Struct PieChartPlot 

pub struct PieChartPlot<'a, F = &'static str> { /* 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

impl<'a, F: AsRef<str>> PieChartPlot<'a, F>

pub fn with_label_format<'fmt>( self, format: FloatFormat<'fmt>, ) -> PieChartPlot<'a, FloatFormat<'fmt>>

Set the validated label format for slice values.

pub fn try_label_format<'fmt>( self, format: impl Into<Cow<'fmt, str>>, ) -> Result<PieChartPlot<'a, FloatFormat<'fmt>>, FloatFormatError>

Validate and set a C-style label format for slice values.

pub fn without_value_labels(self) -> Self

Disable per-slice value 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 with_item_flags(self, flags: ItemFlags) -> Self

Set common item flags for this plot item (applies to all plot types)

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 no_slice_border(self) -> Self

Draw slices without the per-slice border stroke.

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

Validate the plot data
