Flot类别条形图的不同颜色条

How can you have a different color for each bar when using the "categories" mode in Flot?

在Flot中使用“类别”模式时,如何为每个条形图设置不同的颜色?

This code makes every bar the first color in colors array. I'd like each bar to be the corresponding color in the colors array.

此代码使每个条形图成为颜色数组中的第一个颜色。我希望每个条形图都是颜色数组中的相应颜色。

Current code:

var data = [["Red",1],["Yellow",2],["Green",3]];

$.plot("#placeholder1div",[data], {
    series: {
        bars: {
            show: true,
            barWidth: 0.3,
            align: "center",
            lineWidth: 0,
            fill:.75
        }
    },
    xaxis: {
        mode: "categories",
    },
    colors: ["#FF0000","#FFFF00","#00FF00"]
});

As is often my recommendation with Flot, drop the plugin and configure it up youself.

正如我对Flot的推荐,放下插件并自行配置。

// separate your 3 bars into 3 series, color is a series level option
var data = [{data: [[0,1]], color: "red"}, 
            {data: [[1,2]], color: "yellow"},
            {data: [[2,3]], color: "green"}];

$.plot("#placeholder",data, {
    series: {
        bars: {
            show: true,
            barWidth: 0.3,
            align: "center",
            lineWidth: 0,
            fill:.75
        }
    },
    xaxis: {
        // drop the categories plugin and label the ticks yourself
        // you'll thank me in the long run
        ticks: [[0,"Red"],[1,"Yellow"],[2,"Green"]]
    }
});

When you put your data you must to put the colors inside:

放置数据时,必须将颜色放入:

var data = [
    {color: '#ff00aa', data: [[0, 1]]},
    {color: 'red', data: [[1, 1]]},
    {color: 'yellow', data: [[2, 2],[3, 2]]},
    {color: 'orange', data: [[4, 2]]},
    {color: 'blue', data: [[5, 4],[6, 7]]},
    {color: '#000000', data: [[7, 1]]}
];

Use below configuration

使用以下配置

// Colors 
var color01 = '#00cde2';
var color02 = '#ffb700';
var color03 = '#7ac70c';
var color04 = '#313541';
var color05 = '#fc3232';
var color06 = '#1cb0f6';
var color07 = '#00c07f';

var data = [
            {data: [[0, 4.1]], color: color01},
            {data: [[1, 1.8]], color: color02},
            {data: [[2, 2]], color: color03},
            {data: [[3, 4.5]], color: color04},
            {data: [[4, 3.7]], color: color05},
            {data: [[5, 5.6]], color: color06},
            {data: [[6, 2.6]], color: color07}
        ];

        $.plot($("#placeholder"), data, {
            series: {
                lines: {
                    fill: false
                },
                points: {show: false},
                bars: {
                    show: true,
                    align: 'center',
                    barWidth: 0.5,
                    fill: 1,
                    lineWidth: 1
                }
            },
            xaxis: {
                tickLength: 0,
                ticks: [
                    [0, "Data One"],
                    [1, "Data Two"],
                    [2, "Data Three"],
                    [3, "Data Four"],
                    [4, "Data Five"],
                    [5, "Data Six"],
                    [6, "Data Seven"]]
            },
            yaxis: {
                min: 0
            },
            grid: {
                hoverable: true,
                backgroundColor: {
                    colors: ["#fff", "#fff"]
                },
                borderWidth: {
                    top: 1,
                    right: 1,
                    bottom: 2,
                    left: 2
                },
                borderColor: {
                    top: "#e5e5e5", 
                    right: "#e5e5e5",
                    bottom: "#a5b2c0",
                    left: "#a5b2c0"
                }
            }
        });
