带有标示高度的线条的圆柱体

有什么建议关于如何在圆柱体中放置一些线（如刻度）来指示圆柱体的高度？

它看起来应该是这样的： 在此处输入图片描述

这是我的 MWE：

干得好：

        main node/.style={
            circle,
            fill=gray!25,
            draw,
            font=\sffamily\footnotesize

        cylinder node/.style={

        },
    }
}

        \foreach \y in {0,5,...,\maxht}{

这是另一个版本，它将平均划分高度

    node_standard/.style = {
        ->,>=stealth',shorten >=1pt,node distance=2.5cm,auto,thick,
        main node/.style={
            circle,
            fill=gray!25,
            draw,
            font=\sffamily\footnotesize
        },
        cylinder node/.style={
            name=cyl,   %% named here
            shape=cylinder,   %% slightly changed
            draw=black,
            thick,
            aspect=0.9,
            minimum width=0.8cm,
            shape border rotate=90,
            anchor=bottom,
            font=\sffamily\footnotesize,
            cylinder uses custom fill,
            cylinder body fill=gray!15,
            cylinder end fill=gray!25,
            text height=0.08cm
        },
        height4/.style={
            minimum height=20mm,   
                   },
    }
}

\begin{document}
    \begin{tikzpicture}[node_standard]
        \node[cylinder node,height4]       {$a$};
        \foreach \y in {0,0.05,...,1}{
          \draw[-,very thin] ($(cyl.after bottom) !\y! (cyl.before top)$) -- +(1mm,0);
          }
        \foreach \y in {0,0.25,...,1}{
          \draw[-,thin] ($(cyl.after bottom) !\y! (cyl.before top)$) -- +(1.4mm,0)node[scale=0.25,anchor=west,inner sep=0pt,xshift=-3pt]{\SI{\y}{\milli\liter}};
          }
    \end{tikzpicture}

\end{document}

如果你只想要以下几行：

\begin{tikzpicture}[node_standard]
\xdef \maxht{20}
\node[cylinder node,height4]       {$a$};
\foreach \y in {0,.1,...,1}{
  \draw[-,thin] ($(cyl.after bottom) !\y! (cyl.before top)$) -- +(2mm,0);
  }
\end{tikzpicture}

    \begin{tikzpicture}[node_standard]
        \path pic {ticks={height4}{5}{a}};

答案2

您可以将以下内容添加到您的\tikzpicture：

\draw[|<->|]([xshift=6mm,yshift=-2mm]1.north)--node[right]{$s$}([xshift=6mm]1.south) ;
