[Highcharts Pie Chart](#)
The following example demonstrates a gradient pie chart.
We have already learned the basic configuration syntax of Highcharts in previous chapters. Next, let's look at other configurations.

## Configuration
### colors Configuration
Use the `Highcharts.getOptions().colors` property to configure colors.
```javascript
// Color fill
Highcharts.getOptions().colors = Highcharts.map(Highcharts.getOptions().colors, function (color) {
return {
radialGradient: { cx: 0.5, cy: 0.3, r: 0.7 },
stops: [
[0, color],
[1, Highcharts.Color(color).brighten(-0.3).get('rgb')] // darken
]
};
});
### Example
Filename: `highcharts_pie_gradient.htm`
$(document).ready(function() {
var chart = {
plotBackgroundColor: null,
plotBorderWidth: null,
plotShadow: false
};
var title = {
text: 'Browser market shares at a specific website, 2014'
};
var tooltip = {
pointFormat: '{series.name}: {point.percentage:.1f}%'
};
var plotOptions = {
pie: {
allowPointSelect: true,
cursor: 'pointer',
dataLabels: {
enabled: true,
format: '{point.name}%: {point.percentage:.1f} %',
style: {
color: (Highcharts.theme && Highcharts.theme.contrastTextColor) || 'black'
}
}
}
};
var 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]
]
}];
// Radialize the colors
Highcharts.getOptions().colors = Highcharts.map(Highcharts.getOptions().colors, function (color) {
return {
radialGradient: { cx: 0.5, cy: 0.3, r: 0.7 },
stops: [
[0, color],
[1, Highcharts.Color(color).brighten(-0.3).get('rgb')] // darken
]
};
});
var json = {};
json.chart = chart;
json.title = title;
json.tooltip = tooltip;
json.series = series;
json.plotOptions = plotOptions;
$('#container').highcharts(json);
});
The output of the above example is:
