如何在高线图中输入具有x轴和y轴值的系列数据? [英] How to feed series data that has x axis and y axis values in line highcharts?

问题描述

我必须在折线图中显示实验的一些结果.我让它适用于静态数据，但我想使其动态化.

I have to show some results of an experiment in a line chart. I got it working for static data, but I want to make it dynamic.

所以我得到了:

我有一个折线图:

       var options = {
            chart: {
                renderTo: 'container',
                        type: 'line',
                            },
                    series: [{}]
        }

我想要这样的东西:我正在努力制作这些数据:

I am struggling to make those data:

            data: [
            [0, 29.9], 
            [1, 71.5], 
            [3, 106.4]
        ]

在php端

并将其发送给jquery，并提供给我的折线图. 我知道JSON编码，但是首先应该如何在php中创建数组? 以及如何编码并将其提供给jquery并提供折线图?

in php side and send it jquery, and feed to my line chart. I am aware of JSON encoding, but how should I create and array in php in first place? And how should I encode it and give it to jquery and feed my line chart?

到目前为止，此方法可以处理静态数据:

This is working so far with static data:

             var arr = [[0, 15], [10, 50], [20, 56.5], [30, 46.5], [40, 22.1],
                            [50, 2.5], [60, 27.7], [70, 55.7], [80, 76.5]];
                options.series[0].name = 'Occlusion';
                options.series[0].data = arr;
    var l = new Highcharts.Chart(options);
    });

但是我希望arr来自php.

But I want arr to come from php.

先谢谢了.

推荐答案

如果要创建这种格式，则需要首先对其进行重组.考虑以下示例:

If you want to create such format, you need to restructure them first. Consider this example:

<?php

// lets say you have a raw data like this
$php_values = array(
    array(0, 15),
    array(10, 50),
    array(20, 56.5),
    array(30, 46.5),
    array(40, 22.1),
    array(50, 2.5),
    array(60, 27.7),
    array(70, 55.7),
    array(80, 76.5),
);

$temp = array();
// format each array
foreach($php_values as $key => $value) {
    $temp[] = '['.implode(',', $value).']';
}
// then format the whole array
$formatted_values = '['.implode(',', $temp).']';

?>
<script type="text/javascript">

    var values = <?php echo $formatted_values; ?>;
    console.log(values);

</script>

示例输出

正如@SebastianBochan指出的那样， $formatted_values = json_encode($php_array) 的工作方式相同(可能是最好，最干净的方式)

as @SebastianBochan pointed out, $formatted_values = json_encode($php_array) works the same way (probably the best and cleanest way)
