[disha-nimble]

i tried to change export button symbol using below code: Highcharts.SVGRenderer.prototype.symbols.download = function (x, y, w, h) { var path = [ // Arrow stem 'M', x + w * 0.5, y, 'L', x + w * 0.5, y + h * 0.7, // Arrow head 'M', x + w * 0.3, y + h * 0.5, 'L', x + w * 0.5, y + h * 0.7, 'L', x + w * 0.7, y + h * 0.5, // Box 'M', x, y + h * 0.9, 'L', x, y + h, 'L', x + w, y + h, 'L', x + w, y + h * 0.9 ]; return path; }; but i got an error of "Highcharts.SVGRenderer".
