Dates on xaxis with highcharts <p>I need to have dates on my xaxis on my chart. I collect my data through a range datepicker where the user can enter a range of 14 days. I need the first value on the xaxis to be the start date of the range and the last value to be the end date of the range. i want the the xaxis labels to read something like "27th Jan 2015" , "28th Jan 2015" or something in that direction and each tic to be 1 day. I've read the API-documentation and i've played around alot with the settings of the chart but for some reason i can not get it to work.</p> <pre><code> $('#graphColumn').highcharts({ title: { text: '', x: -20 //center }, xAxis: { categories: [dayArray[0], dayArray[1], dayArray[2], dayArray[3], dayArray[4], dayArray[5], dayArray[6], dayArray[7], dayArray[8], dayArray[9], dayArray[10], dayArray[11], dayArray[12], dayArray[13]] }, yAxis: { title: { text: '' }, plotLines: [{ value: 0, width: 1, color: '#808080' }] }, tooltip: { valueSuffix: '' }, legend: { layout: 'vertical', align: 'right', verticalAlign: 'middle', borderWidth: 0 }, credits: { enabled: false }, series: [{ showInLegend: false, name: ' ', data: series, color: '#77B7C5', marker: { symbol: 'circle' } }, { showInLegend: false, name: '1 år sedan', data: series1yearago, color: "#71C73E", marker: { symbol: 'circle' } }] }); </code></pre> <p>here is my chart. I know the xaxis has categories set now but thats only for the moment, i know it should be datetime. My series are regular int arrays with one number on each index. I would apreciate any help that could be given here!</p> <p>Edit: Here is a working jsfiddle example: <a href="http://jsfiddle.net/g0p00tLv/1" rel="nofollow">http://jsfiddle.net/g0p00tLv/1</a></p>
