Graph plotting C# - c#

I am working on an interface in C#, which reads data from the serial port and displays it on a graph. I wrote the following code, but the graph doesn't display anything. What is wrong? I don't know exactly what should I modify.

this.chart1.ChartAreas[0].AxisX.Minimum = 0;

}
private void Connect_button_Click(object sender, EventArgs e)

if (serialPort1.IsOpen)
{

Communication between 2 Form in C#(Keep connecting from Fom1 for Form2) [duplicate]

Original close reason(s) were not resolved
I am a newbie in C# and I have questions as below:
I have a Form1 name is setting Port Name, Baud Rate, Parity... of modbus protocol and I can open serial Port.
Also, I have another Form is called Form2, When Port is opened i want to close Form1 and Port alway Open => I can do it. But this problem that was I want to get data such as FC03 HolodingRegister, FC01 WriteSingleCoil... for Form2 but didnot.
I used delegate to transfer data from Form 1 to Form 2 but I could not use button Form2 to send FC01 signal.
How to use FC01, FC03,04... for Form2 when Form 1 connected.

When I understand you right, you will in Form1 open a connection, close the Form, open a new Form2 and use this connection there?
Well, when that's the case, you could make an special Connection Singleton to hold this connection then you can use it in your Form2
using System;
namespace Sandbox
{
public sealed class Connection
{
private static readonly Lazy<Connection> _instance = new Lazy<Connection>(() => new Connection());
public static Connection Instance => _instance.Value;
private Connection()
{ }
// Implement your Connection Code here.
}
}

How to receive and send data from Serial Ports in Visual Studio(Using C#)

I am trying to set up a serial com interface that will send and receive data in the Windows Forms App with C#. I can confirm that I am sending and receiving data from the ports with the help of a virtual serial port driver app since it also shows the number of bytes sent and received. However, the text box doesn't display the received messages. There no reported errors.

UIRobot controller and program in C#

I have this a controller from UIRobot. Here is manual: enter link description here
I want to write software to controle it in C#.
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO.Ports;
namespace hhh
{
class Program
{
static void Main(string[] args)
{
string ot = "Port je otvoreny";
string za = "Port je zavrety";
string COM = "COM1";
string command = "ENABLE";
SerialPort sp = new SerialPort(COM, 9600);
sp.Open();
if (sp.IsOpen)
{
Console.WriteLine(ot);
sp.Write(command);
sp.ReadLine();
}
else
{
sp.Write(za);
}
Console.ReadKey();
}
}
}
In manual is command ENABLE to initialize controller but it does not work in my code. How Can I send command or where I do a mistake?
I have learned something new so here is update my code and new question.
I want to recieve position of motor. There is command "POS;" which has to give me the value but I get message box with question mark (?) instead number value. Why?

}

{
sp.Write("OFFLINE;");
sp.Close();

disable.Enabled = false;

}
}
private void zero_Click(object sender, EventArgs e)
{
sp.Write("POS0; SPD400;");
}
private void increase_Click(object sender, EventArgs e)
{
sp.Write("STP1000; SPD400;");
}
private void inc10_Click(object sender, EventArgs e)
{
sp.Write("STP10; SPD400;");
}
private void decrease_Click(object sender, EventArgs e)
{
sp.Write("STP-1000; SPD400;");
}
private void dec10_Click(object sender, EventArgs e)
{
sp.Write("STP10; SPD400;");
}
private void close_Click(object sender, EventArgs e)
{
if (sp.IsOpen)
{
sp.Write("OFFLINE;");
sp.Close();
}
Application.Exit();
}
private void fbk_Click(object sender, EventArgs e)
{
sp.Write("POS;");
string msg = sp.ReadExisting();
MessageBox.Show(msg);
}
}
}

According to that document, the command is "ENABLE;" You have to include the semicolon. So change your code to:
string command = "ENABLE;";
