我是角度 js 的新手。当我尝试执行以下代码时。它在控制台中显示一些错误。ReferenceError：图表未定义。我无法理解错误。所以任何人请帮助我。如果问题不正确，请更正问题

我的 HTML 代码：

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="utf-8" />
        <title>school</title>
        <link rel="stylesheet" href="style.css" type="text/css"/>
        <link rel="stylesheet" href="fonts/text-font/css/font_icon.css" type="text/css"/>
        <meta name="viewport" content="width=device-width; initial-scale=1.0" />
        <script type="text/javascript" src="js/jquery.min.js"></script>

        <script type="text/javascript" src="js/angular/angular-chart.min.js"></script><br />
        <script type="text/javascript" src="js/angular/angular.js"></script>

        <script type="text/javascript" src="js/script.js"></script>
    </head>
    <body ng-app="app">
        <div ng-controller="LineCtrl">
                <canvas id="line" class="chart chart-line" chart-data="data" chart-labels="labels" 
                chart-legend="true" chart-series="series" chart-click="onClick"></canvas> 

            </div>
    </body >
</html>

我的 angular.js ：

angular.module("app", ["chart.js"]) 
  // Optional configuration
  .config(['ChartJsProvider', function (ChartJsProvider) {
    // Configure all charts
    ChartJsProvider.setOptions({
      colours: ['#FF5252', '#FF8A80'],
      responsive: false
    });
    // Configure all line charts
    ChartJsProvider.setOptions('Line', {
      datasetFill: false
    });
  }])
  .controller("LineCtrl", ['$scope', '$timeout', function ($scope, $timeout) {

  $scope.labels = ["January", "February", "March", "April", "May", "June", "July"];
  $scope.series = ['Series A', 'Series B'];
  $scope.data = [
    [65, 59, 80, 81, 56, 55, 40],
    [28, 48, 40, 19, 86, 27, 90]
  ];
  $scope.onClick = function (points, evt) {
    console.log(points, evt);
  };

  // Simulate async data update
  $timeout(function () {
    $scope.data = [
      [28, 48, 40, 19, 86, 27, 90],
      [65, 59, 80, 81, 56, 55, 40]
    ];
  }, 3000);
}]);

您需要添加chart.js库的引用才能使您的图表正常工作。由于 angular-chart.js 内部使用库Chart对象chart.js。

我把我在评论中提到的更正，ng-app 和 ng-directives 丢失了。

索引.html

        </div>
    </body>

脚本.js

angular.module("app", ["chart.js"]) // here i couldn't understand about chart.js fil
  // Optional configuration
  .config(['ChartJsProvider', function (ChartJsProvider) {
    // Configure all charts
    ChartJsProvider.setOptions({
      colours: ['#FF5252', '#FF8A80'],
      responsive: false
    });
    // Configure all line charts
    ChartJsProvider.setOptions('Line', {
      datasetFill: false
    });
  }])
  .controller("LineCtrl", ['$scope', '$timeout', function ($scope, $timeout) {

  $scope.labels = ["January", "February", "March", "April", "May", "June", "July"];
  $scope.series = ['Series A', 'Series B'];
  $scope.data = [
    [65, 59, 80, 81, 56, 55, 40],
    [28, 48, 40, 19, 86, 27, 90]
  ];
  $scope.onClick = function (points, evt) {
    console.log(points, evt);
  };

  // Simulate async data update
  $timeout(function () {
    $scope.data = [
      [28, 48, 40, 19, 86, 27, 90],
      [65, 59, 80, 81, 56, 55, 40]
    ];
  }, 3000);
}]);

我为它做了一个jsbin。

这可能是 chart.min.js 和 angular-chart.min.js 文件的顺序问题。实际上angular-chart.min.js需要chart.min.js依赖。angular-chart.min.js检查chart.min.js，如果chart.min.js放在后面会产生错误。

在遵循 Angular Chart 官方文档（ http://jtblin.github.io/angular-chart.js/ ）之后，我遇到了类似的问题（同样的错误）。就我而言，唯一缺少的（并且没有在此处提及）是“index.html”中对“Chart,js”的引用。

<script src="bower_components/Chart.js/Chart.min.js"></script>

这对我有用：

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.11/angular.min.js"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/Chart.js/2.6.0/Chart.min.js"></script>

<script src="http://cdn.jsdelivr.net/angular.chartjs/latest/angular-chart.min.js"></script>
