javascript - float 为什么线又回到左上角？

Question

这是我的代码:

var holder = $('#line-chart');

           if (holder.length) {
               $.plot(holder, [
                    { data: data[0].data, lines: { show: true }, label:"Service Level" },
                    { data: data[1].data, bars: { show: true }, yaxis: 2, label:"# Of Calls" } // set second series to use second axis
               ], {
                   yaxes: [{
                       min: 0, // options for first axis
                       tickFormatter: function (val, axis) {
                           return val + '%';
                       }
                   }, {
                       alignTicksWithAxis: 1, // options for second axis, put it on right
                       position: "right"
                   }],
                   xaxis: {
                       min: minVal.getTime(),
                       max: maxVal.getTime(),
                       mode: "time",
                       timeformat: timeFormat,
                       //twelveHourClock: true,
                       tickSize: [tickVal, modeChart],
                       //monthNames: ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec"],
                       tickLength: 0
                   },
                   grid: {
                       hoverable: true,
                       clickable: false,
                       borderWidth: 0
                   },
               });
           }

这是结果:

请注意，服务级别行(橙色行)是从Aug到左上角。你能帮我一下吗？

我从这次操作中获取了数据

 var data = $.map(result, function (arr, key) {
               return { label: key, data: arr };
           });

其中结果来自json请求，并打印我这样做的结果

var s = JSON.stringify(result);
           console.log(s)

这就是控制台显示的内容

Answer 1

该线返回到左上角，因为这就是您的数据的作用。

您的第一个服务级别是[1390608000000,50]。随后的服务级别第一个数字(x 坐标)不断增加......直到:

[1407283200000,0],[1390780800000,100],[1391040000000,100], ....

看到 - x 坐标已切换回(几乎)与开始时相同的位置，但 y 坐标为 100%。

所以你的代码没有问题——问题在于数据。
