Question

我想将mysql结果加载到highcharts＆＃39;使用json的线图。在下面的代码中，xAxix是手动输入的。我如何从mysql数据库中动态提供它？你也会找到php代码和html代码。感谢

＆＃13;

$ g++ -std=c++0x -O0 -fno-implement-inlines -g t.cpp

$ ./a.out
Base Stack: 0x7ffff2826c8c
Sizeof(t): 2048
usePassByRef: stack: 0x7ffff282645c size on stack: 2096
usePassByValue: stack: 0x7ffff2825c1c size on stack: 2112
usePassPointer: stack: 0x7ffff2825bdc size on stack: 64

您只需{J}代码echo即可获得图表设置的xAxis属性：

subtitle: {
    text: '',
    x: -20
},
xAxis: <?php echo json_encode($result, JSON_NUMERIC_CHECK); ?>,
yAxis: ...

或者，如果您使用AJAX请求检索数据，请在初始化图表之前执行请求，并以相同的方式使用返回数据。

如何动态提供高图线图的xAxis
