我正在尝试使用 Flot for JQUery 绘制以下图表：

在此处输入图像描述

其中 A、B、C 和 D 是营销工作......

我有这个示例代码：

var data = [ ["January", 10,80], ["February", 8], ["March", 4], ["April", 13], ["May", 17], ["June", 9] ];

    $.plot("#catchart", [ data ], {
        series: {
            bars: {
                show: true,
                barWidth: 0.6,
                align: "center"
            }
        },
        xaxis: {
            mode: "categories",
            tickLength: 0
        }
    });

但这只会为每个类别绘制一列。我怎样才能让每个类别的两列“配对”或在一起？

这可以使用 categories 插件以及orderBars 插件来实现。

var data = [
    { label: "Money Spent", data: [ ["January", 10], ["February", 8], ["March", 4], ["April", 13], ["May", 17], ["June", 9] ] },
    { label: "Money Earned", data: [ ["January", 20], ["February", 30], ["March", 5], ["April", 6], ["May", 9], ["June", 9] ] }
];

$.plot("#catchart", data, {
    series: {
        bars: {
            show: true,
            barWidth: 0.2,
            lineWidth: 0,
            order: 1,
            fillColor: {
                colors: [{
                    opacity: 1
                }, {
                    opacity: 1
                }]
            }
        }
    },
    xaxis: {
        mode: "categories"
    },
    grid: {
        borderWidth: 0
    },
    colors: ["#3F48CC", "#ED1C24"]
});

这是jFiddle。
