c# - OxyPlot:使用 OxyPlot 和 WindowsForms 在一个窗口上绘制多个图形

Question

我一直在将 OxyPlot 用于我目前正在进行的项目之一，并且效果非常好。但是，我一直无法解决在一个窗口中绘制多个图形的问题。我的目标是能够做类似 this 的事情.

我当前的单图看起来像 this .

这是我的一些代码

        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

我想要做的是对几个不同的数据数组使用相同的“创建线性系列 -> 填充 -> 绘图”方法，并如前所述显示它。我正在为此项目使用 WindowsForms 和 OxyPlot。

Answer 1

这是我使用 bgura 的推荐所做的。

我首先创建了多个 PlotView 并设置了它们的属性。我改变了它们的大小，这样它们就不会占据整个窗口，并且我确保注释掉“Dock”属性设置为填充的那一行，因为这导致大小的变化没有效果。然后，您可以调整窗体和各个 PlotView 的大小，以实现多绘图效果。

    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);

    }

然后我创建了多个 PlotModel 并用数据填充它们，并将它们分配给相应的 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;

希望这可以帮助需要实现相同功能的人。如果有人想知道，我几乎使用了 OxyPlot 文档中的 HelloWorld 程序并将其添加到其中。那可以查到here
