例如从左到右的一个有向图
graph LR;
A[aa bb]-->B(wo);
A-->C((我是C));
B-->D>我是D];
C-->D;
D-->E{我是E};
C-->E;
2-->E;
_-->E;
第一行的graph LR
中graph
指定是一个图,第二个LR
指定图的方向,所有的方向关键词为:
TB - top bottom
BT - bottom top
RL - right left
LR - left right
TD - same as TB
之后的A,B,C等都是节点的标识(标识中不能使用空格)
节点默认只显示标识,但也可以通过如下方法控制其显示
A[aa bb]
显示字符串aa bb
的方框
B(wo)
显示字符串wo
的圆角框
C((我是C))
显示我是C
字符串的圆圈
D>我是D]
显示我是D
的半方框
E{我是E}
显示我是E
的正方形框
连线可以选择如下形式:
A-->B
箭头
A--B
无箭头线
A--hh dd--B
或者A--|hh dd|B
线之间可以添加注释
A-.->B
虚线箭头
A-. hh .->B
添加了注释的虚线箭头
A==>B
加粗的箭头
A== hh ==>B
加注释加粗的箭头
子图可以使用subgraph id
定义
graph TB
subgraph one
a1-->a2
end
subgraph two
b1-->b2
end
subgraph three
c1-->c2
end
c1-->a2
使用如下语法给节点添加点击行为
click nodeId callback
callback
是javascript
回调函数
修改节点的显示样式
graph LR
id1(Start)-->id2(Stop)
style id1 fill:#f9f,stroke:#333,stroke-width:4px;
style id2 fill:#ccf,stroke:#f66,stroke-width:2px,stroke-dasharray: 5, 5;
或者使用如下方式修改class
class nodeId1 className;
class nodeId1,nodeId2 className;
classDef default fill:#f9f,stroke:#333,stroke-width:4px;
如下是一个基本的时序图
sequenceDiagram
participant Alice
participant Bob
Alice->John: Hello John, how are you?
loop Healthcheck
John->John: Fight against hypochondria
end
Note right of John: Rational thoughts <br/>prevail...
John-->Alice: Great!
John->Bob: How about you?
Bob-->>John: Jolly good!
时序图使用sequenceDiagram
关键词声明
参与者使用participant
声明
消息声明是使用[参与者][发送方式][参与者]:消息内容
形式声明
发送方式有如下几种:
->
无箭头的线
-->
无箭头的虚线
->>
有箭头的实线
-->>
有箭头虚线
-x
有十字叉的实线
--x
有十字叉的虚线
可以通过ote right of [参与者]: 信息
的方式添加备注(多行信息请使用<br/>
)
添加循环
loop Loop text
... statements ...
end
添加判断使用如下语法
有选择的:
alt Describing text
... statements ...
else
... statements ...
end
确定的:
opt Describing text
... statements ...
end
示例:
sequenceDiagram
Alice->>Bob: Hello Bob, how are you?
alt is sick
Bob->>Alice: Not so good :(
else is well
Bob->>Alice: Feeling fresh like a daisy
end
opt Extra response
Bob->>Alice: Thanks for asking
end
