Question

我有一个机器人在空间输出x，y，z位置。我的问题是我只能使用图表在Windows窗体中找到2D图。

我想在3D空间中绘制我的机器人。我可以用的任何工具吗？

我的2D图表atm：

        chart1.ChartAreas[0].AxisX.Minimum = 0;
        chart1.ChartAreas[0].AxisX.Maximum = 12;
        chart1.ChartAreas[0].AxisX.Interval = 1;

        chart1.ChartAreas[0].AxisY.Minimum = 0;
        chart1.ChartAreas[0].AxisY.Maximum = 7;
        chart1.ChartAreas[0].AxisY.Interval = 1;

        //example
        posicao_atual_master.X = 10;
        posicao_atual_master.Y = 5;




         chart1.Series[0].Points.Clear();
        chart1.Series[0].Points.AddXY(posicao_atual_master.X, posicao_atual_master.Y);

你是对的，没有正确的方法在Chart控件中使用真正的z轴。

它确实有3D风格，可用于相当不错的ChartArea。

你必须在代码中绘制图形，因为内置的z轴只支持与图表中Series一样多的，或者更少的离散值。

对于某些事情，例如彩色立方体，这是可以的，但是当你需要仲裁数据值时，它就不会这样做。

相反，你可以这样做：

将每个DataPoint的z值与Y值存储在YValues数组中。
为此，您需要一个支持多个YValues的ChartType
编写其中一个xxxPaint事件以绘制图形
为此，您需要从值到像素的转换

首先我们准备图表。许多细节都符合您的需求;

void prepare3dChart(Chart chart, ChartArea ca)
{
    ca.Area3DStyle.Enable3D = true;  // set the chartarea to 3D!
    ca.AxisX.Minimum = -250;
    ca.AxisY.Minimum = -250;
    ca.AxisX.Maximum = 250;
    ca.AxisY.Maximum = 250;
    ca.AxisX.Interval = 50;
    ca.AxisY.Interval = 50;
    ca.AxisX.Title = "X-Achse";
    ca.AxisY.Title = "Y-Achse";
    ca.AxisX.MajorGrid.Interval = 250;
    ca.AxisY.MajorGrid.Interval = 250;
    ca.AxisX.MinorGrid.Enabled = true;
    ca.AxisY.MinorGrid.Enabled = true;
    ca.AxisX.MinorGrid.Interval = 50;
    ca.AxisY.MinorGrid.Interval = 50;
    ca.AxisX.MinorGrid.LineColor = Color.LightSlateGray;
    ca.AxisY.MinorGrid.LineColor = Color.LightSlateGray;

    // we add two series:
    chart.Series.Clear();
    for (int i = 0; i < 2; i++)
    {
        Series s = chart.Series.Add("S" + i.ToString("00"));
        s.ChartType = SeriesChartType.Bubble;   // this ChartType has a YValue array
        s.MarkerStyle = MarkerStyle.Circle;
        s["PixelPointWidth"] = "100";
        s["PixelPointGapDepth"] = "1";
    }
    chart.ApplyPaletteColors();

    addTestData(chart);
}

这里我们添加一些测试数据：

void addTestData(Chart chart)
{
    Random rnd = new Random(9);
    for (int i = 0; i < 100; i++)
    {
        double x = Math.Cos(i/10f )*88 + rnd.Next(5);
        double y = Math.Sin(i/11f)*88 + rnd.Next(5);
        double z = Math.Sqrt(i*2f)*88 + rnd.Next(5);

        AddXY3d( chart.Series[0], x, y, z);
        AddXY3d( chart.Series[1], x-111, y-222, z);
    }
}

DataPoints添加了此例程：

int AddXY3d(Series s, double xVal, double yVal, double zVal)
{
    int p = s.Points.AddXY(xVal, yVal, zVal);
    // the DataPoint are transparent to the regular chart drawing:
    s.Points[p].Color = Color.Transparent;
    return p;
}

如果这个Paint事件我们按照自己喜欢的方式绘制数据。这是行或点：

private void chart1_PostPaint(object sender, ChartPaintEventArgs e)
{
    Chart chart = sender as Chart;

    if (chart .Series.Count < 1) return;
    if (chart .Series[0].Points.Count < 1) return;

    ChartArea ca = chart .ChartAreas[0];
    e.ChartGraphics.Graphics.SmoothingMode = SmoothingMode.AntiAlias;

    List<List<PointF>> data = new List<List<PointF>>();
    foreach (Series s in chart .Series)
        data.Add(GetPointsFrom3D(ca, s, s.Points.ToList(), e.ChartGraphics));

    renderLines(data, e.ChartGraphics.Graphics, chart , true);  // pick one!
    renderPoints(data, e.ChartGraphics.Graphics, chart , 6);   // pick one!
}

使用轴方法计算坐标：

List<PointF> GetPointsFrom3D(ChartArea ca, Series s, 
                             List<DataPoint> dPoints, ChartGraphics cg)
{
    var p3t = dPoints.Select(x => new Point3D((float)ca.AxisX.ValueToPosition(x.XValue),
        (float)ca.AxisY.ValueToPosition(x.YValues[0]),
        (float)ca.AxisY.ValueToPosition(x.YValues[1]))).ToArray();
    ca.TransformPoints(p3t.ToArray());

    return p3t.Select(x => cg.GetAbsolutePoint(new PointF(x.X, x.Y))).ToList();
}

实际绘图发生在这些例程中;一个画出其他点的线条：

void renderLines(List<List<PointF>> data, Graphics graphics, Chart chart, bool curves)
{
    for (int i = 0; i < chart.Series.Count; i++)
    {
      if (data[i].Count > 1)
         using (Pen pen = new Pen(Color.FromArgb(64, chart.Series[i].Color), 2.5f))
            if (curves) graphics.DrawCurve(pen, data[i].ToArray());
            else graphics.DrawLines(pen, data[i].ToArray());
    }
}

void renderPoints(List<List<PointF>> data, Graphics graphics, Chart chart, float width)
{
    for (int s = 0; s < chart.Series.Count; s++)
    {
        Series S = chart.Series[s];
        for (int p = 0; p < S.Points.Count; p++)
            using (SolidBrush brush = new SolidBrush(Color.FromArgb(64, S.Color)))
                graphics.FillEllipse(brush, data[s][p].X-width/2, 
                                     data[s][p].Y-width/2,width, width);
    }
}

其他绘图例程（如网格或区域）也可以编码。只需使用用户GDI +方法（如DrawCurve或FillPolygon或甚至DrawImage）添加新例程。

您可以为不同的视图设置ChartArea.Area3DStyle.Rotation和ChartArea.Area3DStyle.Inclination，如动画中所示。

修改我更新了PostPaint方法，以尽量减少依赖关系。
