Chart.js: [Help] - Line charts: any way to prevent discontinuous line when null data ?

[mbrehinier]

I have two lines to display on a chart, but with different labels, is there any way to prevent the discontinuous line when null values are passed ?
When null values, I'd like the line to extrapolate the value and draw the line to the next point.

Starting in v2.1.5 this is possible. I can't recall the name of the option off the top of my head, but looking in the doc files is a good start

I did look in the doc files, but could not find anything related to this option, neither in the chart configuration nor in the chart line options...

[etimberg]

The option is called spanGaps

so this will enabled it

options: {
  spanGaps: true
}

Thanks for the option name, but it is still not working:

The option has to be passed to the dataset, but with a line chart, and a tension, it is still not working.
If I pass the tension to 0, it works.

Is it normal ?

It really should apply to all types of lines. I will look into it

This still seem to not be working correctly if the beginning of the array begins with null values. I'll make a codepen tomorrow, right now I'm about to fall asleep.
