set different colors for each column in highcharts

Question

I need to set different colors for each column in Highcharts graph dynamically. My Highcharts graph is:

options = {
           


        

Answer 1

Here is another solution with the latest version of Highcharts (currently 3.0).

Set the colorByPoint option to true and define the color sequence that you want.

options = {
    chart: {...},
    plotOptions: {
        column: {
            colorByPoint: true
        }
    },
    colors: [
        '#ff0000',
        '#00ff00',
        '#0000ff'
    ]
}

Here is an example based upon Highcharts Column with rotated labels demo

Answer 2

Try either of these approaches:

Approach 1:

Highcharts.setOptions({ colors: ['#3B97B2', '#67BC42', '#FF56DE', '#E6D605', '#BC36FE'] });

Approach 2:

var colors = ['#3B97B2', '#67BC42', '#FF56DE', '#E6D605', '#BC36FE', '#000'];

 $('#bar_chart').highcharts({
        chart: {
            type: 'column'              
        },
        title: {
            text: ''
        },
        subtitle: {
            text: ''
        },
        xAxis: {
            type: 'category'
        },
        yAxis: {
            title: {
                text: ''
            }
        },
        legend: {
            enabled: false
        },
        plotOptions: {
            series: {
                borderWidth: 0,
                dataLabels: {
                    enabled: false                       
                }
            }
        },         

        series: [{
            name: '',
            colorByPoint: true,
            data: [{
                name: 'Blue',
                y: 5.78,
                color: colors[0]

            }, {
                name: 'Green',
                y: 5.19,
                color: colors[1]

            }, {
                name: 'Pink',
                y: 32.11,
                color: colors[2]

            }, {
                name: 'Yellow',
                y: 10.04,
                color: colors[3]

            }, {
                name: 'Purple',
                y: 19.33,
                color: colors[4]

            }]
        }]
    });

Answer 3

When you add the value to the series.data you can also set the color using the point options e.g

series.data.push({ y: parseInt(Data[i]), color: '#FF0000' });

For more details about the point options see https://api.highcharts.com/class-reference/Highcharts.Point#color

Answer 4

i had colors from API response and 2 series. second series with dynamic colors.

following is sample to set dynamic colors while series mapping.

const response = [{
    'id': 1,
    'name': 'Mango',
    'color': '#83d8b6',
    'stock': 12.0,
    'demand': 28,
  },
  {
    id ': 2,
    'name': 'Banana',
    'color': '#d7e900',
    'stock': 12.0,
    'demand': 28,
  }
];
let chartData: {
  categories: [],
  series: []
};
chartData.categories = response.map(x => x.name);
chartData.series.push({
  name: 'Series 1',
  type: 'column',
  data: response.map(x => x.demand)
});
chartData.series.push({
  name: 'Series 2',
  type: 'column',
  data: response.map(x => ({
    y: x.stock,
    color: x.color // set color here dynamically
  }))
});
console.log('chartData: ', chartData);
