Plotly 节点红色

Question

我正在尝试使用模板节点从节点红色生成一个简单的 plotly 图表。 如果 x 和 y 是 static 值，Plotly 正确绘图，但是当我使用有效负载将数据输入 plot 变量时，它不会打印。 我已检查并且数据已正确传输。 请看代码。 \

Mustache 节点中的代码

下面的代码可以正常工作并正确创建图表。

<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>

下面的代码不起作用，而是 plotly 只显示坐标。

<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：调试 window 中查看的数据如下

`

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],

我在做什么错，谢谢。

您需要查看如何将日期转换为区域设置字符串...仅将它们嵌入到 javascript 呈现的代码中不会生成有效的 Javascript 代码。 使用您在评论中添加的这段代码：

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
};

该属性x应该是日期字符串的数组...

    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... ],

...或代表纪元毫秒的数字数组...

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

您是否使用数据库查询来获取这些 x 值？ If so, I would use some sql function in the query to output the internal unix time (sec.) * 1000 to get millis. 否则，您必须在template节点之前的 javascript 代码中对数组中的每个元素使用Date.parse("Tue Oct 08 2019 12:47:58 GMT-0400 (Eastern Daylight Time)")进行转换。 ..非常低效。
