Enum PointVisibility 

pub enum PointVisibility {
    Visible,
    Hidden,
    Auto {
        min_spacing_px: f64,
    },
}

Whether a point layer’s marks are inked.

Points over a line often exist mainly as per-point hover and click targets (each mark carries its <title> and data-* attributes). On a dense series they swamp the line, so they can be drawn without ink: the mark stays in the SVG with fill-opacity="0", which browsers still hit-test (pointer-events: visiblePainted counts a painted fill of any opacity), so hover and clicks keep working.

Variants

Visible

Every point is drawn (the default).

Hidden

No point is inked.

Auto

Visible while the panel’s distinct x positions are at least min_spacing_px apart on average, hidden when denser. Decided per panel, so a facet with a short series keeps its dots.

Fields

min_spacing_px: f64

Implementations

impl PointVisibility

pub const AUTO: PointVisibility

Auto with a 3 px average spacing: a 7-day series at 15-minute resolution (672 points) is hidden on any plot narrower than ~2000 px, a 12-point monthly series stays visible down to ~36 px.
