Question

我正在尝试使用flot.js绘制一些电流f。问题是我无法在代码中使用flot.js。我正在使用的jQuery版本是3.4.0。 Flot版本是0.8.3

该代码可以在不包含flot库的情况下正常运行。

我的index.php


    <html>
    <head>
        <title>Jupiter</title>
        <link rel="icon" href="./pics/jupiter.png">

    <body>

Main content here
<div id="RFD_curent_1"></div>
</body>
<script src='./js/index.js'></script>
</html>

我的index.js


    function initialize_currents(){
            var time=(new Date).getTime();
            for(var i=0;i<14400;i++){
                //data1.push([time+i-14400000,32]);
                data1.push([]);
            }
            for(var i=0;i<14400;i++){
                //data2.push([time+i-14400000,25]);
                data2.push([]);
            }
            //data.push([time,0]);
            var dataset = [{label: "0xbb36",data: data1},{label:"0xc563",data:data2}];
            $.plot($("#RFD_curent_1"), dataset, options);
        }
    $(document).ready(function() {
            initialize_currents();
    }

我在Chrome控制台中收到以下警告和错误消息

Answer 1

所以我知道问题很简单，您用逗号（，）演示了浮点数，应该是点（。）

//data2.push([time+i-14400000.25]);

Answer 2

Flot期望其数据集中包含两个元素的数组（x值，y值）。您给它一个包含许多空数组的数组。您可能应该使用

之类的东西

data2.push([i, i]);

作为测试数据。

一起使用flot和bootstrap
