创建环境而不是部分时遇到麻烦

我正在尝试找到一种方法来创建一个或多个环境，以便我可以创建类似我这里的东西，但自动对各部分进行编号并打印文本，例如步骤 1.....图表 1.....步骤 2.....图表 2......而不必全部输入，并使用图形等。这可能吗，还是我只是在浪费我和你的时间？

尝试

\newcounter{CountStep}
\newenvironment{diagram}
{\begin{center}\vspace*{10pt}\begin{tikzpicture}}
        {\end{tikzpicture}\vspace*{-5pt}\par\stepcounter{CountStep} Step=~\theCountStep\end{center}}

或者

\newcounter{CountStep}
\newcounter{CountDiag}
\newenvironment{diagram}
{\begin{center}\stepcounter{CountStep}\stepcounter{CountDiag}\vspace*{10pt} Step~\theCountStep\par\begin{tikzpicture}}
        {\end{tikzpicture}\vspace*{-5pt}\par Diagram~\theCountDiag
    \end{center}}
