Ich würde gerne wissen, warum Mein Diagramm nach meinen Einstellungen keine neuen Einstellungen erhält, wird die Achse nicht aktualisiert.Warum Liniendiagramm keine neuen Einstellungen erhält
Hauptklasse:
package sample;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root, 1200, 800));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Controller-Klasse; nach auf Übernehmen-Taste u die Variablen festlegen können, die u auf Achse X und Y haben wollen, auch einige Validierungen verwenden,
package sample;
import javafx.beans.binding.Bindings;
import javafx.event.ActionEvent;
import javafx.fxml.FXML;
import javafx.geometry.Side;
import javafx.scene.chart.LineChart;
import javafx.scene.chart.NumberAxis;
import javafx.scene.control.TextField;
public class Controller {
@FXML
private TextField xMin, xMax, yMin, yMax, xTick, yTick, width, height;
@FXML
private LineChart<Number, Number> axesTest;
@FXML
private NumberAxis xAxis, yAxis;
private Axes axes;
public void applyButtonClicked(ActionEvent event) {
System.out.println("Applyed...");
axes = new Axes();
axes.setxMin(Double.parseDouble(xMin.getText()));
axes.setxMax(Double.parseDouble(xMax.getText()));
axes.setyMin(Double.parseDouble(yMin.getText()));
axes.setyMax(Double.parseDouble(yMax.getText()));
axes.setxTickUnit(Double.parseDouble(xTick.getText()));
axes.setyTickUnit(Double.parseDouble(yTick.getText()));
axes.setAxesWidth(Integer.parseInt(width.getText()));
axes.setAxesHeight(Integer.parseInt(height.getText()));
xAxis = new NumberAxis(axes.getxMin(), axes.getxMax(), axes.getxTickUnit());
xAxis.setSide(Side.BOTTOM);
xAxis.setMinorTickVisible(false);
xAxis.setPrefWidth(axes.getAxesWidth());
xAxis.setLayoutY(axes.getAxesHeight()/2);
xAxis.autosize();
xAxis.setLowerBound(axes.getxMin());
xAxis.setUpperBound(axes.getxMax());
xAxis.setTickUnit(axes.getxTickUnit());
yAxis = new NumberAxis(axes.getyMin(), axes.getyMax(), axes.getyTickUnit());
yAxis.setSide(Side.LEFT);
yAxis.setMinorTickVisible(false);
yAxis.setPrefHeight(axes.getAxesHeight());
yAxis.layoutXProperty().bind(Bindings.subtract((axes.getAxesWidth()/2) + 1, yAxis.widthProperty()));
yAxis.setLowerBound(axes.getyMin());
yAxis.setUpperBound(axes.getyMax());
yAxis.setTickUnit(axes.getyTickUnit());
axesTest = new LineChart<Number, Number>(xAxis, yAxis);
// System.out.println("xMin : " + axes.getxMin() + "xMax : " + axes.getxMax() + "yMin :" + axes.getyMin() + "yMax : " + axes.getyMax()
// + "xTick : " + axes.getxTickUnit() + "yTick : " + axes.getyTickUnit());
}
public void startButtonClicked() {
}
}
Achsen-Klasse ist für jede Variable Einstellung, die ich auf meine Achsen haben wollen.
package sample;
import javafx.scene.chart.NumberAxis;
import javafx.scene.layout.Pane;
public class Axes extends Pane {
private NumberAxis xAxis;
private NumberAxis yAxis;
private double xMin, xMax, yMin, yMax, xTickUnit, yTickUnit;
private int axesWidth, axesHeight;
public Axes() {
this.xMin = 0;
this.xMax = 0;
this.yMin = 0;
this.yMax = 0;
this.xTickUnit = 0;
this.yTickUnit = 0;
this.axesWidth = 0;
this.axesHeight = 0;
}
public NumberAxis getXAxis() {
return xAxis;
}
public NumberAxis getYAxis() {
return yAxis;
}
public int getAxesWidth() {
return axesWidth;
}
public void setAxesWidth(int axesWidth) {
this.axesWidth = axesWidth;
}
public int getAxesHeight() {
return axesHeight;
}
public void setAxesHeight(int axesHeight) {
this.axesHeight = axesHeight;
}
public double getxMin() {
return xMin;
}
public void setxMin(double xMin) {
this.xMin = xMin;
}
public double getxMax() {
return xMax;
}
public void setxMax(double xMax) {
this.xMax = xMax;
}
public double getyMin() {
return yMin;
}
public void setyMin(double yMin) {
this.yMin = yMin;
}
public double getyMax() {
return yMax;
}
public void setyMax(double yMax) {
this.yMax = yMax;
}
public double getxTickUnit() {
return xTickUnit;
}
public void setxTickUnit(double xTickUnit) {
this.xTickUnit = xTickUnit;
}
public double getyTickUnit() {
return yTickUnit;
}
public void setyTickUnit(double yTickUnit) {
this.yTickUnit = yTickUnit;
}
}

Im Mittelpunkt des Grenzbereich sollte für die Startanwendung Standard Achse sein und nach auf die Schaltfläche Anwenden der Achse zeigte sollte klicken, die ich will. Es aktualisiert es nicht, also meine Frage ist: Was ich falsch mache? Oder was fehlt mir im Code? Vielen Dank.
