今天分享如何產生PieChart和LineChart In Java FX，javafx.scene.chart底下有好幾種chart，而且都很美觀，但工作上只用到剛剛說的兩種，產生相關Chart只要有FXCollection的基本觀念以及用過Excel的同好們，這個技巧應該不難，PieChart Data來源必須是PieChart.Data(ObservableList)物件，LineChart Data來源必須是XYChart.Series<K, V>，範例如下:

Note:細部的設定還是需要查詢API相關函數

import javafx.application.Application;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.geometry.Side;
import javafx.scene.Scene;
import javafx.scene.chart.CategoryAxis;
import javafx.scene.chart.LineChart;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.PieChart;
import javafx.scene.chart.XYChart;
import javafx.scene.chart.XYChart.Series;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
