javascript - Show gap of missing data with Highstock -

using highstock chart sorted time serie: [[timestamp, value], ...]

the datasource sampled @ irregular intervals. result distances between 2 points (in time axis) varies.

if 2 adjacent points separated more 5 minutes want show gap in chart.

using gapsize option doesn't work, because doesn't allows specify 'size' of gap function of time.

showing gaps part of highstock, need way specify fixed amount of time (5 minutes). ideas?

btw, beside plot works great.

here's unclean way "manipulate" gapsize work it's value amount of milliseconds required create gap.

(function (h) {     // wrap getsegments change gapsize functionality work based on time (milliseconds)     h.wrap(h.series.prototype, 'getsegments', function (proceed) {         var cpr = this.xaxis.closestpointrange;         this.xaxis.closestpointrange = 1;          proceed.apply(this, array.prototype.slice.call(arguments, 1));          this.xaxis.closestpointrange = cpr;     }); }(highcharts)); 

this utilizes gapsize used within getsegments function (see source), , works based on closestpointrange of axis. wraps getsegments, sets closestpointrange 1, calls original method , resets closestpointrange original value.

with code above gaps 5 minutes this:

plotoptions: {     line: {         gapsize: 300000 // 5 minutes in milliseconds     } } 

see this jsfiddle demonstration of how may work.
