Homework Help: Removing previously plotted points on scatter plot; python

  1. Nov 12, 2017 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations
    N\A

    3. The attempt at a solution
    The code for plotting that is being used :
    Code (Python):

    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)
     
    Mentor edit - added code tags.
