OxyPlot：使用 OxyPlot 和 WindowsForms 在一個窗口上繪制多個圖形

Question

我一直在將 OxyPlot 用於我目前正在進行的項目之一，並且效果很好。 但是，我一直無法解決在一個窗口中繪制多個圖形的問題。 我的目標是能夠做到像這樣。

我目前的單一情節是這樣的。

這是我的一些代碼

        var myModel = new PlotModel { Title = "REBA Score" };

        myModel.Axes.Add(new LinearAxis { Position = AxisPosition.Bottom, MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Minimum = 0, Maximum = a_count, Title = "Frame" });
        myModel.Axes.Add(new LinearAxis { Position = AxisPosition.Left, MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Minimum = 0, Maximum = 15, Title = "Score" });



        var series1 = new LineSeries
        {
            StrokeThickness = 1,
            MarkerSize = 1,
        };

        for (int i = 0; i < a_count; i++)
        {
            int x_val = i;
            int y_val = scores[0, i]; //"scores" is an array with my data

            series1.Points.Add(new DataPoint(x_val, y_val));

        }

        myModel.Series.Add(series1);


        this.plot1.Model = myModel //plot1 is an object of PlotView

我想要做的是對幾個不同的數據數組使用相同的“創建線性系列 -> 填充 -> 繪圖”方法，並使其顯示如前面提到的那樣。 我在這個項目中使用 WindowsForms 和 OxyPlot。

Answer 1

這是我使用 bgura 的推薦所做的。

我首先創建了多個 PlotView 並設置了它們的屬性。 我改變了它們的大小，這樣它們就不會占據整個窗口，並且我確保注釋掉“Dock”屬性設置為填充的行，因為這會導致大小的變化不起作用。 然后，您可以調整 Form 和單個 PlotView 的大小以實現多圖效果。

    private OxyPlot.WindowsForms.PlotView plot1;
    private OxyPlot.WindowsForms.PlotView plot2;
    private OxyPlot.WindowsForms.PlotView plot3;


         private void InitializeComponent()
    {
        this.plot1 = new OxyPlot.WindowsForms.PlotView();
        this.plot2 = new OxyPlot.WindowsForms.PlotView();
        this.plot3 = new OxyPlot.WindowsForms.PlotView();
        this.SuspendLayout();
        // 
        // plot1
        // 
        //this.plot1.Dock = System.Windows.Forms.DockStyle.Fill;
        this.plot1.Location = new System.Drawing.Point(0, 0);
        this.plot1.Name = "plot1";
        this.plot1.PanCursor = System.Windows.Forms.Cursors.Hand;
        this.plot1.Size = new System.Drawing.Size(300, 300);
        this.plot1.TabIndex = 0;
        this.plot1.Text = "plot1";
        this.plot1.ZoomHorizontalCursor = System.Windows.Forms.Cursors.SizeWE;
        this.plot1.ZoomRectangleCursor = System.Windows.Forms.Cursors.SizeNWSE;
        this.plot1.ZoomVerticalCursor = System.Windows.Forms.Cursors.SizeNS;
        // 
        // plot2
        // 
        //this.plot2.Dock = System.Windows.Forms.DockStyle.Fill;
        this.plot2.Location = new System.Drawing.Point(300, 0);
        this.plot2.Name = "plot2";
        this.plot2.PanCursor = System.Windows.Forms.Cursors.Hand;
        this.plot2.Size = new System.Drawing.Size(300, 300);
        this.plot2.TabIndex = 0;
        this.plot2.Text = "plot2";
        this.plot2.ZoomHorizontalCursor = System.Windows.Forms.Cursors.SizeWE;
        this.plot2.ZoomRectangleCursor = System.Windows.Forms.Cursors.SizeNWSE;
        this.plot2.ZoomVerticalCursor = System.Windows.Forms.Cursors.SizeNS;
        // 
        // plot3
        // 
        //this.plot3.Dock = System.Windows.Forms.DockStyle.Fill;
        this.plot3.Location = new System.Drawing.Point(900, 600 );
        this.plot3.Name = "plot3";
        this.plot3.PanCursor = System.Windows.Forms.Cursors.Hand;
        this.plot3.Size = new System.Drawing.Size(300,300);
        this.plot3.TabIndex = 0;
        this.plot3.Text = "plot3";
        this.plot3.ZoomHorizontalCursor = System.Windows.Forms.Cursors.SizeWE;
        this.plot3.ZoomRectangleCursor = System.Windows.Forms.Cursors.SizeNWSE;
        this.plot3.ZoomVerticalCursor = System.Windows.Forms.Cursors.SizeNS;
        // 
        // Form1
        // 
        this.AutoScaleDimensions = new System.Drawing.SizeF(6F, 13F);
        this.AutoScaleMode = System.Windows.Forms.AutoScaleMode.Font;
        this.ClientSize = new System.Drawing.Size(1225, 900);
        this.Controls.Add(this.plot3);
        this.Controls.Add(this.plot1);
        this.Controls.Add(this.plot2);
        this.Name = "Form1";
        this.Text = "plot3 Score";
        this.ResumeLayout(false);

