绘制图表ajax动态URL从服务器端获取数据

As I see to the flot reference. they said,

正如我所看到的flot参考。他们说,

The plot function can also be used as a jQuery chainable property.

plot函数也可以用作jQuery可链接属性。

Is possible to define the flot chart to be like this?

可以将flot图表定义为这样吗?

var pid = '';
var kid = '';
var chartasset;

$(document).ready(function() {
 var optionchart = {
  series: {
   pie: {
    show: true,                
    label: {
     show:true,
     radius: 0.8,
     formatter: function (label, series) {                
      return '<div style="border:1px solid grey;font-size:8pt;text-align:center;padding:5px;color:white;">' + label + ' : ' + Math.round(series.percent) + '%</div>';
     },
     background: {
      opacity: 0.8,
      color: '#000'
     }
    }
   }
  }
 };

 chartasset = $('#chartasset').plot({
  "ajax" : {
   "url": "<?php echo site_url('Asset/chart_asset')?>?pid="+pid+"&kid="+kid,
   "type": "POST",
   "cache": false,
   "dataType": "json"
  }, optionchart}).data('plot');
});

I need to make the url dynamically change in another function, so I can use :

我需要让url在另一个函数中动态更改,所以我可以使用:

chartasset.ajax.url("<?php echo site_url('Asset/chart_asset')?>?pid="+pid+"&kid="+kid).load();

How can I use the flot chainable property to get the data, after I'm defining the flot? Sorry for my bad english

在我定义flot之后,如何使用flot chainable属性来获取数据?对不起,我的英语不好

No, you can not define the Flot chart like that. If you want to use AJAX, do it this way (result has to be in the right format):

不,你不能像那样定义Flot图表。如果你想使用AJAX,那就这样做(结果必须是正确的格式):

$.ajax({
    "url": "<?php echo site_url('Asset/chart_asset')?>?pid="+pid+"&kid="+kid,
    "type": "POST",
    "cache": false,
    "dataType": "json",
    success: function(result) {
        chartasset = $('#chartasset').plot(result, optionchart).data('plot');
    }
}
