Question

我创建了一个图表栏，我希望根据值的名称更改栏颜色。它有两个系列，一个显示绿色值，绿色值应为绿色，另一个为黄色。我还创建了一个css文件，但第一个问题是css中-fx-bar-fill的get unknown属性错误。除了我不知道如何在创建系列后调用适当的颜色？我当时面对这个警告：

我在这里创建图表

public class MostComputerizedController {
    @FXML
    private BarChart<String, Number> barChart;
    @FXML
    private CategoryAxis orgNameAxis;
    @FXML
    private NumberAxis yAxis;

    private ObservableList<String> orgNames = FXCollections
            .observableArrayList();

    private DataConstructor dc = new DataConstructor();

    @FXML
    private void initialize() {

        orgNames.addAll(dc.getSortedAssignedOrg().values());
        orgNameAxis.setCategories(orgNames);
        orgNameAxis.setLabel("Name of Organizations");
        orgNameAxis.tickLabelFontProperty().set(Font.font(10));
        yAxis.setLabel("Saturation");
        orgNameAxis.getStylesheets().add(
                getClass().getResource("/application/application.css").toExternalForm());

    }

    /*
     * *
     * Sets the organization to show the statistics for.
     * 
     * @param
     */
    public void setPersonData() {

        XYChart.Series<String, Number> series = new XYChart.Series<>();
        XYChart.Series<String, Number> seriesy = new XYChart.Series<>();
        series.setName("Green");
        seriesy.setName("Yellow");

        for (String entryOrg : dc.getSortedAssignedOrg().values()) {
            for (List<String> entryfuncType : dc.getFuncTypeOrg().values()) {
                if (entryOrg.equals(entryfuncType.get(5))
                        && entryfuncType.contains("hasType")) {

                    int yellow = Collections.frequency(entryfuncType, "yellow");
                    int green = Collections.frequency(entryfuncType, "Green");
                    int typeNumber = Collections.frequency(entryfuncType,
                            "hasType");

                    series.getData().add(
                            new XYChart.Data<String, Number>(entryOrg, green));
                    seriesy.getData().add(
                            new XYChart.Data<String, Number>(entryOrg, yellow));


                }
            }

        }

        barChart.getData().addAll(series,seriesy);
    }
}

主要是我把它添加到舞台：

public class Main extends Application {
    private Stage primaryStage;
    private BorderPane rootLayout;
    private Model model = new Model();

    @Override
    public void start(Stage primaryStage) {

        this.primaryStage = primaryStage;
        this.primaryStage.setTitle("IT-Saturation");
        initRootLayout();
        showOverView();

    }

    private void showOverView() {
        try {
            FXMLLoader loader = new FXMLLoader();

            loader.setLocation(Main.class.getResource("/view/OverView.fxml"));
            loader.setController(new OverViewController(model));

            AnchorPane overView = (AnchorPane) loader.load();
            rootLayout.setCenter(overView);

        } catch (IOException e) {
            e.printStackTrace();
        }
    }

    private void initRootLayout() {
        try {
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(Main.class.getResource("/view/RootLayout.fxml"));
            loader.setController(new RootLayoutController(model));

            rootLayout = (BorderPane) loader.load();
            // show scene containing the root layout
            Scene scene = new Scene(rootLayout);
            scene.getStylesheets().add(
                    getClass().getResource("application.css").toExternalForm());
            primaryStage.setScene(scene);
            RootLayoutController controller = loader.getController();
            controller.setMainApp(this);
            primaryStage.show();

        } catch (IOException e) {

            e.printStackTrace();
        }

    public void showMostComputerizedStatistics() {
        try {
            // Load the fxml file and create a new stage for the popup.
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(Main.class
                    .getResource("/view/MostComputerized.fxml"));
            AnchorPane page = (AnchorPane) loader.load();
            Stage dialogStage = new Stage();

            dialogStage.setTitle("Saturation in Organizations");
            dialogStage.initModality(Modality.WINDOW_MODAL);
            dialogStage.initOwner(primaryStage);
            Scene scene = new Scene(page);
            dialogStage.setScene(scene);
            dialogStage.getScene().getStylesheets().add(
                    getClass().getResource("chart.css").toExternalForm());
            MostComputerizedController controller = loader.getController();
            controller.setPersonData();
            dialogStage.show();

        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

这是css文件：

@CHARSET "UTF-8";

.default-color0.chart-bar {
-fx-bar-fill: green;
}

.default-color1.chart-bar {
-fx-bar-fill: yellow;
}

Answer 1

如果可以使用-fx-background-color而不是

来消除css警告

.default-color0.chart-bar { -fx-background-color: rgb(146,208,80); }

如何在Javafx中使用css作为图表栏颜色
