Draw Surface Chart via Java

The open source Jzy3d library gives software developers the capability to draw surface charts using Java commands. First of all, you need to define the range for the function to plot the chart. After that, you can create the object to represent the function over the given range. Now you can easily draw charts. You draw a simple surface, big surface, Delaunay tesselation, no wireframe surface, and more.

import org.jzy3d.chart.Chart;
import org.jzy3d.chart.factories.AWTChartComponentFactory;
import org.jzy3d.colors.Color;
import org.jzy3d.maths.Range;
import org.jzy3d.plot3d.builder.Mapper;
import org.jzy3d.plot3d.builder.SurfaceBuilder;
import org.jzy3d.plot3d.primitives.Shape;

public class SurfaceChartExample {

    public static void main(String[] args) {
        // Define the function to be plotted
        Mapper mapper = new Mapper() {
            @Override
            public double f(double x, double y) {
                return Math.sin(x) * Math.cos(y);
            }
        };

        // Define the range of the plot
        Range range = new Range(-Math.PI, Math.PI);

        // Build the surface
        SurfaceBuilder surfaceBuilder = new SurfaceBuilder();
        Shape surface = surfaceBuilder.buildOrthonormal(new OrthonormalGrid(range, 50, range, 50), mapper);

        // Set surface color
        surface.setColor(Color.GREEN);

        // Create a chart
        Chart chart = AWTChartComponentFactory.chart();

        // Add the surface to the chart
        chart.getScene().getGraph().add(surface);

        // Show the chart
        chart.open("Surface Chart Example");
    }
}
 

Create 3D Polar Charts

The Jzy3d library gives software programmers the power to create 3D Polar Charts with ease inside their apps. You can need to set the values for the chart as a dedicated polar dataset allows you to easily make operations on the coordinates. You can define the chart title, the dataset for the chart, chart legend, tooltips, and URLs.

import org.jzy3d.chart.Chart;
import org.jzy3d.chart.factories.AWTChartComponentFactory;
import org.jzy3d.colors.Color;
import org.jzy3d.maths.Range;
import org.jzy3d.plot3d.builder.Mapper;
import org.jzy3d.plot3d.builder.SurfaceBuilder;
import org.jzy3d.plot3d.primitives.Shape;

public class SurfaceChartExample {

    public static void main(String[] args) {
        // Define the function to be plotted
        Mapper mapper = new Mapper() {
            @Override
            public double f(double x, double y) {
                return Math.sin(x) * Math.cos(y);
            }
        };

        // Define the range of the plot
        Range range = new Range(-Math.PI, Math.PI);

        // Build the surface
        SurfaceBuilder surfaceBuilder = new SurfaceBuilder();
        Shape surface = surfaceBuilder.buildOrthonormal(new OrthonormalGrid(range, 50, range, 50), mapper);

        // Set surface color
        surface.setColor(Color.GREEN);

        // Create a chart
        Chart chart = AWTChartComponentFactory.chart();

        // Add the surface to the chart
        chart.getScene().getGraph().add(surface);

        // Show the chart
        chart.open("Surface Chart Example");
    }
}
 

Build and Manage 3D Charts via Java

The open source Jzy3d library gives software developers the capability to build and manage 3D charts inside their application using Java commands. The Jzy3d Logarithm Toolbox can be very helpful in drawing 3d charts with log scales very easily. You can also easily edit your charts with ease. It provides dedicated axis, views, ordering strategies, and colormaps suitable for clean logarithmic charts with ease.

Edit Surface Mesh via Java

The Jzy3d library gives software developers the capability to edit their surface meshes via Java code. It has provided SDK that has provided interactive surface editor which enables users to model a surface by grabbing its mesh points with the mouse or trackpad. The surface is presented in an excel-like table that is synchronized with drawing.

import javax.swing.*;

public class Jzy3dSurfaceMeshExample {

    public static void main(String[] args) {
        // Define the surface function
        Mapper mapper = new Mapper() {
            @Override
            public double f(double x, double y) {
                return Math.sin(x) * Math.cos(y);
            }
        };

        // Define the range for x and y
        Range range = new Range(-Math.PI, Math.PI);

        // Create a surface mesh
        Surface surface = new Surface(mapper, range, 50, Color.RED);

        // Create a chart
        Chart chart = new Chart(Quality.Advanced);

        // Add the surface to the chart
        chart.getScene().getGraph().add(surface);

        // Create a frame for the chart
        JFrame frame = new JFrame("Jzy3d Surface Mesh Example");
        frame.setSize(800, 600);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        // Add the chart to the frame
        frame.getContentPane().add(chart.getCanvas());

        // Make the frame visible
        frame.setVisible(true);

        // Edit the surface function after a delay
        SwingUtilities.invokeLater(() -> {
            // Modify the surface function
            Mapper newMapper = new Mapper() {
                @Override
                public double f(double x, double y) {
                    return Math.sin(x) * Math.sin(y); // Modified function
                }
            };

            // Update the surface with the new function
            surface.setMapper(newMapper);
            chart.render();
        });
    }
}
