How to change the color of each marker APEXCHARTS chart in next js

Question

Do you know if there is a way to define the color of each point? Ex: { x: 'Yellow', y: [2100, 3000], colors: '#808080',} because it is set by default for all markers: plotOptions > dumbbellColors, I would like a color for each marker. documentation is confusing

Answer 1

The option plotOptions.bar.dumbbellColors is an array that allows you to set different colors, but each item in that array sets the start and end markers colors for a series. So, if there are no reasons that prevent you to set each segment as a separate series, adding the option plotOptions.bar.rangeBarGroupRows = true to prevent segments of the same x but different series to be offset waterfall-style, you can have markers colored differently.

Here's an example (I set the colors of the markers that are covered to transparent rgba(0,0,0,0)):

const options = {
    series: [{
        data: [{x: 'Amarela', y: [2100, 3000]}]
    }, {
        data: [{x: 'Amarela', y: [3000, 5000]}]
    }, {
        data: [{x: 'Amarela', y: [5000, 6500]}]
    }, {
        data: [{x: 'Amarela', y: [6500, 8000]}]
    }, {
        data: [{x: 'Branca', y: [2100, 5000]}]
    }, {
        data: [{x: 'Branca', y: [5000, 8000]}]
    }, {
        data: [{x: 'Indígina', y: [2100, 8000]}]
    }, {
        data: [{x: 'Parda', y: [2100, 8000]}]
    }, {
        data: [{x: 'Preta', y: [2100, 8000]}]
    }],
    chart: {
        type: 'rangeBar',
        height: 380,
        zoom: {
            enabled: false
        }
    },
    colors: ['#808080', '#808080'],
    plotOptions: {
        bar: {
            horizontal: true,
            isDumbbell: true,
            rangeBarGroupRows: true,
            dumbbellColors: [
                ['#EC7D31', 'rgba(0,0,0,0)'], // start and end color for markers of series 0
                ['#7D31EC', 'rgba(0,0,0,0)'], // start and end color for markers of series 1
                ['#FDCB36', 'rgba(0,0,0,0)'], // .....
                ['#FD31EC', '#36BDCB'],
                ['#2DF13C', 'rgba(0,0,0,0)'],
                ['#FF313C', '#2D3BFF'],
                ['#2DD1AC', '#BDCB36'],
                ['#7D31EC', '#433366'],
                ['#8F8F8F', '#ADCBF6']
            ]
        },
    },
    legend: {
        show: false,
        showForSingleSeries: false,
        position: 'top',
        horizontalAlign: 'left',
        customLegendItems: ['Female', 'Male'],
    },
    grid: {
        xaxis: {
            lines: {
                show: false,
            },
            labels: {
                show: false,
            },
        },
        yaxis: {
            lines: {
                show: false,
            },
            yaxis: {lines: {show: false}},
        },
    },
    xaxis: {
        labels: {
            show: false,
        },
    }
};

const chart = new ApexCharts(document.querySelector("#chart"), options);
chart.render();
