Apexcharts.js: Interpolate or duplicate missing data values

[pribilinskiy]

AFAIK currently there's no way to draw lines on missing data on line charts, only points are drawn.

This doesn't look alright when there's many missing data

Although one can fill that data by specifying interpolated values or repeating former value it would be nice to have an option to just have an Apex charts option on how these null values should be handled.

And there's no way to set a different stroke for such "filled" line segments.

I would suggest the following:

options:
  nullValues: {
    fill: false | 'interpolate' | 'repeat',
    stroke: {
      width: 2,
      dashSpacing: 5,
    }
  }

Alternative option title could be seriesNulls or seriesEmptyValueHandling

+1, you can still pre-process data to drop null value, but that's definitely a required feature

Replacing null values with the former values while drawing seems like an appropriate way to handle it. I will research more on what are other options and see the possibilities of adding this feature.

Check python pandas interpolate documentation if you want to see more options ;-)

This would be very helpful!

Similar to #747 with more details on how this feature would look like.

@junedchhipa any update on this issue?

Is there any plans to add a feature improvement for this?
It seems this issue links to #747, and vice versa, with no clear resolution or intention.
Thanks! 😃
