我正在尝试使用模板节点从节点红色生成一个简单的图表。如果x和y是静态值，则正确地绘制图表，但是由于使用有效负载将数据获取到绘制变量中，因此无法打印。我已检查并正确传输了数据。请查看代码。 \
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，而是只显示坐标。
<head>
<!-- Plotly.js -->
<script src="https://cdn.plot.ly/plotly-latest.min.js"></script>

<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：在调试窗口中查看的数据为ans后继]

我做错了，谢谢。
[您需要查看日期如何转换为语言环境字符串...仅将日期嵌入到javascript呈现的代码中并不会生成有效的Javascript代码。将此代码段放入注释中：
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应该是任一日期的数组字符串 ...
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numbers的数组，表示epoch millis ...
x: [1570553278000, 1570553248000, ...etc... ],
您是否使用数据库查询来获取这x个值？如果是这样，我将在查询中使用一些sql函数来输出内部unix时间（秒）* 1000以获取毫秒。否则，您将必须在JavaScript代码之前 template节点中进行转换，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)") ...效率很低。
