I have this image:

plt.plot(sim_1[\'t\'],sim_1[\'V\'],\'k\')
plt.ylabel(\'V\')
plt.xlabel(\'t\')
plt.show()

I want to hide the numbers

    Without a subplots, you can universally remove the ticks like this:

    plt.xticks([])
    plt.yticks([])

    This works great. Just paste this before plt.show():

    plt.gca().axes.get_yaxis().set_visible(False)
    

    Boom.

    If you use the matplotlib object-oriented approach, this is a simple task using ax.set_xticklabels() and ax.set_yticklabels():

    import matplotlib.pyplot as plt
    
    # Create Figure and Axes instances
    fig,ax = plt.subplots(1)
    
    # Make your plot, set your axes labels
    ax.plot(sim_1['t'],sim_1['V'],'k')
    ax.set_ylabel('V')
    ax.set_xlabel('t')
    
    # Turn off tick labels
    ax.set_yticklabels([])
    ax.set_xticklabels([])
    
    plt.show()

    Not sure this is the best way, but you can certainly replace the tick labels like this:

    import matplotlib.pyplot as plt
    x = range(10)
    y = range(10)
    plt.plot(x,y)
    plt.xticks(x," ")
    plt.show()
    

    In Python 3.4 this generates a simple line plot with no tick labels on the x-axis. A simple example is here: http://matplotlib.org/examples/ticks_and_spines/ticklabels_demo_rotation.html

    This related question also has some better suggestions: Hiding axis text in matplotlib plots

    I'm new to python. Your mileage may vary in earlier versions. Maybe others can help?

    plt.gca().axes.yaxis.set_ticklabels([])

    to remove tickmarks entirely use:

    ax.set_yticks([])
    ax.set_xticks([])
    

    otherwise ax.set_yticklabels([]) and ax.set_xticklabels([]) will keep tickmarks.
