如何更改高图中条形的宽度？

Question

使用像这样的条形图,可以改变条形的宽度来表示另一个数据属性,比如水果的重量.水果越重,酒吧越厚.

你在这里玩脚本.我对其他javascript绘图库开放,只要它们是免费的,就可以做到这一点.

$(function () {
    var chart;
    $(document).ready(function() {
        chart = new Highcharts.Chart({
            chart: {
                renderTo: 'container',
                type: 'column'
            },
            title: {
                text: 'Column chart with negative values'
            },
            xAxis: {
                categories: ['Apples', 'Oranges', 'Pears', 'Grapes', 'Bananas']
            },
            tooltip: {
                formatter: function() {
                    return ''+
                        this.series.name +': '+ this.y +'';
                }
            },
            credits: {
                enabled: false
            },
            series: [{
                name: 'John',
                data: [5, 3, 4, 7, 2]
                // I would like something like this (3.5, 6 etc is the width) :
                // data: [[5, 3.4], [3, 6], [4, 3.4], [7, 2], [2, 5]]
            }, {
                name: 'Jane',
                data: [2, -2, -3, 2, 1]
            }, {
                name: 'Joe',
                data: [3, 4, 4, -2, 5]
            }]
        });
    });

});?

Answer 1

pointWidth 是您设置条形宽度所需的.尝试

plotOptions: {
            series: {
                pointWidth: 15
            }
        }

这个显示条的宽度为15px.在这里玩.刚刚对现有代码进行了编辑.

Answer 2

我使用一组面积图来模拟可变宽度列/条形图.比如说,每个栏/栏都由一个矩形区域表示.

看我的小提琴演示(http://jsfiddle.net/calfzhou/TUt2U/).

$(function () {
    var rawData = [
        { name: 'A', x: 5.2, y: 5.6 },
        { name: 'B', x: 3.9, y: 10.1 },
        { name: 'C', x: 11.5, y: 1.2 },
        { name: 'D', x: 2.4, y: 17.8 },
        { name: 'E', x: 8.1, y: 8.4 }
    ];

    function makeSeries(listOfData) {
        var sumX = 0.0;
        for (var i = 0; i < listOfData.length; i++) {
            sumX += listOfData[i].x;
        }
        var gap = sumX / rawData.length * 0.2;
        var allSeries = []
        var x = 0.0;
        for (var i = 0; i < listOfData.length; i++) {
            var data = listOfData[i];
            allSeries[i] = {
                name: data.name,
                data: [
                    [x, 0], [x, data.y],
                    {
                        x: x + data.x / 2.0,
                        y: data.y,
                        dataLabels: { enabled: true, format: data.x + ' x {y}' }
                    },
                    [x + data.x, data.y], [x + data.x, 0]
                ],
                w: data.x,
                h: data.y
            };
            x += data.x + gap;
        }
        return allSeries;
    }

    $('#container').highcharts({
        chart: { type: 'area' },
        xAxis: {
            tickLength: 0,
            labels: { enabled: false}
        },
        yAxis: {
            title: { enabled: false}
        },
        plotOptions: {
            area: {
                marker: {
                    enabled: false,
                    states: {
                        hover: { enabled: false }
                    }
                }
            }
        },
        tooltip: {
            followPointer: true,
            useHTML: true,
            headerFormat: '<span style="color: {series.color}">{series.name}</span>: ',
            pointFormat: '<span>{series.options.w} x {series.options.h}</span>'
        },
        series: makeSeries(rawData)
    });
});
