Datalabels For Bar Chart In Highcharts Not Displaying For Null Values In 3.0.8

I've been using the following code to set dataLabels for bar charts in Highcharts... plotOptions: { bar: { dataLabels: { enabled: true, formatte

Solution 1:

Possibly bug, reported here https://github.com/highslide-software/highcharts.com/issues/2899

Workaround: use renderer http://api.highcharts.com/highcharts#Renderer.text

Solution 2:

As Sebastian points out, this is in fact a bug. However, there is an easy fix... In highcharts.src.js, simply change the call to the pick function for getting plotX and plotY in Series.prototype.alignDataLabel (lines 16132 and 16133) to:

plotX = pick(point.plotX, 0),
plotY = pick(point.plotY, 0),

rather than

plotX = pick(point.plotX, -999),
plotY = pick(point.plotY, -999),

Hope this ends up being helpful to somebody...
