如果要使用从data.json返回的JSON，则需要在回调函数中执行以下操作：
$.getJSON("data.json", function (json) { // will generate array with ['Monday', 'Tuesday', 'Wednesday'] var labels = json.map(function(item) { return item.timestamp; }); var data = { labels: labels, datasets: [ { label: "My First dataset", fillColor: "rgba(220,220,220,0.5)", strokeColor: "rgba(220,220,220,0.8)", highlightFill: "rgba(220,220,220,0.75)", highlightStroke: "rgba(220,220,220,1)", data: [65, 59, 80, 81, 56, 55, 40] }, { label: "My Second dataset", fillColor: "rgba(151,187,205,0.5)", strokeColor: "rgba(151,187,205,0.8)", highlightFill: "rgba(151,187,205,0.75)", highlightStroke: "rgba(151,187,205,1)", data: [28, 48, 40, 19, 86, 27, 90] } ] }; var ctx = document.getElementById("myChart").getContext("2d"); ctx.canvas.width = 1000; ctx.canvas.height = 800; var myChart = new Chart(ctx).Bar(data);});如果您将它与Angular一起使用，我建议您使用angular
chart.js版本，请参见：http

然后，您已经有了一个可以使用的角度指令！
