notitle, \
for [i=1:*] $Contour index i w l lt i lw 1.5 ti columnhead(3)
### end of code
结果：
我可能误解了请求...您是否要求平滑等高线图，其中 pm3d 颜色对应于离散等高线范围？
set view map
set xrange [*:*] noextend
set yrange [*:*] noextend
set pm3d interpolate 9,9
set palette maxcolors 10
set palette rgbformulae 33,13,10
splot 'matrix.dat' matrix with pm3d notitle
当矩阵分辨率仅为32x32时，很难获得平滑的轮廓边缘。如果您退回到仅 5 个等高线级别，可能会好一点：
我已经用我的数据生成了等高线图 Data to plot. The output looks like contour lines。我现在正在尝试用颜色填充等高线图。之前有一个post关于它 http://gnuplot-tricks.blogspot.com/2009/07/maps-contour-plots-with-labels.html 我已经按照说明修改为：
set xrange [0:32]
set yrange [0:32]
set table 'test.dat'
splot "contour.dat"
unset table
set contour base
set cntrparam level incremental 0, 0.1, 1
unset surface
set table 'cont.dat'
splot "contour.dat"
unset table
reset
set xrange [0:32]
set yrange [0:32]
unset key
set palette rgbformulae 33,13,10
p 'test.dat' with image, 'cont.dat' w l lt -1 lw 1.5
但是我的情节是这样的after new code。 gnuplot 显示警告，输出消息为
warning: Cannot contour non grid data. Please use "set dgrid3d".
warning: Skipping data file with no valid points
我已经设置了，但是外观还是没有变化。
现在的问题是缺少或应该使用哪个选项或命令来获取彩色填充等高线图？我也在看书https://www.manning.com/books/gnuplot-in-action-second-edition 但还是找不到那种情节的命令。

以下适用于我 (gnuplot>=5.0.3)。
绘制您的文件，例如通过 splot FILE matrix 进入数据块 $Contour。
然后在 for 循环中绘制文件 matrix with image 和轮廓线。
也许有更好的解决方案。
代码：（您的数据保存为文件SO70759953.dat）
### plot matrix with contours
reset session
FILE = 'SO70759953.dat'
set size square
set xrange [0:31]
set yrange [0:31]
set contour base
set cntrparam level incremental 0, 0.2, 1.0
set table $Contour
splot FILE matrix
unset table
set palette rgbformulae 33,13,10
set key out title "Levels"
plot FILE matrix with image notitle, \
for [i=1:*] $Contour index i w l lt i lw 1.5 ti columnhead(3)
### end of code
结果：
我可能误解了请求...您是否要求平滑等高线图，其中 pm3d 颜色对应于离散等高线范围？
set view map
set xrange [*:*] noextend
set yrange [*:*] noextend
set pm3d interpolate 9,9
set palette maxcolors 10
set palette rgbformulae 33,13,10
splot 'matrix.dat' matrix with pm3d notitle
当矩阵分辨率仅为32x32时，很难获得平滑的轮廓边缘。如果您退回到仅 5 个等高线级别，可能会好一点：
