Java 3d 图表 JavaGnuplotHybrid

Question

我想用 java 编写 3D 图表软件。我找到了类似 gnuplot 和 JavaGnuplotHybrid 的东西以及这个例子:

JGnuplot jg = new JGnuplot();
Plot plot0 = new Plot("2d plot") {
    String xlabel = "'x'", ylabel = "'y'";
};
double[] x = { 1, 2, 3, 4, 5 }, y1 = { 2, 4, 6, 8, 10 }, y2 = { 3, 6, 9, 12, 15 };
DataTableSet dts = plot0.addNewDataTableSet("Simple plot");
dts.addNewDataTable("2x", x, y1);
dts.addNewDataTable("3x", x, y2);
jg.execute(plot0, jg.plot2d);

代码有效并显示图表。我不知道如何开始 3D 图表，如果有人可以在 3D 图表上写出这样一个漂亮的简单的单点示例？

Answer 1

以下是示例 3d 图表的代码:

public void plot3d() {
    JGnuplot jg = new JGnuplot();
    Plot plot = new Plot("") {
        {
            xlabel = "x";
            ylabel = "y";
            zlabel = "z";
        }
    };
    double[] x = { 1, 2, 3, 4, 5 }, y = { 2, 4, 6, 8, 10 }, z = { 3, 6, 9, 12, 15 }, z2 = { 2, 8, 18, 32, 50 };
    DataTableSet dts = plot.addNewDataTableSet("3D Plot");
    dts.addNewDataTable("z=x+y", x, y, z);
    dts.addNewDataTable("z=x*y", x, y, z2);
    jg.execute(plot, jg.plot3d);
}

它产生下图:
