javascript - Chart.js - 在哪里放置全局图表配置？

Question

我正在尝试使用以下代码设置 Chart.js 折线图。我在哪里放置 Chart.defaults.global = {} 或 Chart.defaults.global.responsive = true; 代码？

Chart.js 文档可以在这里找到:http://www.chartjs.org/docs/

<!-- Chart.js -->
<script src="http://cdnjs.cloudflare.com/ajax/libs/Chart.js/0.2.0/Chart.min.js"></script>
<script>
    var ctx = document.getElementById("myChart").getContext("2d");
    var data = {
       labels: ["Week 1", "Week 2", "Week 3", "Week 4", "Week 5", "Week 6", "Week 7"],
       datasets: [
           {
               label: "My Second dataset",
               fillColor: "rgba(151,187,205,0.2)",
               strokeColor: "rgba(151,187,205,1)",
               pointColor: "rgba(151,187,205,1)",
               pointStrokeColor: "#fff",
               pointHighlightFill: "#fff",
               pointHighlightStroke: "rgba(151,187,205,1)",
               data: [86, 74, 68, 49, 42]
           }
       ]
   };

   var options = {
       ...
   };

   var myLineChart = new Chart(ctx).Line(data, options);
</script>

有两种方法可以满足您的需求。这样

var myLineChart = new Chart(ctx).Line(data, options);
var options = Chart.defaults.global = {
    responsive: true,
    maintainAspectRatio: true  
};

或者，这样

var myLineChart = new Chart(ctx).Line(data, {
    responsive: true,
    maintainAspectRatio: true
});

但是，要使其具有响应性，您必须添加一些额外的 CSS

canvas{
    width: 100% !important;
    height: auto !important;
}

所以不需要内联 CSS

根据下面@JustinXL 的评论和最新版本的 Chart.js，不需要额外的 CSS，所以请检查更新版本。
