在Sankey图中显示总值 [英] Show total values in Sankey Diagram

问题描述

例如，小提琴的波纹管显示水果>地方。我想知道有多少水果喜欢到这些地方以及有多少水果有联系。例如：

 芒果（3）
苹果（2）
菠萝（1）
  

所有三个都与A地点相关联，所以地点A应该是：

 （7）地点A 
  

（ 1更多是因为葡萄）

更新：看起来像v42默认增加了重量。

解决方案

请看这个 jsfiddle

code

  data1 = [
 ['Apple' ，'Place A'，1]，
 ['Apple'，'Place A'，1]，
 ['Grape'，'Place A'，1]，
 ['Grape ， B'，2]，
 ['Pineapple'，'Place A'，1]，
 ['Strawberry'，'Place B'，4]，
 ['Mango'， 'Place A'，3] 
]; 
 
 var sourceTotals = {}; 
 
 for（var i = 0; i< data1.length; i ++）{
 var item = data1 [i]，
 key = item [0]; 
 if（sourceTotals.hasOwnProperty（key））{
 sourceTotals [key] + = item [2]; 
} 
 else {
 sourceTotals [key] = item [2]; 
} 
} 
 
 console.log（sourceTotals）; 
 
 var destTotals = {}; 
 
 for（var i = 0; i< data1.length; i ++）{
 var item = data1 [i]，
 key = item [1]; 
 if（destTotals.hasOwnProperty（key））{
 destTotals [key] + = item [2]; 
} 
 else {
 destTotals [key] = item [2]; 
} 
} 
 
 console.log（destTotals）; 
 $ b $ data1.forEach（function（d）{
d [0] = d [0] +（+ sourceTotals [d [0]] +）; 
d [1] =（+ destTotals [d [1]] +）+ d [1]; 
}）
  

Is it possible to show a total in sankey diagram?

For example, the fiddle bellow show Fruits > Place. I would like to know how many fruits are liked to the places and in places how many fruits are linked. So something like:

Mango (3)
Apple (2)
Pineapple (1)

All three are linked to Place A, so Place A should be:

(7) Place A

(1 more is because of Grape)

UPDATE: Looks like the v42 added weight by default.

解决方案

Take a look at this jsfiddle

code

data1 = [
              ['Apple', 'Place A', 1],
              ['Apple', 'Place A', 1],
              ['Grape', 'Place A', 1],
              ['Grape', 'Place B', 2],
              ['Pineapple', 'Place A', 1],
              ['Strawberry', 'Place B', 4],
              ['Mango', 'Place A', 3]
];

var sourceTotals = {};

for (var i = 0; i < data1.length; i++) {
    var item = data1[i],
        key = item[0];
    if (sourceTotals.hasOwnProperty(key)) {
        sourceTotals[key] += item[2];
    }
    else {
        sourceTotals[key] = item[2];
    }
}

console.log(sourceTotals);

var destTotals = {};

for (var i = 0; i < data1.length; i++) {
    var item = data1[i],
        key = item[1];
    if (destTotals.hasOwnProperty(key)) {
        destTotals[key] += item[2];
    }
    else {
        destTotals[key] = item[2];
    }
}

console.log(destTotals);

data1.forEach( function(d) {
    d[0] = d[0] + " (" + sourceTotals[d[0]] + ")";
    d[1] = "(" + destTotals[d[1]] + ") " + d[1];
})
