To set a limit on the y-axis (i.e. the range), use the y-lim(~) method:
        
        
            
                
                
                    plt.plot([1,2,3])plt.ylim(0,4)plt.show()
                
            
            
        
    The output is as follows:
        Notice how the y-axis goes from 0 to 4, as specified.
Alternatively you can use the set_ylim(~) method:
        
        
            
                
                
                    fig, ax = plt.subplots()ax.set_ylim(0,4)
                
            
            
        
    Which produces the output:
