Steps to Reproduce

Current Behavior

When I stack multiple line series on top of each other, you can see that they are not perfectly aligned to each other - there some gaps and overlaps on the border. Overlaps are more visible if you have some series (or some regions in those series) equal to 0.

Expected Behavior

No gaps nor overlaps in stacked area charts are visible, the series are perfectly placed on top of each other.

Environment

- OS: MacOS 10.15.7
- Browser: Chrome 99.0.4844.84

Any additional comments?

No response

Well, after I used null instead of zero and added lineStyle.width = 1 and areaStyle.opacity = 1, most issues seems to be gone.
