结果是来自我的数据库的JSON格式是这样的（使用文档中的结构）
var yields = [{yield: 27.00, variety: "Manchuria", year: 1931, site: "University Farm"},
{yield: 48.87, variety: "Manchuria", year: 1931, site: "Waseca"},
{yield: 27.43, variety: "Manchuria", year: 1931, site: "Morris"}, ...]
所以我可以轻松地使用d3.nest()函数将其转换为
[{key: 1931, values: [
{key: "Manchuria", values: [
{yield: 27.00, variety: "Manchuria", year: 1931, site: "University Farm"},
{yield: 48.87, variety: "Manchuria", year: 1931, site: "Waseca"},
{yield: 27.43, variety: "Manchuria", year: 1931, site: "Morris"}, ...]},
{key: "Glabron", values: [
{yield: 43.07, variety: "Glabron", year: 1931, site: "University Farm"},
{yield: 55.20, variety: "Glabron", year: 1931, site: "Waseca"}, ...]}, ...]},
{key: 1932, values: ...}]
我的问题是，我可以使用此nest格式绘制树吗？例如，像this
我还没有找到根据nest()的结果创建树木的例子。
如果那里有任何我非常高兴的话。或者，也许从原始children创建flare＆＃39; JSON几乎是一样的。
感谢。
答案 0 :(得分：0)
如果您看到他们的数据，即他们的flare.json具有结构，可以通过使用d3.nest（）函数获得。 他们的flare.json的数据是

如果你观察这个json结构，我们可以使用d3.nest（）函数得到它。 我想你可能会要求澄清。希望这可以解决。

假设我们分配的数据就像我们使用d3.nest（）函数得到的那样，现在我将这些数据变成名称，子格式----观察下面的代码
var str = JSON.stringify(myData); /* Here converting object into string*/
str=str.replace(/"key":/gi, '"name":'); /* Here replacing key with name, which we want to see in the object */
str=str.replace(/"values":/gi, '"children":'); /* Here replacing values with children */
var res = JSON.parse(str); /* Here converting string into object back*/
希望这是你想要的。
