用法與介面

DemoWaterfall 以文字說明與具名資源列呈現示意性的請求順序,不包含實測時間軸或動畫播放。選用標記可指出首次繪製等條件,但也須在圖說中解釋該條件。實測結果應使用基準測試元件。

<DemoWaterfall  title="A dependency discovered later"  description="The second request becomes known after the first resource loads."  rows={[    { label: 'Entry', start: 0, end: 40, tone: 'violet' },    { label: 'Dependency', start: 50, end: 90, tone: 'blue' }  ]}/>

位置值介於 0 到 100,只表示繪圖幾何。請以文字說明相依關係;裝飾用長條對輔助科技隱藏。容器較窄時,標籤會堆疊在各軌道上方。請參閱關鍵資源。 瀑布圖檢視頁呈現目前的請求順序圖。
