php - 将 Highchart 转换为多个 y 轴

Question

我有一个使用 Highcharts 和来自 mySQL 数据库的数据的工作图。我现在需要它来查看不同轴上的线条，以便更好地布置图表。

这是我的代码和 JSFiddle，用于我的数据图表:

http://jsfiddle.net/petenaylor/tGfau/3/

(function($){ // encapsulate jQuery

$(function() {
var seriesOptions = [],
    yAxisOptions = [],
    seriesCounter = 0,
    names = ['Electric', 'Oil', 'Gas'],
    colors = Highcharts.getOptions().colors;

$.each(names, function(i, name) {

    $(function() {

$.getJSON('http://www.highcharts.com/samples/data/jsonp.php?filename=aapl-c.json&callback=?', function(data) {
    // Create the chart
    window.chart = new Highcharts.StockChart({
        chart : {
            renderTo : 'container',
            zoomType: 'x'
        },

        rangeSelector : {
            selected : 12
        },

        title : {
            text : 'Energy Prices'
        },

        series : [{
            name : 'Electric',

            <?php 
            $result = mysql_query (" SELECT * FROM energyprices ORDER BY id ASC") or die (mysql_error());
            while ($row = mysql_fetch_array($result)) {
            extract($row);
            $date = strtotime($row['pDate']);
            $date = $date."000"; // convert from Unix timestamp to JavaScript time
            $data1[] = "[$date, $electric]";
            }
            ?>


            data: [<?php echo join($data1, ',') ?>],
            tooltip: {
                valueDecimals: 2
            }
        },{
            name : 'Oil',


            <?php 
            $result = mysql_query (" SELECT * FROM energyprices ORDER BY id ASC") or die (mysql_error());
            while ($row = mysql_fetch_array($result)) {
            extract($row);
            $date = strtotime($row['pDate']);
            $date = $date."000"; // convert from Unix timestamp to JavaScript time
            $data2[] = "[$date, $oil]";
            }
            ?>


            data: [<?php echo join($data2, ',') ?>],
            tooltip: {
                valueDecimals: 2
            }
        },{
            name : 'Gas',


            <?php 
            $result = mysql_query (" SELECT * FROM energyprices ORDER BY id ASC") or die (mysql_error());
            while ($row = mysql_fetch_array($result)) {
            extract($row);
            $date = strtotime($row['pDate']);
            $date = $date."000"; // convert from Unix timestamp to JavaScript time
            $data3[] = "[$date, $gas]";
            }
            ?>


            data: [<?php echo join($data3, ',') ?>],
            tooltip: {
                valueDecimals: 2
            }
        }]
    });
});

});

});



// create the chart when all data is loaded
function createChart() {

    chart = new Highcharts.StockChart({
        chart: {
            renderTo: 'container'
        },

        rangeSelector: {
            selected: 4
        },









        /*yAxis: {
            labels: {
                formatter: function() {
                    return (this.value > 0 ? '+' : '') + this.value + '%';
                }
            },

            plotLines: [{

            }]

        yAxis: [{ // Primary yAxis
            labels: {
                formatter: function() {
                    return (this.value > 0 ? '+' : '') + this.value + '%';
                },
                style: {
                    color: '#89A54E'
                }
            },
            title: {
                text: 'Electric',
                style: {
                    color: '#89A54E'
                }
            },
            opposite: true

        }, { // Secondary yAxis
            gridLineWidth: 0,
            title: {
                text: 'Oil',
                style: {
                    color: '#4572A7'
                }
            },
            labels: {
                formatter: function() {
                    return this.value;
                },
                style: {
                    color: '#4572A7'
                }
            }

        }, { // Tertiary yAxis
            gridLineWidth: 0,
            title: {
                text: 'Gas',
                style: {
                    color: '#AA4643'
                }
            },
            labels: {
                formatter: function() {
                    return this.value;
                },
                style: {
                    color: '#AA4643'
                }
            },
            opposite: true
        }],









        plotOptions: {
            series: {
                compare: 'percent'
            }
        },

        tooltip: {
            pointFormat: '<span style="color:{series.color}">{series.name}</span>: <b>{point.y}</b> ({point.change}%)<br/>',
            valueDecimals: 2
        },

        series: seriesOptions
    });
}

});
})(jQuery);

如您所见，它可以正常工作，但是，我需要它像下面的示例一样运行。重要的是我有 y 轴显示值并且缩放必须有效。我试图用我自己的数据调整下面的代码，但我得到了脚本无响应的问题。我认为我的数据太多，图表无法处理。

有人能帮忙吗？

我认为这就是您想要的:http://jsfiddle.net/mxrhS/

我通过定义 3 个 yaxis，然后将每个系列设置为使用不同的 yaxis 来做到这一点:

yAxis:[{opposite:false},{opposite:true},{opposite:true,offset:50}],

和

series: [{
                        name: 'Electric',
                        yAxis:0,
