Class BOBHistogramChart<T>

Namespace

BlazOrbit.Charts.Components

Assembly

BlazOrbit.Charts.dll

Histogram - distribution of a single numeric variable. Auto-bins the raw Values using BinRule and renders each bin as a vertical bar. Includes a quantile readout (Median, P95) optionally shown via the ShowQuantileLines flag.

Constructors

BOBHistogramChart()

public BOBHistogramChart()

Properties

BinCount

Bin count when BinRule is FixedCount.

[Parameter]
public int BinCount { get; set; }

Property Value

int

BinLabelFormat

Number-format used for bin label ranges. Default "G".

[Parameter]
public string? BinLabelFormat { get; set; }

Property Value

string

BinRule

Binning rule. Default Sturges.

[Parameter]
public BOBHistogramBinRule BinRule { get; set; }

Property Value

BOBHistogramBinRule

Color

Optional fill color override; falls back to the active palette's first color.

[Parameter]
public string? Color { get; set; }

Property Value

string

ShowQuantileLines

When true, draws vertical guide lines at the median and 95th percentile of Values. Default false.

[Parameter]
public bool ShowQuantileLines { get; set; }

Property Value

bool

Values

Raw observations to bin and plot. Repeated values increase a bin's count.

[Parameter]
public IEnumerable<T>? Values { get; set; }

Property Value

IEnumerable<T>

XAxis

Configuration for the horizontal axis.

[Parameter]
public BOBChartAxis XAxis { get; set; }

Property Value

BOBChartAxis

YAxis

Configuration for the vertical axis.

[Parameter]
public BOBChartAxis YAxis { get; set; }

Property Value

BOBChartAxis

Methods

BuildAriaLabel()

Default ARIA label for the chart's <svg> root. Subclasses override to inject series / value summaries (improves screen-reader experience).

protected override string BuildAriaLabel()

Returns

string

RenderSvg(RenderTreeBuilder)

Concrete charts override this to emit SVG content. The supplied builder is positioned inside the <svg> root, so implementations only need to add geometry primitives (lines, paths, rects, text). Sequence numbers must remain unique within the override.

protected override void RenderSvg(RenderTreeBuilder builder)

Parameters

builder RenderTreeBuilder

Render tree builder positioned inside the SVG root.
