四边都有坐标的彩色网格？

四边都有坐标的彩色网格？

这是一个稍微增强版本的请求问题的答案：“所有边都有坐标的网格？”，这本身是对@Loopspace 先前答案的增强。

我想要第一个版本代码的彩色网格版本，位于问题的开头。链接的答案包括三个版本，以便于衡量。我认为对于熟悉 PGF/TikZ 相关部分的人来说，这很容易。为了具体起见，我们假设为浅绿色/叶绿色。我想要整个网格都是绿色，除了数字。

动机：我使用此网格代码来注释 PDF 表单。我想尝试使用不同于黑色的颜色，尤其是绿色，因为我认为绿色会与通常为黑白的实际表单形成对比

谢谢。

您可以直接在样式定义中添加颜色，也可以在生成网格时将其附加到样式中。在此代码中，我展示了后一种解决方案。我已将该tikz选项作为全局选项删除，以便我可以xcolor使用dvipsnames那些命名颜色的选项进行加载（在 之前加载tikz）。

这是一个基于不带版本\pgfextra，理由是 pgfmanual v.3.1.4\pgfextra在第 167 页提到

请注意，此操作仅应由真正的专家使用，并且仅应在巧妙的宏内部深处使用，而不能在正常路径上使用。

这也是一种“清理”键的尝试，以便所有内容都在目录下/tikz/grid with coordinates/。它现在有键all help lines，它为次要和主要帮助行添加了一些样式。此外，语法也已尝试清理，灵感来自这次讨论：现在你只需要说一遍ticks/.list={top,left}而不用再说好true几遍。

color=green,可以通过添加minor help lines/.style=和来调整网格线的颜色major help lines/.style=。
