Question

我看到了一个分层条形图的示例，并使其适用于我的数据集。

http://d3-example.herokuapp.com/examples/bar/bar-hierarchy.html

但是，我希望切换x轴和Y轴。基本上，我希望看到一个带有分层数据的垂直条形图。请帮助！

干杯，阿琼

Answer 1

在这里，我已经解决了你的问题码你会得到解决方案。

＆＃13;

var hello = angular.module("HelloApp", ["ngRoute", "Test.auth"]);

hello.run(function(UserInfo) {
  UserInfo.init();
});

hello.config(function($routeProvider) {
  $routeProvider
    .when("/login", {
      templateUrl: "/test/auth.html",
      controller: "AuthCtrl"
    })
    .when("/", {
      templateUrl: "/test/hello.html",
      controller: "HelloCtrl",
      resolve: {
        hello: function(Hello) {
          console.log("resolve.hello");
          return Hello.promise;
        }
      }
    })
    .otherwise({
      redirectTo: "/"
    });
});

hello.service("Hello", function($http) {
  this.promise = $http.get("/api/v1/utils/hello")
    .then(function(response) {
      console.log("Fetched '" + response.data + "'");
      return response.data;
    });
});

hello.controller("HelloCtrl", function($scope, hello) {
  $scope.hello = hello;
});

这不是很正确..但它已经到了一半..动画不像单杠一样好用，钻取完全不起作用..希望有人可以帮助添加它..

var m = [40, 50, 5, 70], // top right bottom left
w = 550 - m[1] - m[3], // width
h = 384 - m[0] - m[2], // height
y = d3.scale.linear().range([h,0]),
x = 70, // bar width
z = d3.scale.ordinal().range(["steelblue", "#aaa"]); // bar color

var hierarchy = d3.layout.partition()
    .value(function(d) { return d.size; });

var yAxis = d3.svg.axis()
    .scale(y)
