Charts JavaFX我想完全保存图表图像

这是我的代码：

public class SceneToImageAndWrite extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        stage.setTitle("Primary Stage");

        final CategoryAxis xAxis = new CategoryAxis();
        xAxis.setLabel("Animals");
        final NumberAxis yAxis = new NumberAxis();
        yAxis.setLabel("Number");

        final LineChart<String, Number> lineChart = new LineChart<String, Number>(xAxis, yAxis);
        lineChart.setTitle("Line Chart");

        XYChart.Series<String, Number> series1 = new Series<String, Number>();
        series1.setName("Series");

        /** xAxis & yAxis Data */
        LinkedHashMap<String, Number> map = new LinkedHashMap<>();      
        map.put("dog", 12);
        map.put("cat", 3);
        map.put("bear", 8);
        map.put("tiger", 20);

        for (Entry<String, Number> entry : map.entrySet()) {
            series1.getData().add(new XYChart.Data<String, Number>(entry.getKey(), entry.getValue()));
        }

        lineChart.getData().add(series1);

        Scene scene = new Scene(lineChart);
        stage.setScene(scene);
        stage.show();

        WritableImage snapShot = scene.snapshot(null);
        ImageIO.write(SwingFXUtils.fromFXImage(snapShot, null), "png", new File("test.png"));
    }
}

公共类SceneToImageAndWrite扩展了应用程序{
公共静态void main（字符串[]args）{
发射（args）；
}
@凌驾
public void start（Stage）引发异常{
阶段。片名（“初级阶段”）；
最终CategoryAxis xAxis=新CategoryAxis（）；
xAxis.setLabel（“动物”）；
最终数字axis yAxis=新数字axis（）；
yAxis.setLabel（“编号”）；
最终线形图线形图=新线形图（xAxis，yAxis）；
线形图。设置标题（“线形图”）；
XYChart.Series系列1=新系列（）；
系列1.集合名称（“系列”）；
/**xAxis和yAxis数据*/
LinkedHashMap=新建LinkedHashMap（）；
地图.put（“狗”，12）；
地图放置（“cat”，3）；
地图放置（“熊”，8）；
地图.put("老虎",20);；
for（条目：map.entrySet（））{
series1.getData（）.add（新的XYChart.Data（entry.getKey（），entry.getValue（））；
}
lineChart.getData（）.add（series1）；
场景=新场景（折线图）；
舞台场景；
stage.show（）；
WritableImage snapShot=scene.snapShot（空）；
write（SwingFXUtils.fromFXImage（快照，null），“png”，新文件（“test.png”）；
}
}

框架很好，但保存的图像并没有它应该拥有的所有图表数据。 我想完全保存图表图像，怎么了？⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

在图表上关闭

public class SceneToImageAndWrite extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        stage.setTitle("Primary Stage");

        final CategoryAxis xAxis = new CategoryAxis();
        xAxis.setLabel("Animals");
        final NumberAxis yAxis = new NumberAxis();
        yAxis.setLabel("Number");

        final LineChart<String, Number> lineChart = new LineChart<String, Number>(xAxis, yAxis);
        lineChart.setTitle("Line Chart");

        XYChart.Series<String, Number> series1 = new Series<String, Number>();
        series1.setName("Series");

        /** xAxis & yAxis Data */
        LinkedHashMap<String, Number> map = new LinkedHashMap<>();      
        map.put("dog", 12);
        map.put("cat", 3);
        map.put("bear", 8);
        map.put("tiger", 20);

        for (Entry<String, Number> entry : map.entrySet()) {
            series1.getData().add(new XYChart.Data<String, Number>(entry.getKey(), entry.getValue()));
        }

        lineChart.getData().add(series1);

        Scene scene = new Scene(lineChart);
        stage.setScene(scene);
        stage.show();

        WritableImage snapShot = scene.snapshot(null);
        ImageIO.write(SwingFXUtils.fromFXImage(snapShot, null), "png", new File("test.png"));
    }
}

从javadoc：

public class SceneToImageAndWrite extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        stage.setTitle("Primary Stage");

        final CategoryAxis xAxis = new CategoryAxis();
        xAxis.setLabel("Animals");
        final NumberAxis yAxis = new NumberAxis();
        yAxis.setLabel("Number");

        final LineChart<String, Number> lineChart = new LineChart<String, Number>(xAxis, yAxis);
        lineChart.setTitle("Line Chart");

        XYChart.Series<String, Number> series1 = new Series<String, Number>();
        series1.setName("Series");

        /** xAxis & yAxis Data */
        LinkedHashMap<String, Number> map = new LinkedHashMap<>();      
        map.put("dog", 12);
        map.put("cat", 3);
        map.put("bear", 8);
        map.put("tiger", 20);

        for (Entry<String, Number> entry : map.entrySet()) {
            series1.getData().add(new XYChart.Data<String, Number>(entry.getKey(), entry.getValue()));
        }

        lineChart.getData().add(series1);

        Scene scene = new Scene(lineChart);
        stage.setScene(scene);
        stage.show();

        WritableImage snapShot = scene.snapshot(null);
        ImageIO.write(SwingFXUtils.fromFXImage(snapShot, null), "png", new File("test.png"));
    }
}

当通过应用程序显式或隐式（如图表动画）拍摄正在设置动画的场景的快照时，快照将基于拍摄快照时场景图的状态进行渲染，并且不会反映任何后续动画更改

public class SceneToImageAndWrite extends Application {

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) throws Exception {
        stage.setTitle("Primary Stage");

        final CategoryAxis xAxis = new CategoryAxis();
        xAxis.setLabel("Animals");
        final NumberAxis yAxis = new NumberAxis();
        yAxis.setLabel("Number");

        final LineChart<String, Number> lineChart = new LineChart<String, Number>(xAxis, yAxis);
        lineChart.setTitle("Line Chart");

        XYChart.Series<String, Number> series1 = new Series<String, Number>();
        series1.setName("Series");

        /** xAxis & yAxis Data */
        LinkedHashMap<String, Number> map = new LinkedHashMap<>();      
        map.put("dog", 12);
        map.put("cat", 3);
        map.put("bear", 8);
        map.put("tiger", 20);

        for (Entry<String, Number> entry : map.entrySet()) {
            series1.getData().add(new XYChart.Data<String, Number>(entry.getKey(), entry.getValue()));
        }

        lineChart.getData().add(series1);

        Scene scene = new Scene(lineChart);
        stage.setScene(scene);
        stage.show();

        WritableImage snapShot = scene.snapshot(null);
        ImageIO.write(SwingFXUtils.fromFXImage(snapShot, null), "png", new File("test.png"));
    }
}

非常感谢你。线形图。设置动画（假）；
