Properties

OnStepClick

Fired when the user clicks a funnel row.

[Parameter]
public EventCallback<BOBChartFunnelStep<TY>> OnStepClick { get; set; }

Property Value

EventCallback<BOBChartFunnelStep<TY>>

RowGap

Pixel gap between consecutive rows. Default 2.

[Parameter]
public double RowGap { get; set; }

Property Value

double

ShowValues

Show the per-step value (and optional drop-off %) inside each row. Default true.

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

Property Value

bool

Steps

Funnel stages, in top-to-bottom order.

[Parameter]
public IEnumerable<BOBChartFunnelStep<TY>>? Steps { get; set; }

Property Value

IEnumerable<BOBChartFunnelStep<TY>>

Tapered

When true (default) the rows render as trapezoids that taper down (classic funnel). Set to false for a horizontal-bar look with rectangular rows.

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

Property Value

bool

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.
