HighStock doesn't work with gapsize the same way - highcharts

Question

I have some data that was taken every minute. But there are irregular gaps in it. I'm using stockchart (v6.0.5) with the 'line' chart type and my xAxis is 'datetime'. I want that the gaps don't cut the xAxis in pieces but rather reflect the time that has passed as in http://jsfiddle.net/VwkHu/177/ .
I don't really want to fill in Null values in my dataset as the gaps can be large.
How can I get this behavior with stockchart?
BTW:
If I change in the upper mentioned fiddle to stock chart by adding StockChart the following way
...
$('#container').highcharts('StockChart',{
...
then the gaps don't reflect the size of the actual gap in the data but are constant or equal the gapsize.

Answer 1

Using highstock, you need to set ordinal: false to keep missing times in the chart.
In an ordinal axis, the points are equally spaced in the chart regardless of the actual time or x distance between them. This means that missing data for nights or weekends will not take up space in the chart.
Like this:
xAxis: {
ordinal: false,
...
},
$(function() {
$('#container').highcharts('StockChart',{
chart: {
type: 'line'
},
title: {
text: 'Snow depth at Vikjafjellet, Norway'
},
subtitle: {
text: 'Irregular time data in Highcharts JS'
},
xAxis: {
type: 'datetime',
dateTimeLabelFormats: { // don't display the dummy year
month: '%e. %b',
year: '%b'
},
title: {
text: 'Date'
},
ordinal: false
},
yAxis: {
title: {
text: 'Snow depth (m)'
},
min: 0
},
tooltip: {
headerFormat: '<b>{series.name}</b><br>',
pointFormat: '{point.x:%e. %b}: {point.y:.2f} m'
},
series: [{
name: 'Winter 2007-2008',
gapSize: 5,
//connectNulls: true,
// Define the data points. All series have a dummy year
// of 1970/71 in order to be compared on the same x axis. Note
// that in JavaScript, months start at 0 for January, 1 for February etc.
