Can someone help me with my Highcharts issue? On my chart, the red labels have a white glow behind them in Chrome and Firefox. How can I get rid of that glow or change it to blue so it blends in better?
I've tried using various properties like shadow, backgroundColor, but I couldn't find the one defining that glow behind the text. Here is a snippet from the API documentation: http://api.highcharts.com/highcharts#plotOptions.column.dataLabels
plotOptions: {
columnrange: {
dataLabels: {
enabled: true,
color: 'red',
inside: false,
xHigh: -45,
xLow: -9999999,
shadow: "#ff0000",
formatter: function () {
if (this.point.high) {
var myDate = new Date(this.y);
var newDateMs = Date.UTC(myDate.getUTCFullYear(),myDate.getUTCMonth(),myDate.getUTCDate());
return '<b>' + Highcharts.dateFormat('%m/%e',newDateMs) + '</b>';
} else {
return null;
}
}
}
}
}
