我想画一个图表。我不知道怎么画。谁能告诉我怎么做？
答案1
这是我的方法。我尝试使用以下方法获取线条的数据点这个在线工具并使用 Excel 进行潜在拟合以获取函数。然后，我将线条添加到 -plot loglog。对于标签，您可以\draw结合使用(axis cs:x,y)以使用绘图坐标对齐它们。
\documentclass[border=5pt]{standalone}

\pgfplotsset{

log ticks with fixed point,

\begin{document}
\begin{tikzpicture}

\addplot[

\addplot[

我稍微修改了代码以满足您的需要。

你的问题：
问题 1 x 轴和 y 轴的数字应该如何增加？我的意思是，在原始图中我有 1、2、3、5、10.....，而实际上我们有 0.01、0.1、1、10、100。我想输入 1、2、3、5、10....我该怎么做？x 轴数字在两边。如何将数字放在两边？
我添加了一些extra y ticks和extra tick labels并删除了其他标签。第二个轴可以用虚拟图和来生成ylabel pos=right。
第二季度 原始图中斜线之间有数字，我应该如何输入这些数字？
您只需使用 向图表添加带有标签的节点即可添加这些数字(axis cs:x pos,y pos)。我想到了一种循环方法，使用
\foreach \y [count=\i from 1] in {30,40,60,90}{%
\edef\temp{%
\noexpand \node[black,below right,font=\noexpand\tiny] at (axis cs:400,\y) {\noexpand\contour{white}{\i}};
}\temp
}
这\y是标签的 y 位置，\i是标签。您可以通过复制循环、将 y 值、x 值和命令更改count from为特定数字来更改此设置。
答案2
像您图片中那样完成的基本对数对数轴\pgfplots（按照@Zarko 的建议）：
\documentclass[border=1cm]{standalone}
\usepackage{pgfplots}
\pgfplotsset{log ticks with fixed point,}
\begin{document}
\begin{tikzpicture}
\begin{loglogaxis}[
xlabel=A,ylabel=K,
log basis x=10,
log basis y = 10,
xmin=0.001, xmax=1000,
ymin=0.001, ymax=100,
grid=both,
x post scale=2, %switch this off if you do not want your x axis scaled
]
\end{loglogaxis}
\end{tikzpicture}
\end{document}
