我正在尝试使用ZingChart创建实时时间序列图.但我希望它是累积的,其中所有点在数据追加时累积.所以我在每个ajax轮询中使用"appendseriesvalues"来附加数据,并将数据作为JSON对象传递给(key,value)对.

我的代码如下:

     var chartData = {
        "show-progress":false,
        "gui":{
            "behaviors":[
                {
                    "id":"ZoomIn",

    "type":"line",
  //  "utc":true, /* Force UTC time. */
   // "timezone": -5,
    "plotarea": {
      "adjust-layout":true /* For automatic margin adjustment. */
    },
    "scale-x":{
        "values": [],
      "label":{ /* Add a scale title with a label object. */
        "text":"Above is an example of a time-series scale",
      },
      "min-value":1420070400000, /* Unix timestamp for Jan 1, 2015. */
      "step":"second",
      "transform":{ /* Converts …
