Question

我很难从PHP脚本中获取数据并将其设置为Gauge图。我正确得到了json结果，只是不知道如何将它设置为正确的Highchart规范变量（gaugeOptions）。

我想在PHP中输入＃container-C_2 返回的值，因此配置min，max并在gauge图表上设置值。强文我想在我需要调用的 $。getJSON（）主体中 $（'＃container-C_2'）。highcharts（有一些参数，但不知道怎么做..

有人可以帮助我吗？

非常感谢。

PHP

    $result = array();
    $result['name'][0] = 'A';

    //--some values    
    $result['min'][] = 10;
    $result['max'][] = 50;
    $result['val'][]  = 20;

    $json = array();
    array_push($json,$result);

print json_encode($json);

Answer 1

//This seems not to have any effect
gaugeOptions.yAxis.min = json[0]['min'];
gaugeOptions.yAxis.max = json[0]['max'];
gaugeOptions.yAxis.title.text = 'JUST SOME TEXT...';

gaugeOptions.series[0] = {};
//gaugeOptions.series[0].name = json[0]['name'][0];
gaugeOptions.series[0].name = json[0]['name'];
gaugeOptions.series[0].data = json[0]['val'];

而不是这个

tableData

Highcharts规范，在$ .getJSON调用后设置检索到的数据
