Different Color Bars for Flot Categories Bar Chart

Question

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

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.

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.

// 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"]]
    }
});

Running code:

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: {
        ticks: [[0,"Red"],[1,"Yellow"],[2,"Green"]]
    }
});

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

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]]}
];
