Enum Fill 

pub enum Fill {
    ToZeroY,
    ToZeroX,
    ToNextY,
    ToNextX,
    ToSelf,
    ToNext,
    None,
}

An enumeration representing different fill modes for area traces in plots.

The Fill enum specifies how the area under or between traces should be filled in plots like scatter plots, line plots, and polar scatter plots.

Example

use plotlars::{Fill, Mode, Plot, Rgb, ScatterPolar, Text};
use polars::prelude::*;

let angles: Vec<f64> = (0..=360).step_by(10).map(|x| x as f64).collect();
let radii: Vec<f64> = angles.iter()
    .map(|&angle| 5.0 + 3.0 * (angle * std::f64::consts::PI / 180.0).sin())
    .collect();

let dataset = DataFrame::new(vec![
    Column::new("angle".into(), angles),
    Column::new("radius".into(), radii),
])
.unwrap();

ScatterPolar::builder()
    .data(&dataset)
    .theta("angle")
    .r("radius")
    .mode(Mode::Lines)
    .fill(Fill::ToSelf)  // Fill the area enclosed by the trace
    .color(Rgb(135, 206, 250))
    .opacity(0.6)
    .plot_title(Text::from("Filled Polar Area Chart"))
    .build()
    .plot();

Variants

ToZeroY

Fill area from the trace to y=0 (horizontal axis)

ToZeroX

Fill area from the trace to x=0 (vertical axis)

ToNextY

Fill area between this trace and the next trace along the y-direction

ToNextX

Fill area between this trace and the next trace along the x-direction

ToSelf

Fill the area enclosed by the trace (connecting the last point to the first)

ToNext

Fill area between this trace and the next trace

None

Do not fill any area
