Excessive use of pens C # [closed]

Good morning, friends,

I'm developing an application that should draw 4 graphics (for now), to draw the way you want it to need to redraw the graphics several times and update them. With too much drawline, performance drops. When I stop drawing, all my app runs normal, but when it starts to draw everything goes slow until it stops completely (including the buttons). Please, does anyone know a way to optimize this code? Any tips? Thank you very much!! Below are the main parts of the code.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    //metodo que chama o controle que desenha o gráfico---------------------------------------
    private void SerialCOM_DataReceived(object sender, System.IO.Ports.SerialDataReceivedEventArgs e)
    {
        if (SerialCOM.IsOpen)
        {
            SerialPort sData = (SerialPort)sender;
            {
                string RxString = sData.ReadLine();
                bool result = int.TryParse(RxString, out int data);
                if (result)
                {
                    var atualdata = 5.0f * data / 1023.0f;

                    //CHAMADA DO CONTROLE
                    graphControl1.AddValue(atualdata, atualdata, atualdata, atualdata);

                    if (controlegravar == 1 && aquisicaodata.Count <= 6000) aquisicaodata.Add(atualdata);
                }
            }
        }
    }
}

Detail: The datareceived method is called by a timer with an interval of 3 ms. It needs to be very fast.
