用于绘制数据的轻量级 Java 库。示例代码： ```java double[] xData = new double[] { 0.0, 1.0, 2.0 }; double[] yData = new double[] { 2.0, 1.0, 0.0 }; // Create Chart XYChart chart = QuickChart.getChart("Sample Chart", "X", "Y", "y(x)", xData, yData); // Show it new SwingWrapper(chart).displayChart(); // Save it BitmapEncoder.saveBitmap(chart, "./Sample_Chart", BitmapFormat.PNG); // or save it in high-res BitmapEncoder.saveBitmapWithDPI(chart, "./Sample_Chart_300_DPI", BitmapFormat.PNG, 300); ```
