t-c-plotter's Introduction

T C Plotter

Tcp plotter in language c.

To build and run

setup_glfw.bat
build_msvc.bat
main.exe

Why

To live stream data from somewhere to plot it.

The good

It's faster than anything else.
It's easyer to implement client for in any language e.g.:

public class TcpPlotter : IDisposable {
  public TcpPlotter() {
    _tcpClient = new TcpClient();
    _writeThread = new Thread(SendingProc);
    _writeThread.Start();
  }
  public void Plot(double d) {
    _q.Enqueue(d);
  }
  public void Dispose() {
    shouldStop = true;
    _tcpClient.Close();
    _tcpClient.Dispose();
    _writeThread.Join();
  }
  private async void SendingProc() {
    while (!shouldStop) {
      try {
        _tcpClient.Connect(new System.Net.IPEndPoint(System.Net.IPAddress.Loopback, 42069));
        while (!shouldStop) {
          if (_q.Count > 0) {
            var val = _q.Dequeue();
            var bytes = System.Text.Encoding.UTF8.GetBytes($"{val} ");
            await _tcpClient.GetStream().WriteAsync(bytes);
          }
          else {
            await Task.Delay(50);
          }
        }
      }
      catch (Exception Ex) {
        await Task.Delay(50);
      }
    }
  }
  private readonly TcpClient _tcpClient;
  private readonly Thread _writeThread;
  private readonly Queue<double> _q = new Queue<double>();
  private bool shouldStop = false;
}

python client most likely shorter.
You can zoom in and out infinitly ( more or less )
You can pan by pressing right mouse button and dragging

The bad

Hardcoded port number ( No need for changing it! )
Bad documentation
More or less 0 actions ( no hover over line, no different scales, no menu of any kind, no nothing... )
Bad arhitecture ( more or less )
