data class BarBarsStyle(val color: Color, val colors: ImmutableList<Color>, val gradient: ChartGradient?, val alpha: Float, val space: Dp, val minBarWidth: Dp)

Bar visual configuration shared by vertical bar and histogram charts.

BarChartDefaults

object BarChartDefaults

Defaults factory for BarChartStyle. All parameters have theme-aware defaults.

BarChartStyle

@Stable

class BarChartStyle(val chartContainerStyle: ChartContainerStyle, val bars: BarBarsStyle, val range: BarRangeStyle, val axes: AxesStyle, val selection: BarSelectionStyle, val zoomControlsVisible: Boolean)

Immutable v3 style for vertical io.github.hdcharts.bar.BarChart.

BarRangeStyle

@Immutable

data class BarRangeStyle(val min: Double?, val max: Double?)

Optional fixed Y-axis range for vertical bar and histogram charts.

BarSelectionStyle

@Immutable

data class BarSelectionStyle(val visible: Boolean, val color: Color, val width: Dp, val unselectedAlpha: Float)

Selection indicator configuration for vertical bar and histogram charts.

ChartContainerDefaults

object ChartContainerDefaults

An object that provides default styles for a chart container.

ChartContainerStyle

@Immutable

class ChartContainerStyle(val styleTitle: TextStyle, val contentPadding: Dp, val styleSubtitle: TextStyle = TextStyle( fontSize = StyleDefaults.subtitleSize, fontWeight = StyleDefaults.subtitleWeight, textAlign = TextAlign.Start, ))

Presentation-only container style shared by every chart.

ChartGradient

@Immutable

sealed interface ChartGradient

A gradient that paints a chart shape, such as a bar or stacked area layer.

ChartGradients

object ChartGradients

Ready-made ChartGradients with evenly spaced colors.

GradientPoint

@Immutable

data class GradientPoint(val x: Float, val y: Float)

A position as fractions of a gradient's bounds: (0, 0) is the top-left corner and (1, 1) the bottom-right. Values outside 0..1 sit outside the bounds.

GradientSpan

enum GradientSpan : Enum<GradientSpan>

The bounds a ChartGradient's positions are fractions of.

GradientStop

@Immutable

sealed interface GradientStop

A color at offset along a gradient.

GridDefaults

object GridDefaults

Shared defaults for GridStyle.

GridStyle

@Immutable

data class GridStyle(val visible: Boolean, val steps: Int, val color: Color, val lineWidth: Dp)

Horizontal grid configuration shared by charts with a numeric Y axis.

HistogramChartDefaults

object HistogramChartDefaults

Defaults factory for HistogramChartStyle. Histograms render pre-binned values (one Double per bin) at equal visual widths and a zero baseline by default.

HistogramChartStyle

@Stable

class HistogramChartStyle(val chartContainerStyle: ChartContainerStyle, val bars: BarBarsStyle, val range: BarRangeStyle, val axes: AxesStyle, val selection: BarSelectionStyle, val zoomControlsVisible: Boolean)

Immutable v3 style for io.github.hdcharts.histogram.HistogramChart.

LegendDefaults

object LegendDefaults

Shared defaults for LegendStyle.

LegendStyle

@Immutable

data class LegendStyle(val visible: Boolean)

Shared legend visibility configuration.

StyleDefaults

object StyleDefaults

Every chart style default in one place, so the same element looks the same in every chart.

Functions

clamp

fun ChartGradient.clamp(): ChartGradient?

Returns this made drawable, or null when it cannot be drawn, so the shape is solid.

fun AxesStyle.clamp(density: Density): AxesStyle

Clamps stroke widths and grid steps. Label sizes pass through for validation.

fun BarChartStyle.clamp(density: Density): BarChartStyle

Returns this with alphas, sizes, and grid steps clamped to drawable values.

fun GridStyle.clamp(density: Density): GridStyle

Returns this with GridStyle.steps and GridStyle.lineWidth clamped. Names every field instead of using copy, so a field added to the constructor fails to compile here until it is dealt with.
