Lens would like to have the ability to create stacked area/line charts with null y1 data.
#388
Describe the solution you'd like
The solution would be to use the fit function logic implemented in the non-stacked charts.
Describe alternatives you've considered
Currently, the workaround is to fill the null data in kibana or have a strange-looking chart

Additional context
To do this for stacked charts requires each successive series to know the values of the series below at that point. If series a has no explicit value at x = 1 but has an interpolated value of 2 based on the bounding values, then we need to first find the missing value to enable stacking of series b at x=1.
Further complications come into play when adding a curve type to the series, where the calculated value is not exact.
