Enum ChartData 

pub enum ChartData {
    Category {
        categories: Vec<String>,
        series: Vec<ChartSeries>,
    },
    Xy {
        series: Vec<XySeries>,
    },
}

Chart data — either category-based or XY-based.

Examples

use hwpforge_core::chart::ChartData;

let cat = ChartData::category(
    &["A", "B"],
    &[("Series1", &[10.0, 20.0])],
);
assert!(matches!(cat, ChartData::Category { .. }));

let xy = ChartData::xy(&[("Points", &[1.0, 2.0], &[3.0, 4.0])]);
assert!(matches!(xy, ChartData::Xy { .. }));

Variants

Category

Category-based data (bar, line, pie, area, radar, etc.).

Fields

categories: Vec<String>

Category labels (X-axis).

series: Vec<ChartSeries>

Data series, each with a name and values.

Xy

XY-based data (scatter, bubble).

Fields

series: Vec<XySeries>

XY series, each with name + x/y value arrays.

Implementations

impl ChartData

pub fn category(cats: &[&str], series: &[(&str, &[f64])]) -> Self

Creates category-based chart data from slices.

Examples

use hwpforge_core::chart::ChartData;

let data = ChartData::category(
    &["Jan", "Feb", "Mar"],
    &[("Revenue", &[100.0, 200.0, 300.0])],
);
match &data {
    ChartData::Category { categories, series } => {
        assert_eq!(categories.len(), 3);
        assert_eq!(series.len(), 1);
    }
    _ => unreachable!(),
}

pub fn xy(series: &[(&str, &[f64], &[f64])]) -> Self

Creates XY-based chart data from slices.

Examples

use hwpforge_core::chart::ChartData;

let data = ChartData::xy(&[("Points", &[1.0, 2.0], &[3.0, 4.0])]);
match &data {
    ChartData::Xy { series } => {
        assert_eq!(series.len(), 1);
        assert_eq!(series[0].x_values.len(), 2);
    }
    _ => unreachable!(),
}

pub fn has_no_series(&self) -> bool

Returns true if the chart data contains no series.

A chart with zero series cannot be rendered. This is checked during document validation (see ValidationError::EmptyChartData).

pub fn is_empty(&self) -> bool

👎Deprecated since 0.2.0: Use has_no_series() instead

Returns true if the chart data contains no series.

Trait Implementations

impl Clone for ChartData

fn clone(&self) -> ChartData

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChartData

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChartData

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for ChartData

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for ChartData

fn eq(&self, other: &ChartData) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for ChartData

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
