Highcharts : labels inside columnrange bar

highcharts, label, range

Solution

The use of the "inside" propriety is indeed relevant here. But I had to bypass the bug inherent to its use (see comment to last answer).

Here is a piece of code that works for datalabels. There still is a zIndex issue with the tool tips, and I'll try to post a more complete solution soon. http://jsfiddle.net/SineDie/TREwr/1/

dataLabels: {
        inside: true,
        enabled: true,
        useHTML: true,
        formatter: function () {
             if (this.y === this.point.low) {
                    var l = '<div style="text-align:center;color:black;width:' + (this.point.plotLow - this.point.plotHigh) + 'px">' 
                        + Highcharts.dateFormat('%Y', this.point.low) + ' - '
                        + this.point.name;
                    // to avoid marking as dead if still living... 
                    if (new Date().setHours(0, 0, 0, 0) !== new Date(this.point.high).setHours(0, 0, 0, 0))
                         l += ' - ' + Highcharts.dateFormat('%Y', this.point.high);
                    l += '</div>';
                    return l;
                }
             else return '';
        }
   }

Problem

I am using the columnrange type from Highcharts-more. The default data labels formatter puts the min / max data at both ends of the range, which is nice. Is there a way to attach another label to each point? (for example : the data name, right in the middle of the bar) Please see my work at: JSFiddle This is a family tree with life ranges. I'd like to display the names shown in tooltips at the center of bars. (FYI I tried to overload the chart with text using the renderer : it worked... but the texts were attached to the chart, not to the points, and zooming left them in place, while the points moved around. Is there maybe a way to attach text labels to the each point on the chart onLoad event?) Thank you. ``` $(function () { $('#container').highcharts({ chart: { type: 'columnrange', inverted: true, marginLeft: 40, zoomType: 'xy' }, title: { text: 'My family tree' }, xAxis: { labels: { enabled: false }, min: 0, max: 10 }, yAxis: { type: 'datetime', min: new Date().setYear(1900).valueOf(), max: new Date().valueOf(), title: { text: 'Year' }, endOnTick: false }, legend: { enabled: false }, plotOptions: { columnrange: { grouping: false, pointPadding: 0, dataLabels: { enabled: true, useHTML: true, formatter: function () { if (new Date().setHours(0, 0, 0, 0) !== new Date(this.y).setHours(0, 0, 0, 0)) return '<span style="color:black">' + Highcharts.dateFormat('%Y', this.y) + '</span>'; else return ''; } } } }, tooltip: { headerFormat: '{series.name}<br/>', formatter: function () { var l = this.point.name + '<br/>' + Highcharts.dateFormat('%e/%m/%Y', this.point.low); if (new Date().setHours(0, 0, 0, 0) !== new Date(this.point.high).setHours(0, 0, 0, 0)) l += '<br/>' + Highcharts.dateFormat('%e/%m/%Y', this.point.high); return l; } }, series: [{ color: 'rgb(100,100,255)', pointWidth: 150, data: [{ name: 'Yann B', low: Date.UTC(1976, 1, 27), high: new Date().valueOf(), x: 1 * 10 / 2 }] }, { color: 'rgb(150,150,255)', pointWidth: 70, data: [{ name: 'Jean-Yves B', low: Date.UTC(1947, 3, 26), high: Date.UTC(2006, 2, 10), x: 1 * 10 / 4 }, { name: 'Josiane M', low: Date.UTC(1946, 8, 21), high: Date.UTC(1998, 11, 26), x: 3 * 10 / 4 }] }, { color: 'rgb(200,200,255)', pointWidth: 30, data: [{ name: 'Guillaume B', low: Date.UTC(1907, 7, 4), high: Date.UTC(1988, 1, 11), x: 1 * 10 / 8 }, { name: 'Marie-Jeanne S', low: Date.UTC(1911, 7, 17), high: Date.UTC(1986, 2, 3), x: 3 * 10 / 8 }, { name: 'Joseph M', low: Date.UTC(1921, 3, 11), high: Date.UTC(1996, 4, 23), x: 5 * 10 / 8 }, { name: 'Marie K', low: Date.UTC(1925, 4, 4), high: new Date().valueOf(), x: 7 * 10 / 8 }] }] }); }); ```
