Plotting some variables in python

4 sets of (x,y) variables to plot. Just increment the numbers! Well, let's change the colors of the lines as well. Oh and we meant to plot the absolute values of course.

Input

def Plot_All():
    plt.plot(x1,y1,color='k',lw=0.8,label="line #1")
    plt.plot(x1,y1,color='k',lw=0.8,label="line #1")
    plt.plot(x1,y1,color='k',lw=0.8,label="line #1")
    plt.plot(x1,y1,color='k',lw=0.8,label="line #1")

Output

def Plot_All():
    plt.plot(x1,abs(y1),color='k',lw=0.8,label="line #1")
    plt.plot(x2,abs(y2),color='b',lw=0.8,label="line #2")
    plt.plot(x3,abs(y3),color='r',lw=0.8,label="line #3")
    plt.plot(x4,abs(y4),color='g',lw=0.8,label="line #4")
