动画节点标签

Question

我有一个简单的 Ti钾Z 节点

\begin{tikzpicture}
\matrix (magic) [matrix of nodes,ampersand replacement=\&, column sep=6mm, row sep=5mm]{
    \node (DT) [draw,shape=rectangle, rounded corners,visible on=<2->]{Source de données}; \\
    \node (IF) [draw,shape=rectangle, rounded corners,visible on=<3->] {Items fréquents}; \\
    \node (FER) [draw,shape=rectangle, rounded corners,visible on=<4->] {Fermetures}; \\
    \node (SUB) [draw,shape=rectangle, rounded corners,visible on=<5->] {Sous-ensembles des fermetures}; \\
    \node (ISC) [draw,shape=rectangle, rounded corners,visible on=<6->] {Itemsets cycliques}; \\
    \node (RAC) [draw,shape=rectangle, rounded corners,visible on=<7->] {Régles d'association cycliques}; \\
};
    \draw[->, thick,visible on=<3->] (DT) -- (IF);
    \draw[->, thick,visible on=<4->] (IF) -- (FER);
    \draw[->, thick,visible on=<5->] (FER) -- (SUB);
    \draw[->, thick,visible on=<6->] (SUB) -- (ISC);
    \draw[->, thick,visible on=<7->] (ISC) -- (RAC);
\end{tikzpicture}

我只需要为每个节点在右侧制作一个标签，该标签出现在节点出现时（而不是之前或之后）。
