Question

我无法让Flot格式化时间序列日期。我的xaxis看起来像这样：

 16:63 20:26 00:36 08:36 12:36 16:36 20:36

这是怎么发生的？那是时候吗？

我接受“％y /％m /％d”格式的数据。

我使用的是0.8.0-alpha和angular2。

以下是我的代码：

       let dataset = [
        {
            label: "Mean",
            data: data_ts["mean_1"],
            //color: "#FF0000",
            points: { fillColor: "#FF0000", show: true },
            lines: { show: true }
        },
        {
            label: "Var",
            data: data_ts["var_1"],
            //color: "#FF0000",
            points: { fillColor: "#FF0000", show: true },
            lines: { show: true }
        }
    ];

    let options = {
        xaxis: { mode: "time" },
        minTickSize: [1, "month"],
        timeformat: "%y/%m/%d"
    };
    this.plot = $.plot($("#placeholder_ts"),dataset,options);
    this.plot.setupGrid();
    this.plot.draw();

以下是带时间戳的数据：

您是不是应该将timeformat放在xaxis内，以及minTickSize：

let options = {
    xaxis: { 
       mode: "time", 
       timeformat: "%y/%m/%d",
       minTickSize: [1, "month"]
    }        
};

Flot与时间轴行为不当
