Steps to Reproduce

1. Open repro link.
   a. This is simply a chart with a time axis and a scatter series, where points appear at the leftmost and/or rightmost points on the x-axis.
2. Drag divider border to adjust chart width.

Current Behavior

Series min and max points will flicker as the chart width changes, and the points may remain hidden if the width is left in a bad spot.

Expected Behavior

The points should remain visible.

Environment

- OS: Win 11
- Browser: Chrome 113.0.5672.127
- Framework:

Any additional comments?

Any number of changes show that this should work:

• changing xAxis to a category axis (with boundaryGap: false to most closely replicate the current view)
• changing the series type to line
• setting an arbitrarily small boundaryGap: ["0.01%", "0.01%"]
  • This is the workaround I currently use, although it's not ideal and sometimes interferes with the axis labeling

Just set clip: false. See also #18656 (comment).

Thanks, that workaround works.

I see you marked the linked post as "not a bug", but based on the above bullets it seems like this is unintended behavior. Is that correct? Or if this is expected, would you mind explaining how the default clipping works and when clip: true is advantageous?

[plainheart]

@jnoyola It is similar to #16329. The edge symbols are clipped due to the tiny offset. I just found several related issues. I will consider it a bug and try to fix it later.
