apexcharts.js: Interpolate or duplicate missing data values

AFAIK currently there’s no way to draw lines on missing data on line charts, only points are drawn. https://codepen.io/anon/pen/WaxKdp

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

Check python pandas interpolate documentation if you want to see more options 😉

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.

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! 😃
