Struct PieChartPlot 

pub struct PieChartPlot<'a> { /* private fields */ }

Builder for pie chart plots

Implementations

impl<'a> PieChartPlot<'a>

pub fn new( label_ids: Vec<&'a str>, values: &'a [f64], center_x: f64, center_y: f64, radius: f64, ) -> Self

Create a new pie chart plot

Arguments

• label_ids - Labels for each slice of the pie
• values - Values for each slice
• center_x - X coordinate of the pie center in plot units
• center_y - Y coordinate of the pie center in plot units
• radius - Radius of the pie in plot units

pub fn with_label_format(self, fmt: Option<&'a str>) -> Self

Set the label format for slice values (e.g., “%.1f”, “%.0f%%”) Set to None to disable labels

pub fn with_start_angle(self, angle: f64) -> Self

Set the starting angle in degrees (default: 90.0)

pub fn with_flags(self, flags: PieChartFlags) -> Self

Set pie chart flags for customization

pub fn normalize(self) -> Self

Normalize the pie chart values (force full circle even if sum < 1.0)

pub fn ignore_hidden(self) -> Self

Ignore hidden slices when drawing (as if they were not there)

pub fn exploding(self) -> Self

Enable exploding effect for legend-hovered slices

pub fn validate(&self) -> Result<(), PlotError>

Validate the plot data
