UltrachartRenderer

UltrachartRenderer

internal UltrachartRenderer(UltrachartSurface ultraChartSurface)

ultrachartRenderer = UltrachartRenderer(ultraChartSurface)

初始化了 & ##UltrachartRenderer+# 类的新实例 。

ultraChartSurface

The parent UltrachartSurface

OnDrawAnnotations

internal static void OnDrawAnnotations(UltrachartSurface scs, RenderPassInfo rpi)

UltrachartRenderer.OnDrawAnnotations(scs, rpi)

步骤5,绘制说明

OnDrawAxes

internal static void OnDrawAxes(IUltrachartSurface scs, RenderPassInfo rpi, IRenderContext2D renderContext)

UltrachartRenderer.OnDrawAxes(scs, rpi, renderContext)

第3步, 绘制轴

OnDrawSeries

internal static void OnDrawSeries(IUltrachartSurface scs, RenderPassInfo rpi, IRenderContext2D renderContext)

UltrachartRenderer.OnDrawSeries(scs, rpi, renderContext)

第4步, 绘图序列

OnLayoutUltrachart

internal Size OnLayoutUltrachart(IUltrachartSurface scs)

result = ultrachartRenderer.OnLayoutUltrachart(scs)

步骤 1, 执行布局, 调整组件大小

scs

PrepareRenderData

internal static RenderPassInfo PrepareRenderData(IUltrachartSurface scs, Size viewportSize)

result = UltrachartRenderer.PrepareRenderData(scs, viewportSize)

步骤2,准备提供数据

RenderLoop

public RendererErrorCode RenderLoop(IRenderContext2D renderContext)

result = ultrachartRenderer.RenderLoop(renderContext)

执行一次渲染传出

TryPerformAutorangeOn

internal void TryPerformAutorangeOn(IAxis axis, IUltrachartSurface parentSurface)

ultrachartRenderer.TryPerformAutorangeOn(axis, parentSurface)

/ 设置一个默认范围, 如果不存在的话, 在布局前
