问题 I have been trying to implement the pie chart using Highcharts but am encountering an issue with the datalabels on very low resolutions being cropped. I have attempted adding a windows.resize withing the formatter: function() but that failed. Here is the code I am currently using: // Radialize the colors Highcharts.getOptions().colors = $.map(Highcharts.getOptions().colors, function(color) { return { radialGradient: { cx: 0.5, cy: 0.3, r: 0.7 }, stops: [ [0, color], [1, Highcharts.Color(color

Here is a fiddle rather
