Struct Histogram 

pub struct Histogram { /* private fields */ }

Overlapping channels from ready-made bins, in a linear or logarithmic scale, with a mark at each end when too much of a channel piles up there. Where channels overlap, their colors add up, as light does, so each stays readable.

use ravenrs_core::Color;
use ravenrs_widgets::{Histogram, HistogramChannel, HistogramScale};

let red: Vec<u32> = (0..256).map(|i| (i * (256 - i)) as u32).collect();
let view = Histogram::new([HistogramChannel::new("Red", Color::rgb(0.9, 0.2, 0.2), red)])
    .scale(HistogramScale::Logarithmic)
    .zones(5);

Implementations

impl Histogram

pub fn new(channels: impl IntoIterator<Item = HistogramChannel>) -> Histogram

A histogram of these channels, 96 logical pixels tall, across its parent.

pub fn scale(self, scale: HistogramScale) -> Histogram

How counts turn into heights (Linear by default).

pub fn clip_share(self, share: f32) -> Histogram

The share of a channel that must sit in an end bin to light that end’s mark, from 0 to 1 (0.001 by default, which ignores a stray reflection).

pub fn zones(self, zones: u32) -> Histogram

Divides the width in this many equal zones, with light lines (none by default).

pub fn size(self, width: f32, height: f32) -> Histogram

Fixed size in logical pixels.

pub fn height(self, height: f32) -> Histogram

Height in logical pixels (96 by default).

pub fn label(self, label: impl Into<String>) -> Histogram

The name screen readers announce, instead of the one in Labels.

Trait Implementations

impl Clone for Histogram

fn clone(&self) -> Histogram

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Histogram

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl View for Histogram

fn build(&self, cx: &mut BuildCx<'_>) -> NodeId

Creates this view’s node for the current build.

fn type_name(&self) -> &'static str

The name the diagnostics panel shows this view’s cost under.
