      Description

      Look at the attached movie.

      You may see, how I set gap to negative value and chart starts to be affected by such value.

      Code:


      import java.util.Arrays;
      import java.util.Comparator;
      import java.util.Random;
      import javafx.application.Application;
      import javafx.collections.FXCollections;
      import javafx.collections.ObservableList;
      import javafx.scene.Scene;
      import javafx.scene.chart.LineChart;
      import javafx.scene.chart.NumberAxis;
      import javafx.scene.chart.XYChart;
      import javafx.scene.control.Slider;
      import javafx.scene.layout.Pane;
      import javafx.scene.layout.VBox;
      import javafx.stage.Stage;

      public class JavaCharts extends Application {

          public static void main(String[] args) {
              launch(args);
          }
          NumberAxis axis1 = new NumberAxis(0, 100, 10);
          NumberAxis axis2 = new NumberAxis(0, 100, 10);
          LineChart testedLineChart = new LineChart(axis1, axis2);
          VBox vb = new VBox();

          @Override
          public void start(Stage stage) throws Exception {
              testedLineChart.setTitle("LineChart");
              testedLineChart.setStyle("-fx-border-color: darkgray;");

              ObservableList list = FXCollections.observableArrayList();
              int max = 100;
              int min = 30;

              for (int i = 0; i < 30; i++) {
                  XYChart.Data newData = new XYChart.Data();
                  newData.setXValue(new Random().nextDouble() * (max - min) + min);
                  newData.setYValue(new Random().nextDouble() * (max - min) + min);
                  list.add(newData);
              }
              Object[] array = list.toArray();
              Arrays.sort(array, new Comparator() {

                  @Override
                  public int compare(Object t, Object t1) {
                      return (int) Math.round(((Double) ((XYChart.Data) t).getXValue()) - ((Double) ((XYChart.Data) t1).getXValue()));
                  }
              });

              XYChart.Series serie = new XYChart.Series("serie", FXCollections.observableArrayList(array));

              testedLineChart.getData().add(serie);

              axis2.setTickMarkVisible(false);
              axis2.setMinorTickVisible(false);

              Pane pane = new Pane();
              pane.setPrefSize(600, 600);

              Slider slider = new Slider(-100, 100, 10);
              slider.setPrefWidth(500);
              slider.valueProperty().bindBidirectional(axis2.tickLabelGapProperty());
              slider.setShowTickLabels(true);
              slider.setShowTickMarks(true);

              pane.setPrefSize(600, 600);
              pane.getChildren().add(testedLineChart);

              vb.getChildren().addAll(pane, slider);

              Scene scene = new Scene(vb, 700, 700);
              stage.setScene(scene);
              stage.show();
          }
      }

      Just move slider.
