How to modify the length of the tick marks in JavaFX XY charts?

JavaFXObject Oriented ProgrammingProgramming

The javafx.scene.XYChart class is the base class of all the charts that are plotted in an x-y pane. By instantiating the subclasses of this class you can create various XY charts namely − line chart, area chart, bar chart, pie chart, bubble chart, scatter chart, etc.

In the XY chart, the given data points are plotted on an XY plane. Along the x and y axes, you will have the tick marks and tick labels. The tick marks represent various values with uniform intervals.

Changing the length of the tick marks

The javafx.scene.chart.Axis class (abstract) is the base class of all the axes in XY charts. To create X and Y axes you need to instantiate subclasses of these classes

The NumberAxis class is used to create an axis for numerical values and the CategoryAxis class is used to create axis for string categories.

This class has a property named tick length (double), it specifies the length of all the tick lines in the current axis. You can set the value of this property using the setTickLength() method.

To change the length of the tick marks of an XY chart invoke this method bypassing the required length as a parameter.

      //Creating labels to the axes
      //Creating the Bubble chart
      BubbleChart bubbleChart = new BubbleChart(xAxis, yAxis);
      //Preparing data for bubble chart
      XYChart.Series series = new XYChart.Series();
      series.getData().add(new XYChart.Data(10, 30, 4));
      series.getData().add(new XYChart.Data(25, 40, 5));
      series.getData().add(new XYChart.Data(40, 50, 6));
      series.getData().add(new XYChart.Data(55, 60, 8));
      series.getData().add(new XYChart.Data(70, 70, 9));
      //series.getData().add(new XYChart.Data(85, 80, 12));
      //Setting the data to bar chart
      //Setting name to the bubble chart
      //Changing the length of the tickmark
      //Creating a stack pane to hold the chart
      StackPane pane = new StackPane(bubbleChart);
      pane.setPadding(new Insets(15, 15, 15, 15));
      pane.setStyle("-fx-background-color: BEIGE");
      //Setting the Scene
      Scene scene = new Scene(pane, 595, 350);
