我正在尝试在角材料网格内获取响应式 nvd3 图表。在我调整窗口大小后它似乎工作正常，但在初始加载时没有达到正确的大小。

我的方法是将 nvd3 指令包装在“resize”指令中。然后我可以观察父元素并在窗口调整大小时更新图表的高度和宽度。我遇到的问题是加载父 div 的高度和宽度属性似乎为 0。我尝试使用 $timeout 来应用范围，但这似乎也不起作用。

angular.module('MyApp', ['ngMaterial', 'ngMessages', 'nvd3'])
  .controller('AppCtrl', function($scope) {
    $scope.options = {
      chart: {
        type: 'discreteBarChart',
        height: 450,
        margin: {
          top: 20,
          right: 20,
          bottom: 50,
          left: 55
        },
        x: function(d) {
          return d.label;
        },
        y: function(d) {
          return d.value + (1e-10);
        },
        showValues: true,
        valueFormat: function(d) {
          return d3.format(',.4f')(d);
        },
        duration: 500,
        xAxis: {
          axisLabel: 'X Axis'
        },
        yAxis: {
          axisLabel: 'Y Axis',
          axisLabelDistance: -10
        }
      }
    };

    $scope.data = [{
      key: "Cumulative Return",
      values: [{
        "label": "A",
        "value": -29.765957771107

  }).directive('resize', function($window, $timeout) {
    var linker = function(scope, element, attrs) {
      var w = angular.element($window);
      
      w.bind('resize', function() {
        scope.$apply();
      })
      
      $timeout(function(){
        updateHeight();
        updateWidth();
        scope.$apply();
      })

      scope.$watch(function() {

请查看此代码笔。

提前致谢

更新：我使用 Angular nvd3s api.updateWithOptions(options) 为我的应用找到了解决方案。仍然无法在代码笔中工作。可能是代码笔的版本差异将很快附上最终解决方案。

我对 angular-nvd3 和 angular-material 有同样的问题。我无法解释为什么会发生这种情况，并且自 2016 年 6 月以来它已经被报告为错误（请参阅https://github.com/krispo/angular-nvd3/issues/454）。

但是，我能够用一个简单的方法来修复它

angular.element(document).ready(function () {})

围绕 $scope.data 阻塞。

这个例子对我有用：

控制器

angular.module('app')

.controller('pieChartCtrl', function($scope){

    $scope.options = {
        chart: {
            type: 'pieChart',
            height: 500,
            x: function(d){return d.key;},
            y: function(d){return d.y;},
            showLabels: true,
            duration: 500,
            labelThreshold: 0.01,
            labelSunbeamLayout: true,
            legend: {
                margin: {
                    top: 5,
                    right: 35,
                    bottom: 5,
                    left: 0
                }
            }
        }
    };

    angular.element(document).ready(function () {
        $scope.data = [
            {
                key: "One",
                y: 5
            },
            {
                key: "Two",
                y: 2
            },
            {
                key: "Three",
                y: 9
            },
            {
                key: "Four",
                y: 7
            },
            {
                key: "Five",
                y: 4
            },
            {
                key: "Six",
                y: 3
            },
            {
                key: "Seven",
                y: .5
            }
           ];
    });    
})

看法

  <div ng-controller="pieChartCtrl">
      <nvd3 options="options" data="data"></nvd3>
   </div>
