最近刚开始做图形操作,纠结了一上午,highchat 动态绑定数据这块一直不知道怎么绑定,后来多次尝试,发现
1.x轴的数据是个数组格式,我从后台传到前台的时候,js中用数组进行处理数据,然后赋值到chat就不会报错,
2.y轴的数据和x轴数据还不一样,通过数组处理后发现还是无法显示。后来我在后台将数据添加了中括号[]括起来后,传到前台,然后前台在用eval()处理后就能够显示了
3.eval具有计算的功能,刚开始x轴的时候我用了eval对时间进行操作发现时间都是相减了,格式为:2017-07-27,格式居然为1998这样的。
下面是我的后台和前台的程序逻辑:
1.后台MVC控制器
1 public ActionResult Index() 2 { 3 return View(); 4 } 5 public ActionResult GetAllReport() 6 { 7 var result = new { key = "2017-01-02,2017-01-02,2017-01-02,2017-01-02,2017-01-02,2017-01-02,2017-01-02,2017-01-02,2017-01-02,2017-01-02,2017-01-02,2017-01-02", value1 = "[9,23,24,54,67,1,23,45,23,444,55,89]", value2 = "[99,89,78,67,76,75,49,47,21,32,33,55]" }; 8 return Json(result); 9 }
2.前台:
@{ Layout = null; } <!DOCTYPE html> <html> <head> <meta name="viewport" content="width=device-width" /> <title>Index</title> <script src="~/charts/highcharts/exporting.js"></script> <script src="~/charts/highcharts/highcharts.js"></script> <script src="~/charts/highcharts/highcharts_jquery-1.8.3.min.js"></script> </head> <body> <div id="container"> </div> </body> </html> <script type="text/javascript"> $(function () { $.ajax({ url: ‘/Home/GetAllReport‘, dataType: "json", type: "POST", data: null, success: function (data) { alert(data.key); Chart(data.key, data.value1, data.value2); }, error: function (jqXHR, textStatus, errorThrown) { alert("出错"); } }); }); function Chart(key, value1, value2) { var mycars = new Array(); var myvalue1 = new Array(); var myvalue2 = new Array(); var _tkey = key.split(‘,‘); for (var i = 0; i < _tkey.length; i++) { mycars[i] = _tkey[i]; } var _tvalue1 = value1.split(‘,‘); for (var i = 0; i < _tvalue1.length; i++) { myvalue1[i] = _tvalue1[i]; } var _tvalue2 = value2.split(‘,‘); for (var i = 0; i < _tvalue2.length; i++) { myvalue2[i] = _tvalue2[i]; } var chart = new Highcharts.Chart(‘container‘, { title: { text: ‘不同城市的月平均气温‘, x: -20 }, subtitle: { text: ‘数据来源: WorldClimate.com‘, x: -20 }, xAxis: { categories: mycars }, yAxis: { title: { text: ‘温度 (°C)‘ }, plotLines: [{ value: 0, width: 1, color: ‘#808080‘ }] }, tooltip: { valueSuffix: ‘°C‘ }, legend: { layout: ‘vertical‘, align: ‘right‘, verticalAlign: ‘middle‘, borderWidth: 0 }, series: [{ name: ‘东京‘, data: eval(value1) }, { name: ‘纽约‘, data: eval(value2) }] }); } </script>
另外呢还有一些 小处理
1. 2条折线重复的时候,鼠标放上去需要都显示数据
tooltip: { shared: true }
2. 去除highchat.com 网址
credits: { enabled: false }
3. 刷新数据的时候 需要将上次的折线图清除
function clearTable() { var series = chart.series; if (series.length > 0) { series[0].remove(false); } }
