According to API document of Highchart: https://api.highcharts.com/highcharts/plotOptions.column.borderRadius
But I can't find solution to apply borderRadius only for Top Side of column.
plotOptions: {
column: {
borderRadius: 10 // How to make it only for top side. Don't apply it to bottom side ?
}
},
Sample Image
Use this highcharts-border-radius plugin.
$(function() {
'use strict';
(function(factory) {
if (typeof module === 'object' && module.exports) {
module.exports = factory;
} else {
factory(Highcharts);
}
}(function(Highcharts) {
(function(H) {
H.wrap(H.seriesTypes.column.prototype, 'translate', function(proceed) {
const options = this.options;
const topMargin = options.topMargin || 0;
const bottomMargin = options.bottomMargin || 0;
proceed.call(this);
H.each(this.points, function(point) {
if (options.borderRadiusTopLeft || options.borderRadiusTopRight || options.borderRadiusBottomRight || options.borderRadiusBottomLeft) {
const w = point.shapeArgs.width;
const h = point.shapeArgs.height;
const x = point.shapeArgs.x;
const y = point.shapeArgs.y;
let radiusTopLeft = H.relativeLength(options.borderRadiusTopLeft || 0, w);
let radiusTopRight = H.relativeLength(options.borderRadiusTopRight || 0, w);
let radiusBottomRight = H.relativeLength(options.borderRadiusBottomRight || 0, w);
let radiusBottomLeft = H.relativeLength(options.borderRadiusBottomLeft || 0, w);
const maxR = Math.min(w, h) / 2
radiusTopLeft = radiusTopLeft > maxR ? maxR : radiusTopLeft;
radiusTopRight = radiusTopRight > maxR ? maxR : radiusTopRight;
radiusBottomRight = radiusBottomRight > maxR ? maxR : radiusBottomRight;
radiusBottomLeft = radiusBottomLeft > maxR ? maxR : radiusBottomLeft;
point.dlBox = point.shapeArgs;
point.shapeType = 'path';
point.shapeArgs = {
d: [
'M', x + radiusTopLeft, y + topMargin,
'L', x + w - radiusTopRight, y + topMargin,
'C', x + w - radiusTopRight / 2, y, x + w, y + radiusTopRight / 2, x + w, y + radiusTopRight,
'L', x + w, y + h - radiusBottomRight,
'C', x + w, y + h - radiusBottomRight / 2, x + w - radiusBottomRight / 2, y + h, x + w - radiusBottomRight, y + h + bottomMargin,
'L', x + radiusBottomLeft, y + h + bottomMargin,
'C', x + radiusBottomLeft / 2, y + h, x, y + h - radiusBottomLeft / 2, x, y + h - radiusBottomLeft,
'L', x, y + radiusTopLeft,
'C', x, y + radiusTopLeft / 2, x + radiusTopLeft / 2, y, x + radiusTopLeft, y,
'Z'
]
};
}
});
});
}(Highcharts));
}));
Highcharts.chart('container', {
