Removing previously plotted points on scatter plot; python

[Morbidly_Green]

Homework Statement

I'm plotting moving particles and I need a way to refresh the graph space with every loop. Meaning I want the points to NOT leave a trail of other points behind them . Basically I want to get rid of the old points as I plot new ones.

Homework Equations

N\A

The Attempt at a Solution

The code for plotting that is being used :

while True:

    plt.ion()
    plt.show()

    x,y = 0,0

    for i in range(n_particles):
        x = particle_pos[i,0]
        y = particle_pos[i,1]
        plt.scatter(x,y, color='green')
        plt.pause(0.001)
        plt.xlim(0 , L)
        plt.ylim(0 , L)

Try matplotlib in jupyter, it is meant for this task, assuming I got what you need. You need to consider timing (refresh rates) as well. Otherwise the points will appear only for milliseconds before erasure.
