Plotly 節點紅色

Question

我正在嘗試使用模板節點從節點紅色生成一個簡單的 plotly 圖表。 如果 x 和 y 是 static 值，Plotly 正確繪圖，但是當我使用有效負載將數據輸入 plot 變量時，它不會打印。 我已檢查並且數據已正確傳輸。 請看代碼。 \

Mustache 節點中的代碼

下面的代碼可以正常工作並正確創建圖表。

<head>
  <!-- Plotly.js -->
  <script src="https://cdn.plot.ly/plotly-latest.min.js"></script>
</head>

<body>

  <div id="myDiv"><!-- Plotly chart will be drawn inside this DIV --></div>
  <script>

var trace1 = {
  x:[1,2,3],//[{{payload.Temperature}}],
  y:[1,2,3],//[{{payload.Temperature}}],
  //mode: 'lines',
  connectgaps: true
};

var data = [trace1];

var layout = {
  title: 'Connect the Gaps Between Data',
  showlegend: true
};

Plotly.newPlot('myDiv', data, layout, {showSendToCloud: true});

</script>
</body>

下面的代碼不起作用，而是 plotly 只顯示坐標。

<head>
  <!-- Plotly.js -->
  <script src="https://cdn.plot.ly/plotly-latest.min.js"></script>
</head>

<body>

  <div id="myDiv"><!-- Plotly chart will be drawn inside this DIV --></div>
  <script>

var trace1 = {
  x:[{{payload.time}}],
  y:[{{payload.Temperature}}],
  mode: 'lines',
  connectgaps: true
};

var data = [trace1];

var layout = {
  title: 'Connect the Gaps Between Data',
  showlegend: true
};

Plotly.newPlot('myDiv', data, layout, {showSendToCloud: true});

</script>
</body>

注意：調試 window 中查看的數據如下

`

x:[Tue Oct 08 2019 12:47:58 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:47:28 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:47:21 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:46:30 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:42:58 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:41:17 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:37:58 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:37:28 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:37:23 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:36:17 GMT-0400 (Eastern Daylight Time)],
  y:[26.76,27.76,27.51,27.11,26.76,27.15,26.75,27.9,27.77,27.23],

我在做什么錯，謝謝。

您需要查看如何將日期轉換為區域設置字符串...僅將它們嵌入到 javascript 呈現的代碼中不會生成有效的 Javascript 代碼。 使用您在評論中添加的這段代碼：

var trace1 = {
    x: [Tue Oct 08 2019 12:47:58 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:47:28 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:47:21 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:46:30 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:42:58 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:41:17 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:37:58 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:37:28 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:37:23 GMT-0400 (Eastern Daylight Time),Tue Oct 08 2019 12:36:17 GMT-0400 (Eastern Daylight Time)],
    y: [26.76,27.76,27.51,27.11,26.76,27.15,26.75,27.9,27.77,27.23],
    mode: 'lines',
    connectgaps: true
};

該屬性x應該是日期字符串的數組...

    x: ["Tue Oct 08 2019 12:47:58 GMT-0400 (Eastern Daylight Time)", "Tue Oct 08 2019 12:47:28 GMT-0400 (Eastern Daylight Time)", ...etc... ],

...或代表紀元毫秒的數字數組...

    x: [1570553278000, 1570553248000, ...etc... ],

您是否使用數據庫查詢來獲取這些 x 值？ If so, I would use some sql function in the query to output the internal unix time (sec.) * 1000 to get millis. 否則，您必須在template節點之前的 javascript 代碼中對數組中的每個元素使用Date.parse("Tue Oct 08 2019 12:47:58 GMT-0400 (Eastern Daylight Time)")進行轉換。 ..非常低效。
