format定义了语句块的颜色、形状和边,test定义了条件块的形状(菱形)和颜色等,point是像素点,用于连接转移线。有时我们会发现条件块的语句太长,可以在定义里指定条件块的宽度,这样编译出来的图形里的文字会自动换行,比如说
\tikzstyle{test}=[diamond,aspect=2,draw,thin,text width=2cm]
start chain=going below指明了流程图的默认方向,node ditance=8mm则指明了默认的node距离。这些可以在定义node的时候更改,比如说
\node[point,right of=n3,node distance=10mm] (p0){};
这里声明了node p0,它在node n3 的右边,距离是10mm。
定义完node之后画线。线可以是实线、虚线、曲线等,也可以带箭头和不带箭头。
箭头

\node[format] (n0){A};
\node[format,below of=n0] (n1){B};
\draw[->] (n0.south) -- (n1);
\end{tikzpicture}
\end{figure}
不带箭头

双箭头和虚线

\draw[<->] (n0.south) -- (n1.north);
\draw[<-,dashed] (n1.south) -- (n2.north);

带文字的线

\draw[<-] (n0.south) to node{Yes} (n1.north);
\draw[<-,dashed] (n1.south) -- (n2.north);
\end{tikzpicture}
\end{figure}
文字总是在箭头方向的右边,如果想让文字在左边可以这样做,
\draw[->] (n1.north) to node{Yes} (n0.south);
