GNUplot 热图中的标签值

我正在尝试使用 gnu plot 生成热图。

set title "Heat Map"

plot '-' matrix with image

10  20  30  40  50  60  70  80  90  100

图像生成

沿着轴，我得到值 -2 0 2 4 6 8 10，我想用自定义字符串替换它们。我不知道如何做到这一点。

尝试这个解决方案：

set border 0 # remove box around map
set xtics ("first" 0, "sec." 2, "last" 9) # set special strings on selected position on x axes
set ytics ("first" 0, "sec." 2, "last" 9) # set special strings on selected position on y axes
unset key # without key

set title "Heat Map"
plot '-' matrix with image
