如何在C＃中绘制折线图， [英] How do I draw line chart in C#,

问题描述

namespace VistaBalanceAlgorithms
{
    public class VerticalForce
    {
        public static float SteadyStateTotalForce = 1;
        public static bool SteadyState = false;

        public VerticalForce(float[] frameValues)
        {
            Left = 0;
            Right = 0;
            Total = 0;

            if (frameValues != null)
            {
                float leftForce = frameValues.Take(frameValues.Length / 2).Sum();
                float rightForce = frameValues.Skip(frameValues.Length / 2).Sum();
                Left = (int)((leftForce / SteadyStateTotalForce) * 100);
                Right = (int)((rightForce / SteadyStateTotalForce) * 100);

                Left = Left < 0 ? 0 : Left;
                Right = Right < 0 ? 0 : Right;

                Total = Left + Right;
            }
        }

        public int Left { get; protected set; }
        public int Right { get; protected set; }
        public int Total { get; protected set; }
    }

    public class VerticalForceGraph
    {
        private List<VerticalForce> vtfList = new List<VerticalForce>();

        public int BufferSize { get; set; }

        public void Add(VerticalForce vtf)
        {
            vtfList.Add(vtf);
        }

        public void Reset() { vtfList.Clear(); }

        public int Count {get{return vtfList.Count;} }

        public float[] GetLeftVTF()
        {
            return vtfList.Select(x => (float)x.Left).ToArray();
        }

        public float[] GetLeftVTF(int startPoint, int count)
        {
            return vtfList.GetRange(startPoint, count).Select(x => (float)x.Left).ToArray();
        }

        public float[] GetRightVTF()
        {
            return vtfList.Select(x => (float)x.Right).ToArray();
        }

        public float[] GetRightVTF(int startPoint, int count)
        {
            return vtfList.GetRange(startPoint, count).Select(x => (float)x.Right).ToArray();
        }

        public float[] GetTotalVTF()
        {
            return vtfList.Select(x => (float)x.Total).ToArray();
        }

        public float[] GetTotalVTF(int startPoint, int count)
        {
            return vtfList.GetRange(startPoint, count).Select(x => (float)x.Total).ToArray();
        }
    }
}

我想调用这些方法并为每个绘制折线图



我尝试过的方法：



这是我的mainform.cs

I want to call these methods and draw line chart for each

What I have tried:

This is my mainform.cs

private void toolStripMenuItemVtfGraphicalView_Click(object sender, EventArgs e)
       {
           m_viewMode = viewModes.VTF_GRAPHICAL_VIEW;
           panelHeatMap.viewMode = m_viewMode;

           toolStripDropDownViewMode.Text = toolStripMenuItemVtfGraphicalView.Text;
           chart1.Visible = true;
           for (int i = 10; i < 100; i += 50)
           {
               chart1.Series["Left Vtf"].Points.AddXY(vtfGraph.GetLeftVTF(),i);
               chart1.Series["Right Vtf"].Points.AddXY(vtfGraph.GetRightVTF(),i);
               chart1.Series["Total Vtf"].Points.AddXY(vtfGraph.GetTotalVTF(),i);
           }


       }

推荐答案

MSDN提供了一个基本的使用System.Windows.Forms.DataVisualization.Charting的教程，以下链接引用Visual Studio 2012;

我在MVC网站中使用.Net Framework 4.5等价物它适用于我需要的东西



亲切的问候

MSDN provides a basic tutorials using System.Windows.Forms.DataVisualization.Charting, the below links refer to Visual Studio 2012;

I am using the .Net Framework 4.5 equivalent in an MVC site & it works for what I need
