D3ネストとオブジェクトトラバーサル

Question

私は以下の共有としてjsonを持っており、私は視覚化の前にデータをネストしようとしています。私はgovとnon-govの下でどのように各ベンダーが高低プロジェクトのために配布されているかを確認したい。[{v1: {Gov: {high:3, low:2}, {Non-Gov: {high:12, low:1}}}, {v2:{Gov: {high:3, low:2}, {Non-Gov: {high:12, low:1}}}, ...]

私はデータをネストできますが、それぞれのカウントを得ることはできません。どんな指導も高く評価されます。疑問文があいまいな場合はお詫び申し上げます。

1. ロールアップロールアップ

   n = d3.nest().key(function(d){return d.vendor;}) 
        .key(function(d){return d.ptype;}) 
        .key(function(d){return d.critical;}) 
        .rollup(function(leaf){ 
        return[ 
        {key:'GH', value:leaf[0].values.length} 
        ,{key:'GL',value:leaf[1].values.length} 
        ]}) 
        .entries(j); 
   

Answer 1

は、私はこのようにそれを行うことができ

var nested_data = d3.nest() 
.key(function(d) { return d.vendor; }).sortKeys(d3.ascending) 
.key(function(d) { return d.ptype; }).sortKeys(function(d) { return d;}) 
.key(function(d) { return d.critical; }).sortKeys(function(d) { return d;}) 
.rollup(function(leaves) { return leaves.length; }) 
.entries(j); 

ありがとう：yは、unoptimsed）バージョンは、それが行くような値をつかみます！

Answer 2

と

n = d3.nest().key(function(d){return d.vendor;}) 
    .key(function(d){return d.ptype;}) 
    .key(function(d){return d.critical;}) 
    .entries(j); 

のない私はD3を知っているが、次のようにデータを変換することができバニラJSを使用していません：

var input = [ { "vendor": "V1", "ptype": "Gov", "critical": "high" }, { "vendor": "V2", "ptype": "Gov", "critical": "low" }, { "vendor": "V3", "ptype": "Gov", "critical": "high" }, { "vendor": "V4", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V5", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V6", "ptype": "Gov", "critical": "high" }, { "vendor": "V7", "ptype": "Gov", "critical": "high" }, { "vendor": "V8", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V9", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V10", "ptype": "Gov", "critical": "high" }, { "vendor": "V1", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V2", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V3", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V4", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V5", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V6", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V7", "ptype": "Gov", "critical": "low" }, { "vendor": "V8", "ptype": "Gov", "critical": "high" }, { "vendor": "V9", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V10", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V1", "ptype": "Gov", "critical": "high" }, { "vendor": "V2", "ptype": "Gov", "critical": "low" }, { "vendor": "V3", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V4", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V5", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V6", "ptype": "Gov", "critical": "high" }, { "vendor": "V7", "ptype": "Gov", "critical": "high" }, { "vendor": "V8", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V9", "ptype": "Gov", "critical": "high" }, { "vendor": "V10", "ptype": "Gov", "critical": "low" } ]; 
 

 
var working = input.reduce(function(p, c) { 
 
    var v = p[c.vendor]; 
 
    if (!v) v = p[c.vendor] = {Gov: {high: 0, low: 0}, "Non-Gov": {high: 0, low: 0}}; 
 
    v[c.ptype][c.critical]++; 
 
    return p; 
 
    }, {}); 
 

 
var output = Object.keys(working).map(function(v) { 
 
    var o = {}; 
 
    o[v] = working[v]; 
 
    return o; 
 
    }); 
 

 
console.log(output);

それとも、ES6の構文を使用することができます場合は、.map()一部たくさん短くすることができます。

var input = [ { "vendor": "V1", "ptype": "Gov", "critical": "high" }, { "vendor": "V2", "ptype": "Gov", "critical": "low" }, { "vendor": "V3", "ptype": "Gov", "critical": "high" }, { "vendor": "V4", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V5", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V6", "ptype": "Gov", "critical": "high" }, { "vendor": "V7", "ptype": "Gov", "critical": "high" }, { "vendor": "V8", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V9", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V10", "ptype": "Gov", "critical": "high" }, { "vendor": "V1", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V2", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V3", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V4", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V5", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V6", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V7", "ptype": "Gov", "critical": "low" }, { "vendor": "V8", "ptype": "Gov", "critical": "high" }, { "vendor": "V9", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V10", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V1", "ptype": "Gov", "critical": "high" }, { "vendor": "V2", "ptype": "Gov", "critical": "low" }, { "vendor": "V3", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V4", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V5", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V6", "ptype": "Gov", "critical": "high" }, { "vendor": "V7", "ptype": "Gov", "critical": "high" }, { "vendor": "V8", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V9", "ptype": "Gov", "critical": "high" }, { "vendor": "V10", "ptype": "Gov", "critical": "low" } ]; 
 

 
var working = input.reduce((p, c) => { 
 
    var v = p[c.vendor]; 
 
    if (!v) v = p[c.vendor] = {Gov: {high: 0, low: 0}, "Non-Gov": {high: 0, low: 0}}; 
 
    v[c.ptype][c.critical]++; 
 
    return p; 
 
    }, {}); 
 

 
var output = Object.keys(working).map(v => ({ [v]: working[v] })); 
 

 
console.log(output);

EDIT：それは多分と私に起こりました可能なptypeとcriticalの値をハードコードしたくないので、次のようにします（ugl ..

var input = [ { "vendor": "V1", "ptype": "Gov", "critical": "high" }, { "vendor": "V2", "ptype": "Gov", "critical": "low" }, { "vendor": "V3", "ptype": "Gov", "critical": "high" }, { "vendor": "V4", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V5", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V6", "ptype": "Gov", "critical": "high" }, { "vendor": "V7", "ptype": "Gov", "critical": "high" }, { "vendor": "V8", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V9", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V10", "ptype": "Gov", "critical": "high" }, { "vendor": "V1", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V2", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V3", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V4", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V5", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V6", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V7", "ptype": "Gov", "critical": "low" }, { "vendor": "V8", "ptype": "Gov", "critical": "high" }, { "vendor": "V9", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V10", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V1", "ptype": "Gov", "critical": "high" }, { "vendor": "V2", "ptype": "Gov", "critical": "low" }, { "vendor": "V3", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V4", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V5", "ptype": "Non-Gov", "critical": "high" }, { "vendor": "V6", "ptype": "Gov", "critical": "high" }, { "vendor": "V7", "ptype": "Gov", "critical": "high" }, { "vendor": "V8", "ptype": "Non-Gov", "critical": "low" }, { "vendor": "V9", "ptype": "Gov", "critical": "high" }, { "vendor": "V10", "ptype": "Gov", "critical": "low" } ];

    if (!v[c.ptype][c.critical]) v[c.ptype][c.critical] = 1; 
 
    else v[c.ptype][c.critical]++; 
 

 
    p.ptypes[c.ptype] = true; 
 
    p.criticals[c.critical] = true; 
 

 
    return p; 
 
    }, {vendors:{}, ptypes:{}, criticals:{}}); 
 

 
var output = Object.keys(working.vendors).map(v => { 
 
    var c = working.vendors[v]; 
 
    Object.keys(working.ptypes).forEach(p => {
