graphviz便于数据可视化，用于生成决策树、流程图 Graphviz http://www.graphviz.org/ 安装brew ruby -e " $(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install) " 遇到错误可参考： mac上安装Homebrew及一些报错的处理 安装graphviz： brew install graphviz 文本保存为 hello.dot digraph pic { Hello -> World } 同一目录下终端运行 dot hello. dot -T png -o hello.png ͼƬ 新建编译系统，保存为 dot.sublime-build { " cmd ": [ "dot" , "$file" , "-T" , "png" , "-o" , "$file_base_name.png" ] , " working_dir ": "${project_path:${folder}}" , " selector ": "*.dot" } 用sublime打开上面的dot文件和编译完的图片文件，会下次编译后会自动更新 编译快捷键： command + B 参考 mac下的Graphviz安装及使用 Graphviz

doT.js可以更好的在html端使用json数据。 {{ }} for evaluation 模板标记符 {{= }} for interpolation 输出显示，默认变量名叫it {{! }} for interpolation with encoding 编码后输出显示 {{? }} for conditionals 条件分支， if条件的简写 {{~ }} for array iteration 遍历数组 引入js < script type= "text/javascript" src= "../script/doT.min.js"> </ script> <!-- jquery 移动端替代品 --> < script type= "text/javascript" src= "../script/zepto.min.js"> </ script> <!--<script type="text/javascript" src="../script/jquery.min.js"></script>--> 格式： {{= }} 数据源： {" name": "Jake"," age": 31} 区域: < div id= "interpolation"> </ div> 模板： < script id= "interpolationtmpl" type= "text/x

在使用可视化树的过程中，报错了。说是‘dot.exe’not found in path 原代码： # import tools needed for visualization from sklearn.tree import export_graphviz import pydot #Pull out one tree from the forest tree = rf.estimators_[5] # Export the image to a dot file export_graphviz(tree, out_file = 'tree.dot', feature_names = features_list, rounded = True, precision = 1) #Use dot file to create a graph (graph, ) = pydot.graph_from_dot_file('tree.dot') # Write graph to a png file graph.write_png('tree.png'); 报错信息： 解决方法： pip install pydot 然后再下载 Graphviz（ http://www.graphviz.org ）一路安装，记住默认的安装路径 c:\Program Files (x86)

SMOP SMOP 将matlab翻译成python。 SMOP 生成人类可读的蟒蛇，这似乎也比八度快。 速度有多快？ 表1显示了“移动家具”的计时结果。似乎对于该程序，转换为python导致加速大约两倍，并且 将 SMOP 运行时库 编译 runtime.py 实现了额外的两倍加速 。 这个伪基准测量标量性能，而我的解释是标量计算对八度组不太感兴趣。 源代码 Working example $ cd smop/smop $ python main.py solver.m $ python solver.py solver.m solver.m a.py 01 function mv = solver(ai,af,w) 01 def solver_(ai,af,w, nargout = 1 ): 02 nBlocks = max(ai(:)); 02 nBlocks=max_(ai[:]) 03 [m,n] = size(ai); 03 m,n=size_(ai, nargout = 2 ) 02 Matlab uses round brackets both for array indexing and for function calls. To figure out which is which, SMOP computes local use-def information

Rank attribute on edge has five values "same", "min", "source", "max", "sink". Except "same", I have no idea when to use other values. min \begin{dotpic} rankdir=LR; size="7,5"; node[shape=circle]; C->A; {rank=min;A;B} B->D A->B; \end{dotpic} max \begin{dotpic} rankdir=LR; size="7,5"; node[shape=circle]; C->A; {rank=max;A;B} B->D A->B; \end{dotpic} source \begin{dotpic} rankdir=LR; size="7,5"; node[shape=circle]; C->A; {rank=source;A;B} B->D A->B; \end{dotpic} sink \begin{dotpic} rankdir=LR; size="7,5"; node[shape=circle]; C->A; {rank=sink;A;B} B->D A->B; \end{dotpic} With test on my vim

I want to create a flowchart (similar to Visio) using Graphviz. Here is a sample digraph. digraph start_up { node [style = rounded]; node [shape = rect] start end; node [style = ""]; node [shape = diamond] "USB\nCommand\nArrived"; start -> "Initialize\nCode"; "Initialize\nCode" -> "USB\nCommand\nArrived"; "USB\nCommand\nArrived" -> "USB\nCommand\nArrived" [label="No" tailport=w headport=n]; "USB\nCommand\nArrived" -> "Has USB 3.0\nInterface Been\nSelected" [label = "Yes"]; "Has USB 3.0\nInterface Been\nSelected" -> end } The problem is when I render this in Graphviz the line created by "USB

In my Graphviz graph (written in DOT), I want each node to have a label, but in addition to that, I want some nodes to have a small caption denoting some other unique value for that node. For example, if this were for a history diagram, a node's label might be something like "Birth of George Washington" and the caption might read "See also: American Revolution." This is fairly flexible, so the caption doesn't necessarily need to be inside the node, but I do need some other way of putting text that clearly isn't part of the label (e.g. is a different size, possibly a different color) and is in

Here is a very simplified example of my Dot graph: strict digraph graphName { A->B B->A } This creates Instead I want a single edge shown between A and B but with a double arrow head. I know how to get the double arrowhead as a global option: strict digraph graphName { edge [dir="both"] A->B B->A } But that looks very ugly, and not all of my edges should be dual headed. If I do more processing of the graph and detect the double reference myself and replace the two edges with a single edge, it looks OK. But I'd rather not have to do this extra step strict digraph graphName { A->B [dir="both"] }

I'm building a epsilon NFA to recognize a regular expression using the canonical construction. I'm using subgraphs to group various parts of the regular expression. The * operator is giving me particular trouble since dot has decided to move the order of the nodes around. I've tried adding edge weights to force particular edges to be short to keep the order of the edges in line but that does not seem to be working. What I would like to do is force the nodes in a subgraph in to be placed in a particular order so that the output graph is recognizable as a particular type of (well known)

I'm using graphviz (dot) to generate the graph you can see below. The node in the lower left corner (red ellipse) causes annoyance as its edges cross several edges of the adjacent node. Is there a way to restrain node placement to a certain area? I'm not aware of any means by which to control the placement of individual nodes. It doesn't really make sense, because in order to do that you'd need to know what the final graph will look like, yet placing one node manually would then change how the rest of the graph is rendered. I solved this problem by changing the order in which my nodes are
