如何在High Charts PIE数据中添加自定义颜色| 切片并想要更改切片文本

Question

Can anyone suggest me about colouring to each slice of High Charts Data.

My Code is given below also a image there. I want to put my custom color to each slice of data (for data are like Firefox, opera, chrome, IE etc.. )

and also want to remove series name ('Browser share') in this example, if I put it false "name: false" then is showing series one, I want to show it like "Firefox: 45%" on mouse hover on Firefox slice

 $(function () { $('#graph').highcharts({ chart: { plotBackgroundColor: null, plotBorderWidth: null, plotShadow: false }, title: { text: 'Browser market shares at a specific website, 2014' }, tooltip: { pointFormat: '{series.name}: <b>{point.percentage:.1f}%</b>' }, plotOptions: { pie: { allowPointSelect: true, cursor: 'pointer', dataLabels: { enabled: true, format: '<b>{point.name}</b>: {point.percentage:.1f} %', style: { color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black' } } } }, series: [{ type: 'pie', name: 'Browser share', data: [ ['Firefox', 45.0], ['IE', 26.8], { name: 'Chrome', y: 12.8, sliced: true, selected: true }, ['Safari', 8.5], ['Opera', 6.2], ['Others', 0.7] ] }] }); });

We can specify default color set which the report should as follows:

 Highcharts.getOptions().plotOptions.pie.colors=['#2f7ed8', '#0d233a',
   '#8bbc21', '#910000', '#1aadce', '#492970', '#f28f43', '#77a1e5',
    '#c42525', '#a6c96a'];

 $(function () { //Specify color set as follows Highcharts.getOptions().plotOptions.pie.colors=['#2f7ed8', '#0d233a', '#8bbc21', '#910000', '#1aadce', '#492970', '#f28f43', '#77a1e5', '#c42525', '#a6c96a']; $('#graph').highcharts({ chart: { plotBackgroundColor: null, plotBorderWidth: null, plotShadow: false }, title: { text: 'Browser market shares at a specific website, 2014' }, tooltip: { pointFormat: '<b>{point.percentage:.1f}%</b>' // updated tool tip }, plotOptions: { pie: { allowPointSelect: true, cursor: 'pointer', dataLabels: { enabled: true, format: '<b>{point.name}</b>: {point.percentage:.1f} %', style: { color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black' } } } }, series: [{ type: 'pie', name: 'Browser share', data: [ ['Firefox', 45.0], ['IE', 26.8], { name: 'Chrome', y: 12.8, sliced: true, selected: true }, ['Safari', 8.5], ['Opera', 6.2], ['Others', 0.7] ] }] }); });

To change series name in tooltip you can change pointFormat and remove reference to series.name

Example:

 tooltip: {
            pointFormat: '<b>{point.percentage:.1f}%</b>'
        },

How can I change the colors of my highcharts piechart?

Also: color can be set per data point - http://jsfiddle.net/avsdgek8/1/ or per series - http://api.highcharts.com/highcharts#plotOptions.pie.colors
