GraphViz常用屬性學(xué)習(xí)筆記

1、GraphViz 常用屬性Inportant AttributesGraph Attributes label=My Graph;Label a graph itself rankdir=LR;Lay the graph out from Left to Right, instead of Top to Bottom rank=same; a, b, c Group nodes together at the same level of a graph splines=line;Force edges to be straight, no curves or angles K=0.6;Used

2、 to influence the spring used in the layout, Can be used to push nodes further apart, which is especially useful for twopi and sfdp layoutsVertex Attributes label=Some LabelLabels the Vertex color=redColors the Vertex fillcolor=blueFills the Vertex with the specified colourEdge Attributes label=Some

3、 LabelLabels the Edge (Useful for Weights) color=redColors the Vertex (Useful for Paths) Thickness=2.0 penwidth=2.0Adjusts the thickness of the edge line, Very useful for PathsEdges may also have aweightattribute, defined asweight=0.5for example, but note that this doesnt display the weight directly

4、, It instead acts as a hint to the graph layout to give this edge a more direct routing.Graph的定義graph node1 - node2;node3 - node2; digraph node1 - node2;node3 - node2; Vertices的定義可以先聲明其屬性，再使用digraph someVertexlabel=A Complicated Label;someVertex - node2;node2 - node3; 定義和使用線條，定義colour/thickness, lab

5、eldigraph node1 - node2color=red label=”edge1”;在Graph中定義edge和note的全局變量，以及支持中文輸入。Digraph GFontname=”FangSong”Fontcolor=”red”Label=”中文圖片”;Edge fontname = “FangSong”Nodeshape=”box” fontname=”FangSong” size=”10,10”;Alabel=”節(jié)點A”;Blabel=”節(jié)點B”;Clabel=”節(jié)點C”;使用rank定義排列位置rank=same; A, BA-B-C;vim中編輯graphviz文件并

6、生成圖片發(fā)表于3個月前(2016-01-31 11:30) 閱讀（77）|評論（3）2人收藏此文章,我要收藏贊04月23日，武漢源創(chuàng)會火熱報名中，期待您的參與摘要vim中編輯graphviz文件并自定義函數(shù)調(diào)用dot生成圖片寫一個zbjxb.vim文件，并將該文件放到vim的plugin目錄。linux下一般是/usr/share/vim/vim74/plugin/.linux下代碼為：function Dot(format) let fmt = a:format let cmd = dot let opt = -T . fmt . -o let currfile = expand(%:p)

7、let outfile = currfile . . . fmt silent execute !start . cmd . . currfile . . opt . . outfile . endfunctionwindows下代碼為：function Dot(format) let fmt = a:format let cmd = C:UsersGuestDownloadsProgram Files (x86)Graphviz2.30bindot.exe let opt = -T . fmt . -o let currfile = expand(%:p) let outfile = currfile . . . fmt silent execute !start . cmd . . currfile . . opt . . outfile . endfunction編寫完成后執(zhí)行vim命令，即可在該dot文件所在目錄下生成一張圖片：:call Dot(png)或者:call Dot(svg):call Dot(pdf)函數(shù)里的代碼也可以一行一行的執(zhí)行:echo comma
