如何更改高图表中图表区域的背景颜色？

Question

I'm using Highcharts JS. I want to change the colors of the line, the dots and background color of the area underneath the line.

I tried many ways but none of them worked. I've create a project on JsFiddle so that you can see the code and change it if you have the solution to help me solve this problem.

Sample on JSFiddle:

line Chart using highcharts

My code:

var chart = new Highcharts.Chart({

            chart: {
                renderTo: 'charts',
                type: 'area',
                backgroundColor: '#4b0e26',
                style: {
                    fontFamily: 'CairoFont',
                    color: "#ffffff",
                }
            },

            xAxis: {
                categories: [
                    'يناير',
                    'فبراير',
                    'مارس',
                    'إبريل',
                    'مايو',
                    'يوليو',
                    'يونيو',
                    'أغسطس',
                    'سبتمبر',
                    'أكتوبر',
                    'نوفمبر',
                    'ديسمبر',
                ],
                reversed: true,
                lineColor: '#fff',
                tickColor: '#fff',
                labels: {
                    style: {
                        color: '#fff',

                    }
                },
            },

            yAxis: {

                    useHTML: Highcharts.hasBidiBug,

                },
                opposite: true,

            },

            legend: {

                    [9, 50.4],
                    [10, 230.4],
                    [11, 110.4],
                    [12, 500.4],
                ],

            }]

        });

If you want to adjust the color for this series, you can use https://api.highcharts.com/highcharts/plotOptions.series.color . So you would just set your series like:

series: [{
    showInLegend: false,
    data: [
        [0, 29.9],
        [1, 71.5],
        [3, 106.4],
        [4, 300.4],
        [5, 400.4],
        [6, 20.4],
        [7, 40.4],
        [8, 120.4],
        [9, 50.4],
        [10, 230.4],
        [11, 110.4],
        [12, 500.4],
    ],
    color: '#ff0000'
}]

See a working demo at https://jsfiddle.net/gh/get/library/pure/highcharts/highcharts/tree/master/samples/highcharts/plotoptions/series-color-specific/ from their documentation or https://jsfiddle.net/pkcrt5q2/ for your specific example.

Additionally, you can set this as a global option as described at https://api.highcharts.com/highcharts/colors .

Highcharts.setOptions({
    colors: ['#ff0000']
});
