用 javafx 繪製圖表的工具
- 圓餅圖 PieChart 無需軸
- 折線圖 LineChart<X,Y> 通常 CategoryAxis/NumberAxis
- 面積圖 AreaChart<X,Y> 同折線圖
- 長條圖 BarChart<X,Y> 通常 CategoryAxis/NumberAxis
- 氣泡圖 BubbleChart<Number,Number> 用第三值表示半徑
- 散點圖 ScatterChart<Number,Number> 點陣圖
- 累積面積圖 StackedAreaChart<X,Y> 多組堆疊數據區域
- 累積長條圖 StackedBarChart<X,Y> 長條堆疊比較
