Highchart：无法从JSON填充数据

Question

我正在尝试学习高图，但是当我尝试从JSON填充数据时，它无法正常工作。但我硬编码它工作正常的数据。所以，我认为在调用JSON时我犯了一些错误。

我的JSON看起来像： -

[{
"data": ["11-Aug 12:03", "11-Aug 12:45", "11-Aug 13:13", "11-Aug 13:53", "11-Aug 14:03", "11-Aug 14:33", "11-Aug 14:54", "11-Aug 15:17", "11-Aug 15:49", "11-Aug 16:07", "11-Aug 17:00", "11-Aug 17:33"]
}, {
 "data": [23987, 24784, 25899, 255, 25897, 25668, 24114, 23899, 224987, 25111, 25899, 23]
}, {
"data": [12.4, 4.56, 3.8, 1.2, 11, 12.3, 5.67, 7.65, 34.5, 12.78, 10.5, 2.8]
}]

添加整个代码： -

$(function () {
$('#container').highcharts({
    chart: {
        zoomType: 'xy'
    },
    title: {
        text: 'Job Status'
    },

    xAxis: [{
        categories: [],
        crosshair: true
    }],
    yAxis: [{ // Primary yAxis
        labels: {

            style: {
                color: Highcharts.getOptions().colors[2]
            }
        },
        title: {
            text: 'Transaction Count',
            style: {
                color: Highcharts.getOptions().colors[2]
            }
        },
        opposite: true

    }, { // Secondary yAxis
        gridLineWidth: 0,
        title: {
            text: 'Time',
            style: {
                color: Highcharts.getOptions().colors[0]
            }
        },
        labels: {
            format: '{value} min',
            style: {
                color: Highcharts.getOptions().colors[0]
            }
        }

    }, { // Tertiary yAxis
        gridLineWidth: 0,
        title: {
            text: 'Sea-Level Pressure',
            style: {
                color: Highcharts.getOptions().colors[1]
            }
        },
        labels: {

            style: {
                color: Highcharts.getOptions().colors[1]
            }
        },
        opposite: true
    }],
    tooltip: {
        shared: true
    },
    legend: {
        layout: 'vertical',
        align: 'left',
        x: 80,
        verticalAlign: 'top',
        y: 55,
        floating: true,
        backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'
    },
    series: [{
        name: 'Rainfall',
        type: 'column',
        yAxis: 1,
        data: []

   },  {
        name: 'Temperature',
        type: 'spline',
        data: []

    }]

    $.getJSON("http://localhost:8080/TestQuartz/json/highdefault.json", function(json) {
        options.xAxis.categories = json[0]['data'];
        options.series[0] = json[1];
        options.series[1] = json[2];
        chart = new Highcharts.Chart(options);
    });
});
});

我无法创建一个JSFiddle来显示实例。

在从JSON调用数据时，能否帮助我解决错误。

代码语法不正确。你更喜欢两次运行highcharts。固定代码：

$(function () {
var options = {
    chart: {
        zoomType: 'xy',
        renderTo: 'container'
    },
    title: {
        text: 'Job Status'
    },

    xAxis: [{
        categories: [],
        crosshair: true
    }],
    yAxis: [{ // Primary yAxis
        labels: {

            style: {
                color: Highcharts.getOptions().colors[2]
            }
        },
        title: {
            text: 'Transaction Count',
            style: {
                color: Highcharts.getOptions().colors[2]
            }
        },
        opposite: true

    }, { // Secondary yAxis
        gridLineWidth: 0,
        title: {
            text: 'Time',
            style: {
                color: Highcharts.getOptions().colors[0]
            }
        },
        labels: {
            format: '{value} min',
            style: {
                color: Highcharts.getOptions().colors[0]
            }
        }

    }, { // Tertiary yAxis
        gridLineWidth: 0,
        title: {
            text: 'Sea-Level Pressure',
            style: {
                color: Highcharts.getOptions().colors[1]
            }
        },
        labels: {

            style: {
                color: Highcharts.getOptions().colors[1]
            }
        },
        opposite: true
    }],
    tooltip: {
        shared: true
    },
    legend: {
        layout: 'vertical',
        align: 'left',
        x: 80,
        verticalAlign: 'top',
        y: 55,
        floating: true,
        backgroundColor: (Highcharts.theme && Highcharts.theme.legendBackgroundColor) || '#FFFFFF'
    },
    series: [{
        name: 'Rainfall',
        type: 'column',
        yAxis: 1,
        data: []

    }, {
        name: 'Temperature',
        type: 'spline',
        data: []

    }]
};



    $.getJSON("http://localhost:8080/TestQuartz/json/highdefault.json", function (json) {
        options.xAxis[0].categories = json[0]['data'];
        options.series[0] = json[1];
        options.series[1] = json[2];
        chart = new Highcharts.Chart(options);
    });
});
