Struct LineChartStyle 

pub struct LineChartStyle<C: PixelColor> {
    pub line_color: C,
    pub line_width: u32,
    pub fill_area: bool,
    pub fill_color: Option<C>,
    pub markers: Option<MarkerStyle<C>>,
    pub smooth: bool,
    pub smooth_subdivisions: u32,
}

Style configuration for line charts.

This structure contains all visual styling options for line charts, including line appearance, markers, and area fills.

Examples

use embedded_charts::prelude::*;
use embedded_graphics::pixelcolor::Rgb565;

let style = LineChartStyle {
    line_color: Rgb565::BLUE,
    line_width: 2,
    fill_area: true,
    fill_color: Some(Rgb565::CSS_LIGHT_BLUE),
    markers: Some(MarkerStyle::default()),
    smooth: false,
    smooth_subdivisions: 8,
};

Fields

line_color: C

Color of the line connecting data points.

line_width: u32

Width of the line in pixels (recommended range: 1-10).

Larger widths may impact performance on resource-constrained devices.

fill_area: bool

Whether to fill the area under the line.

When enabled, creates a filled polygon from the line to the chart baseline.

fill_color: Option<C>

Fill color for the area under the line.

Only used when fill_area is true. If None, no fill is drawn.

markers: Option<MarkerStyle<C>>

Marker style for data points.

When Some, markers are drawn at each data point. When None, no markers are shown.

smooth: bool

Whether to smooth the line using interpolation.

When enabled, creates smooth curves between data points instead of straight lines. Uses Catmull-Rom spline interpolation for balanced smoothness and performance. This feature may impact performance and is recommended for larger displays.

smooth_subdivisions: u32

Number of subdivisions for smooth curves (only used when smooth = true)
