Serial plotter over bluetooth

It’s enough but I’d like to have the old line not cleared all at once time but disappearing once the new line is approching it. How could I manage it?

Examples of fading:

Moving On Curves / Examples

Simple Particle System / Examples

There may be others…

Slimmed down (to just a line) version of fading I use:

int i;
int alpha;

public void setup() 
  {
  size(512, 200);   
  background(0);
  }

public void draw() 
  {   
  background(0);
  
  i = 300; 
   
  for(int j = 0; j<i; j++)
    {
    alpha = 0;
    if (j > i - 255)
    alpha = 255 - (i - j);  // tail fades away 
      
    stroke(0, 255, 0, alpha);
    strokeWeight(10);
    point(j, height/2); 
    }  
  }

I used the above for my scrolling ECG plot:
