有没有办法在Google Charts的TreeMap中显示子标签 [英] Is there a way to display the children labels in Google Charts' TreeMap

问题描述

我正在尝试使用Google Charts创建一个TreeMap，它不仅显示父标签以及孩子的颜色分类，还显示孩子的标签。我基本上想要这个（保存可能的儿童颜色）：

I'm trying to create a TreeMap using Google Charts that not only shows the parent label along with the children's color breakdowns, but also the children's labels. I basically want this (save possible children coloration):

我还没有找到任何在线示例或问题，这可能吗？

I haven't found any online examples or questions on it, is this possible?

推荐答案

不确定你是否能完全像图片，

但是如果你想要显示父标签和子标签，

使用选项 - > maxDepth：2

not sure that you can get exactly like the picture,
but if you want to show both the parent and child labels,
use option --> maxDepth: 2

注意：不允许重复的子ID，

这里，对象表示法用于提供唯一的ID，

但仍然在多个节点上显示相同的名称

note: duplicate child id's are not allowed,
here, object notation is used to provide a unique id,
but still display the same name on multiple nodes

{v: 'Rick0', f: 'Rick'}
{v: 'Rick1', f: 'Rick'}

其中...

v： = value

f： = 格式化值

where...
v: = value
f: = formatted value

请参阅以下工作sni ppet ...

see following working snippet...

google.charts.load('current', {
  packages: ['treemap']
}).then(function () {
  var data = google.visualization.arrayToDataTable([
    ['Person', 'Fruit', 'Size', 'Color'],
    ['Global', null, 0, 0],
    ['Bananas', 'Global', 0, 0],
    [{v: 'Rick0', f: 'Rick'}, 'Bananas', 100, 0],
    [{v: 'Anne0', f: 'Anne'}, 'Bananas', 40, 0],
    [{v: 'Peter0', f: 'Peter'}, 'Bananas', 5, 0],
    ['Apples', 'Global', 0, 0],
    [{v: 'Anne1', f: 'Anne'}, 'Apples', 20, 2],
    [{v: 'Peter1', f: 'Peter'}, 'Apples', 20, 2],
    [{v: 'Rick1', f: 'Rick'}, 'Apples', 15, 2],
    ['Oranges', 'Global', 0, 0],
    [{v: 'Rick2', f: 'Rick'}, 'Oranges', 20, 1],
    [{v: 'Peter2', f: 'Peter'}, 'Oranges', 20, 1],
    [{v: 'Anne2', f: 'Anne'}, 'Oranges', 10, 1],
    ['Susanne', 'Global', 10, null]
  ]);

  tree = new google.visualization.TreeMap(document.getElementById('chart_div'));
  tree.draw(data, {
    maxDepth: 2,
    minColor: 'yellow',
    midColor: 'orange',
    maxColor: 'red',
    noColor: 'lime',
  });
});
