Struct HistogramLayer 

pub struct HistogramLayer<'a> {
    pub bins: &'a [u64],
    pub color: Srgba8,
}

Available on crate feature debug-window only.

One translucent histogram layer in a multi-layer plot.

bins is borrowed (it’s just a slice into a Histogram’s bin counts) so layers are cheap to construct and keep no ownership of the histogram itself.

The renderer treats color.a as straight (non-premultiplied) alpha. Lower alpha values let underlying layers show through — pick ~120..180 for typical 2–3 layer overlays.

Fields

bins: &'a [u64]

Bin counts to draw, one entry per bar.

color: Srgba8

Bar fill colour (RGBA, straight alpha).

Implementations

impl<'a> HistogramLayer<'a>

pub fn new(bins: &'a [u64], color: Srgba8) -> Self

Build a layer from raw bins and a colour.

pub fn from_histogram<S, V>(h: &'a Histogram<S, V>, color: Srgba8) -> Self

Build a layer from a Histogram and a colour.

Equivalent to HistogramLayer::new(h.bins(), color). Generic over both the strategy S and the channel value type V, because only the strategy-independent bins() slice is read.

Trait Implementations

Performs copy-assignment from source.