    }

然后我創建了多個 PlotModel 並用數據填充它們，並將它們分配給相應的 PlotView：

        this.InitializeComponent();

        //Setup plot1
        var plot1_model = new PlotModel { Title = "plot1 Score" };

        plot1_model.Axes.Add(new LinearAxis { Position = AxisPosition.Bottom, MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Minimum = 0, Maximum = a_count, Title = "Frame" });
        plot1_model.Axes.Add(new LinearAxis { Position = AxisPosition.Left, MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Minimum = 0, Maximum = 15, Title = "Score" });


        var plot1_Series = new LineSeries { StrokeThickness = 1, MarkerSize = 1 };

        for (int i = 0; i < a_count; i++)
        {
            int x_val = i;
            int y_val = your_data[0, i];

            plot1_Series.Points.Add(new DataPoint(x_val, y_val));

        }

        plot1_model.Series.Add(plot1_Series);

        //Setup plot2
        var plot2_Model = new PlotModel { Title = "plot2 Score" };

        plot2_Model.Axes.Add(new LinearAxis { Position = AxisPosition.Bottom, MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Minimum = 0, Maximum = a_count, Title = "Frame" });
        plot2_Model.Axes.Add(new LinearAxis { Position = AxisPosition.Left, MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Minimum = 0, Maximum = 15, Title = "Score" });


        var plot2_Series = new LineSeries { StrokeThickness = 1, MarkerSize = 1 };

        for (int i = 0; i < a_count; i++)
        {
            int x_val = i;
            int y_val = your_data[1, i];

            plot2_Series.Points.Add(new DataPoint(x_val, y_val));

        }

        plot2_Model.Series.Add(plot2_Series);







        //Setup plot3
        var plot3_Model = new PlotModel { Title = "plot3 Score" };

        plot3_Model.Axes.Add(new LinearAxis { Position = AxisPosition.Bottom, MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Minimum = 0, Maximum = a_count, Title = "Frame" });
        plot3_Model.Axes.Add(new LinearAxis { Position = AxisPosition.Left, MajorGridlineStyle = LineStyle.Solid, MinorGridlineStyle = LineStyle.Dot, Minimum = 0, Maximum = 15, Title = "Score" });


        var plot3_Series = new LineSeries{ StrokeThickness = 1, MarkerSize = 1};

        for (int i = 0; i < a_count; i++)
        {
            int x_val = i;
            int y_val = your_data[3, i];

            plot3_Series.Points.Add(new DataPoint(x_val, y_val));

        }
        this.plot1.Model = plot1_Model;
        this.plot2.Model = plot2_model;
        this.plot3.Model = plot3_Model;

