如果更改 y 列的线条样式，则多图中的网格线会更改
grid lines are changed in multiplot if lines styles of y column is changed
我正在尝试在 png 文件中绘制多图。 Multiplot 有 8 个地块。每个图都有两个 y 轴，网格将使用 ls 0 显示。一切正常，直到我更改图的线宽。当我直接在绘图中更改线型或线宽时，其余绘图中的网格将以新的线宽和颜色显示。我在 Windows 7 MinGW 中使用 GNU Plot 版本 5。
我已经尝试过在网格中设置线条样式，如下所示：
1。
设置样式行 4 lc rgb 'black' lt 0
设置网格 xtics ytics y2tics ls 4
- 绘图时设置线宽，如下所示：
input_filename using 11:9 with lines axes x1y2 lc rgb 'green' lw 2 title 'Plot-5'
但没有任何效果。以下是完整代码：

我认为您的问题与您设置的线条样式有关：
set style line 1 lc rgb 'red' lt 3
set style line 2 lc rgb 'blue' lt 2 lw 2
set style line 3 lc rgb 'green' lt 1
set style line 4 lc rgb 'black' lt 0
由于有预定义的线型，这些线型可能无法正常工作并最终弄乱多图环境中的网格线。更具体地说，是选项 lw 2 打断了您的网格线。
Printing a test output 对于 png terminal 你可以看到有 80 种预定义的线条样式：
因此，将上面的行更改为
set style line 81 lc rgb 'red' lt 3
set style line 82 lc rgb 'blue' lt 2 lw 2
set style line 83 lc rgb 'green' lt 1
set style line 84 lc rgb 'black' lt 0
并修改脚本中的 plot 命令以引用这些线条样式编号，您将得到此图：
调试备注：
真正让情节混乱的是 lw 2 选项。奇怪的是，如果您使用 lw 3 指定网格线，它们不会受到影响（但也会比您想要的粗）。
各种组合中的 dashtype 选项似乎也无法解决您的问题。对于网格线，它被完全忽略。
除了一种预定义的线型之外，任何其他线型都会导致此问题。您可以选择 lt 8 并获得黑色实心网格线。
您可以考虑使用不同的终端：
`set terminal pngcairo`
使用不同的终端，您的原始脚本会按预期运行。
