JavaFX Stacked Area Chart

Introduction

The JavaFX stacked area chart is a visualization tool that is used to display the composition of multiple data series over time or any other continuous domain. It is an extension of the area chart where multiple data sets are stacked on top of each other.

Features

• Data Visualization: Using stacked area charts, programmers can represent the distribution of different data series over a continuous domain, such as time.
• Stacking: The chart stacks the individual data series on top of each other, allowing easy comparison of their relative contributions to the overall composition.
• Customizable: Programmers can customize various elements of the chart, such as colors, axis labels, tool tips, legend, etc.
• Interactive: Users can interact with the chart by hovering over the areas to view data values, clicking on legend items to show/hide a particular series, and zooming in/out for a detailed analysis.

Code Example

The following code demonstrates how to create a basic stacked area chart in JavaFX using the StackedAreaChart class:

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.StackedAreaChart;
import javafx.scene.chart.XYChart;
import javafx.stage.Stage;

public class StackedAreaChartApp extends Application {

    @Override
    public void start(Stage stage) {
        // Create the X and Y axis
        NumberAxis xAxis = new NumberAxis();
        NumberAxis yAxis = new NumberAxis();

        // Create the stacked area chart
        StackedAreaChart<Number, Number> areaChart = new StackedAreaChart<>(xAxis, yAxis);

        // Add data series to the chart
        XYChart.Series<Number, Number> series1 = new XYChart.Series<>();
        series1.getData().add(new XYChart.Data<>(1, 50));
        series1.getData().add(new XYChart.Data<>(2, 75));
        // Add more data points to series1

        XYChart.Series<Number, Number> series2 = new XYChart.Series<>();
        series2.getData().add(new XYChart.Data<>(1, 30));
        series2.getData().add(new XYChart.Data<>(2, 40));
        // Add more data points to series2

        // Add series to the chart
        areaChart.getData().addAll(series1, series2);

        // Create and set the scene
        Scene scene = new Scene(areaChart, 800, 600);
        stage.setScene(scene);
        stage.setTitle("Stacked Area Chart Example");
        stage.show();
    }

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

Conclusion

The JavaFX stacked area chart is a powerful tool for visually representing the composition of multiple data series in a continuous domain. With its customizable features and interactive capabilities, programmers can create informative and visually appealing charts for data analysis and presentation.
