Accepted answer
I was able to achieve something close using the following:
let draw = Chart.controllers.radar.prototype.draw;
Chart.controllers.radar.prototype.draw = function() {
let chart = this.chart;
let ctx = chart.ctx;
let _stroke = ctx.stroke;
ctx.stroke = function() {
ctx.save();
ctx.shadowColor = 'rgba(3, 252, 240, 1)' //ctx.strokeStyle;
ctx.shadowBlur = 40;
ctx.shadowOffsetX = 0;
ctx.shadowOffsetY = 0;
_stroke.apply(this, arguments);
ctx.restore();
};
draw.apply(this, arguments);
ctx.stroke = _stroke;
}
