Clustered Scatter Chart

使用 ZingChart 視覺化足球員行進的距離

在本教程中，我們將使用 ZingChart 建立散點圖，以視覺化不同足球比賽中球員的移動距離。這張圖表顯示了多場比賽的模擬數據，可以深入了解每分鐘所經過的距離。

程式碼說明

此程式碼片段使用 JavaScript 產生八個遊戲的虛假數據，然後使用 ZingChart 配置並渲染散佈圖。

遊戲資料：每個遊戲都表示為獨特的資料系列。
隨機距離：遊戲中每分鐘的距離都是隨機的，以模擬現實世界的分佈。
圖表配置： 圖表使用 ZingChart 的散佈圖類型、可自訂標記和軸進行設定。

以下是建立此圖表的完整 HTML 和 JavaScript 程式碼。
