![3D 中的 Z 轴刻度](https://linux22.com/image/471819/3D%20%E4%B8%AD%E7%9A%84%20Z%20%E8%BD%B4%E5%88%BB%E5%BA%A6.png)
我正在重新创建该图表。
我不太清楚如何缩放 z 轴以使其看起来像这样。
这是我目前所拥有的:

答案1
只是一个建议,但也许 Ti钾对于该图来说,Z 比 PGFPlots 更好吗?
isometric view
您可以使用库中的表单解决问题perspective
。其余的在 Ti 中更容易钾Z 保存蜱虫,但您可以使用\pic
该任务。
例如:
\documentclass[tikz,border=1.618mm]{standalone}
\usetikzlibrary{3d,perspective}
% colors, styles and a \pic for the tikcs
\definecolor{blue1} {RGB}{066,127,187}
\definecolor{purple1}{RGB}{177,015,189}
\tikzset
{
point/.style={circle,fill,inner sep=0.4mm},
pics/tick/.style=
{
/tikz/transform shape,
code=
{
\draw (0.05,0) --++ (-0.1,0);
\draw (0,0.05) --++ (0,-0.1) node[pos=3,transform shape=false] {$#1\ifnum#1<0\phantom{-}\fi$};
}
}
}
