基于价值的Highcharts更改条形颜色

Question

我正在使用Highcharts并且想知道是否有可能在条形图中获得前3个结果,以便在图表的其余部分使用不同的颜色条？我正在从CSV文件填充图表.

这是我的javascript:

$(document).ready(function() {

        var options = {
            chart: {
                renderTo: 'container',
                defaultSeriesType: 'bar'
            },
            title: {
                text: 'Spiritual Gifts Results'
            },
            colors: [
                '#3BBEE3'
            ],
            xAxis: {
                categories: []
            },

            yAxis: {
                title: {
                    text: 'Service'
                }
            },
            series: []
        };

        var data = document.getElementById("<%= hdn_Data.ClientID %>");
        // Split the lines
        if (data.value != "") {
            var lines = data.value.split('\n');

            // Iterate over the lines and add categories or series
            $.each(lines, function(lineNo, line) {
                var items = line.split(',');
                // header line containes categories
                if (lineNo == 0) {
                    $.each(items, function(itemNo, item) {
                        if (itemNo > 0) options.xAxis.categories.push(item);
                    });
                }
                // the rest of the lines contain data with their name in the first position
                else {
                    var series = {
                        data: []
                    };
                    $.each(items, function(itemNo, item) {
                        if (itemNo == 0) {
                            series.name = item;
                        } else {
                            series.data.push(parseFloat(item));
                        }
                    });

                    options.series.push(series);

                }

            });

            // Create the chart
            var chart1 = new Highcharts.Chart(options);
        }
    });

以下是CSV示例:

Categories,Administration,Evangelism,Mercy,Shepherding,Leadership,Wisdom,Teaching
Total Points,11,5,4,4,3,2,1

所以在这个例子中,我喜欢'管理','布道'和'怜悯'有'蓝色条形',而'牧羊','领导'等有'红色条形'.

这可能吗？

Answer 1

这是一个例子

data: [
  { y: 34.4, color: 'red'},   // this point is red
  21.8,                        // default blue
  {y: 20.1, color: '#aaff99'}, // this will be greenish
  20                           // default blue
]                             

Answer 2

基于OP的评论,打破了我以前的答案.

就像你在做的那样

series.name = item; 

和

series.data.push(parseFloat(item));

同样聪明,你可以这样做,

series.color: '#f6f6f6'

(在你的循环中你可以根据你的条件改变颜色)

你可以做,

$(document).ready(function() {

    var options = {
        chart: {
            renderTo: 'container',
            defaultSeriesType: 'bar'
        },
        title: {
            text: 'Spiritual Gifts Results'
        },
        colors: [
            '#3BBEE3'
            ],
        xAxis: {
            categories: []
        },

        yAxis: {
            title: {
                text: 'Service'
            }
        },
        series: []
    };

    var data = document.getElementById("hdn_Data");
    // Split the lines
    if (data.value != "") {
        var lines = data.value.split('\n');

        // Iterate over the lines and add categories or series
        $.each(lines, function(lineNo, line) {
            var items = line.split(',');
            // header line containes categories
            if (lineNo == 0) {
                $.each(items, function(itemNo, item) {
                    if (itemNo > 0) options.xAxis.categories.push(item);
                });
            }
            // the rest of the lines contain data with their name in the first position
            else {
                var series = {
                    data: []
                };
                $.each(items, function(itemNo, item) {
                    var data = {};
                    if (itemNo == 0) {
                        series.name = item;
                    } else {
                        data.y = parseFloat(item);
                        if (itemNo <= 3) {
                            data.color = 'Gray';
                        }
                        else {
                            data.color = '#3BBEE3';
                        }
                        series.data.push(data);
                    }
                });
                options.series.push(series);
              }
            });

            // Create the chart
            var chart1 = new Highcharts.Chart(options);
        }
    });

参考这个,你可以data用3种方式给出.我用过第三个.
