我试图将网格放入我的图形中,但出现了下面的问题。网格样式必须是辅助线和虚线,我知道该怎么做,但问题仍然存在,无法正确放置网格。
这是我正在使用的代码。
\documentclass[a4paper,10pt]{article}
\usepackage{pgfplots}
\usepackage{filecontents}

\pgfplotsset{

}
\begin{tikzpicture}
% provide shared options here with pgfplotsset:

% this is the leftmost y axis (y2)

我找到了一种方法来做到这一点。
