public static class ChartCanvasHelper

Helper methods for easily rendering charts to a Unity Canvas. Swift Charts-style simplicity for programmatic chart creation.

Usage:

// Render to full canvas
var chart = Chart.Create(data, item => new BarMark(
    PlottableValue.Value("Category", item.Name),
    PlottableValue.Value("Value", item.Amount)
)).Build();

ChartCanvasHelper.RenderToCanvas(chart, canvas);

// Or with specific position and size
ChartCanvasHelper.RenderToCanvas(chart, canvas, new Vector2(100, 100), new Vector2(400, 300));

Methods

RenderToCanvas(Chart, Canvas, string)

public static ChartGraphic RenderToCanvas(Chart chart, Canvas canvas, string name = "Chart")

Returns

ChartGuru.ChartGraphic — The ChartGraphic component for further customization.

RenderToCanvas(Chart, Canvas, Vector2, Vector2, string)

public static ChartGraphic RenderToCanvas(Chart chart, Canvas canvas, Vector2 position, Vector2 size, string name = "Chart")

Renders a chart at a specific position and size within the canvas.

Parameters

Name	Type	Description
chart	ChartGuru.Chart	The chart to render.
canvas	UnityEngine.Canvas	The target canvas.

Returns

ChartGuru.ChartGraphic — The ChartGraphic component for further customization.

RenderMiniChart(Chart, RectTransform, Vector2, string)

public static ChartGraphic RenderMiniChart(Chart chart, RectTransform parent, Vector2 size, string name = "MiniChart")
