知乎 用什么軟件畫流程圖?
說到流程圖還是再次提及一下,我們之前說到的Graphviz 。
Graphviz (英文:Graph Visualization Software的縮寫)是一個由AT&T實驗室啟動的開源工具包,用於繪制DOT語言腳本描述的圖形。它也提供了供其它軟件使用的庫。
它的主要特點是代碼生成圖像,並且足夠的簡單。
2.Graphviz
(1)下載安裝
http://graphviz.org/Download.php 最下方 agree
Windows
Stable and development Windows Install packages
(2)添加環境變量
path添加: D:\Program Files (x86)\Graphviz2.38\bin
新開cmd:dot -?
(3)中文支持

只要你用 UTF-8 的編碼來儲存描述關係圖的 dot 檔,Graphviz 也可以產生包含中文的關係圖。但 Windows 版的 Graphviz 似乎沒有設定好 fontconfig,因此會找不到中文字型,只要設定好 fontconfig 即可解決。依照預設安裝路徑,設定檔在 C:\Program Files\Graphviz 2.21\etc\fonts\fonts.conf,找到以下這行: <dir>#FONTDIR#</dir> 改成 Windows 字型檔的路徑: <dir>C:\WINDOWS\Fonts</dir> Graphviz 就可以使用中文了!但注意目前似乎只能輸入英文的字型名稱,範例如下: digraph g { node[fontname = "PMingLiu"]; "中文" -> "英文"; }
(4) 可以運行gvedit.exe寫入代碼,f5直接預覽效果
(5) python庫,其實用處不大
https://pypi.python.org/pypi/graphviz
3.參考文檔
官網: http://graphviz.org/Documentation.php
一次性批量定義屬性
node [color=Red,fontname=Courier,shape=box] //All nodes will this shape and colour edge [color=Blue, style=dashed] //All the lines look like this
標 題: 【合集】dot language Graphviz流程圖的問題
(連線連在角上)
portPos headport tailport 這幾個屬性
digraph login3times{ edge[fontname="Microsoft YaHei"] node[shape=box, fontname="Microsoft YaHei" size="20,20"] fontname="Microsoft YaHei" label="三次登錄流程圖"
4.語法注意事項
(1)框圖為node,默認形狀 ellipse 橢圓形, shape = box 長方形,diamond 菱形,circle 圓形
(2)連線為edge,箭頭方向 [dir=forward, back, both, or none]
(3)在有必要的時候加雙引號,如:“do sth”, "func()"
(4)注釋為 //, 或 /* */
(5)不方便之處:
A -> B -> C ->D[label=to] ,則會在三條連線上都添加 to 字樣
對比:
A -> B
B -> C[label=to]
C ->D
5.綜合應用

//G:\pydata\pycode>dot eg.dot -Tpng -o eg.png digraph graphname { //rankdir=LR node[fontname = "simsun"] fontname="Microsoft YaHei" label="代理IP獲取流程圖" START[label="入口get_mimvp()" shape=box] END[label=出口ip_port_type_tuple_list, shape=box] JUDGE[label="feature_vectors == []" color=Blue, fontsize=24, shape=diamond] START -> JUDGE {rank=same; "extract_features()", "load_mimvp()"} JUDGE -> "extract_features()"[label=True tailport=w]// headport=n] "extract_features()"[style=filled, fillcolor=orange] JUDGE -> "load_mimvp()"[label=False tailport=s headport=n] "extract_features()" -> "load_mimvp()"[label=return, fontcolor=red, dir=forward] //dir=forward, back, both, or none port_src_list[style=filled, fillcolor=yellow] port_list[style=filled, fillcolor=green] "load_mimvp()" -> {ip_list, type_list, port_src_list} port_src_list -> port_list {rank=same; ip_list, type_list, port_list} -> "merge_result" -> END subgraph cluster1 { label=子圖1_特征提取 "invoke extract_features()"[style=filled, fillcolor=orange] judge[label="filepath is not None" color=Blue, shape=diamond] feature_vectors[style=filled, fillcolor=red] "invoke extract_features()" -> judge judge -> "load_images_from_filepath()"[label=True tailport=w] judge -> "load_images_from_src_list()"[label=False tailport=s] {rank=same; "load_images_from_filepath()", "load_images_from_src_list()"} "load_images_from_filepath()" -> "split_image()"[label=img_list] "load_images_from_src_list()" -> "split_image()"[label=img_list] "split_image()" -> "build_vector()"[label="split_imgs"] "build_vector()" -> feature_vectors[label="item = {input: vector}"] // -> "load_mimvp()" } subgraph cluster2 { label=子圖2_余弦相似度比較 port_src[style=filled, fillcolor=yellow] port[style=filled, fillcolor=green] port_src -> "get_port()" -> "load_image_from_src()" -> "invoke split_image()" -> "invoke build_vector()" "invoke build_vector()" -> "cos_similarity()"[label="vector\nfeature_vectors", fontcolor=red] "cos_similarity()" -> port } }
代碼另存為eg.dot, 編碼utf-8
在命令行中運行:G:\pydata\pycode>dot eg.dot -Tpng -o eg.png
