如果y列的线条样式发生变化，则在多重图中更改网格线。
提问于 2016-01-09 04:24:51
我试图在png文件中绘制多个情节。多重图有8个图元。每幅图都有两个y轴，网格将用ls 0显示.一切都很好，直到我改变了一个情节的线宽。当我在绘图中直接更改线型或线宽时，其余图形中的网格将以新的线宽和颜色显示。我在Windows 7 MinGW中使用GNU绘图版本5。
我已经尝试过在网格中设置行样式，如下所示：
- set style line 4 lc rgb 'black' lt 0 set grid xtics ytics y2tics ls 4
- 在绘图时设置线宽，如下所示: input_filename使用11:9和线轴x1y2 lc rgb‘绿色’lw2标题‘plt-5’
但什么都不管用。以下是完整的代码：

unset multiplot和pngcairo合作。下面是供参考的最终代码。谢谢Schorsch。

我相信你的问题与你设定的线条风格有关：
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由于有预定义的线条样式，这些样式可能无法正常工作，最终会使您的网格线在多重绘图环境中混乱。更具体地说，是选项lw 2打破了您的网格线。
对于 output，您可以看到有80种预定义的行样式：
因此，将上述行更改为
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命令以引用这些行样式编号，您将得到以下情节：
调试备注：
- 真正看起来搞糟情节的是
lw 2选项。奇怪的是，如果您使用lw 3指定了网格线，它们将不会受到影响(但也会比您希望的更厚)。 - 各种组合中的
dashtype选项也不会解决您的问题。对于网格线，它完全被忽略了。 - 除了一种预定义的行类型之外，任何东西都会导致此问题。您可以选择
lt 8，并获得坚实的黑色网格线。 - 您可以考虑使用不同的终端：
set terminal pngcairo对于不同的终端，您的原始脚本的行为与预期相同。