希望這可以幫助需要實現相同功能的人。 如果有人想知道，我幾乎使用了 OxyPlot 文檔中的 HelloWorld 程序並將其添加到其中。 可以在這里找到

Answer 2

我使用TableLayoutPanel在不同的行和列中排列單獨的圖。 我計划以編程方式添加圖形，以便我可以添加行並將它們停靠在布局中。

Answer 3

當我遇到同樣的問題時，我想建議我對此主題的解決方案。 如果您想在一個 Plotview 中繪制多個圖形（具有不同的比例），您不需要每次都創建一個新的 Plotview。 只需為要添加新圖形的軸分配一個“AxisKey”。

例如：這些是軸：

Dim xAxes As New OxyPlot.Axes.DateTimeAxis()
With xAxes
    .Key = "x_first_Time"
    .Position = Axes.AxisPosition.Bottom
    .StringFormat = "HH:mm:ss"
    .Unit = "ms"
    .Title = "Zeitintervall"
    .TitleFont = "Arial"
    .TitleFontSize = 18.0!
    .TitleFontWeight = FontWeights.Bold
    .MajorGridlineStyle = LineStyle.Dot
    .MajorGridlineThickness = 0.5

End With
model.Axes.Add(xAxes)

Dim yAxestemp As New OxyPlot.Axes.LinearAxis()
With yAxestemp
    .Position = Axes.AxisPosition.Left
    .Unit = "deg Celsius"
    .Key = "y_first_Temp"
    .TitlePosition = 0.5
    .AxisTitleDistance = 10
    .Title = "Temperatur "
    .TitleFont = "Arial"
    .TitleFontSize = 18.0!
    .TitleFontWeight = FontWeights.Bold
    .MajorGridlineStyle = LineStyle.Dot
    .MajorGridlineThickness = 0.5

End With
model.Axes.Add(yAxestemp)

Dim yAxesRPM As New OxyPlot.Axes.LinearAxis()
With yAxesRPM
    .Position = Axes.AxisPosition.Right
    .Unit = "1/min"
    .Key = "y_second_RPM"
    .TitlePosition = 0.5
    .AxisTitleDistance = 10
    .Title = "Drehzahl "
    .TitleFont = "Arial"
    .TitleFontSize = 18.0!
    .TitleFontWeight = FontWeights.Bold

End With
model.Axes.Add(yAxesRPM)
Plot.Model = model

系列看起來像這樣：

With Sensor1series
    .Title = "Sensor_1"
    .YAxisKey = "y_first_Temp"
End With
model.Series.Add(Sensor1series)

With Sensor2series
    .Title = "Sensor_2"
    .YAxisKey = "y_first_Temp"
End With
model.Series.Add(Sensor2series)

With Sensor3series
    .Title = "Sensor_3"
    .YAxisKey = "y_first_Temp"
End With
model.Series.Add(Sensor3series)

With Sensor4series
    .Title = "Sensor_4"
    .YAxisKey = "y_first_Temp"
End With
model.Series.Add(Sensor4series)

With drehzahlseries
    .Title = "Drehzahl [rpm]"
    .LineStyle = LineStyle.Dot
    .YAxisKey = "y_second_RPM"
End With
model.Series.Add(drehzahlseries)

為了用一些數據填充這些系列，我在另一個類中創建了一個包含數據的列表。 這是填充系列的示例：

Sensor1series.Points.Add(New OxyPlot.DataPoint(Time, Datalist.Last.tempvalue1))
Sensor2series.Points.Add(New OxyPlot.DataPoint(Time, Datalist.Last.tempvalue2))
Sensor3series.Points.Add(New OxyPlot.DataPoint(Time, Datalist.Last.tempvalue3))
Sensor4series.Points.Add(New OxyPlot.DataPoint(Time, Datalist.Last.tempvalue4))
drehzahlseries.Points.Add(New OxyPlot.DataPoint(Time, Datalist.Last.RPM))
TextBox_Time.Text = Datalist.Last.time.ToString()

這應該是這樣的，Rpm 位於輔助軸上。
