Example 1: matplotlib plot import matplotlib . pyplot as plt fig = plt . figure ( 1 ) #identifies the figure plt . title ( "Y vs X" , fontsize = '16' ) #title plt . plot ( [ 1 , 2 , 3 , 4 ] , [ 6 , 2 , 8 , 4 ] ) #plot the points plt . xlabel ( "X" , fontsize = '13' ) #adds a label in the x axis plt . ylabel ( "Y" , fontsize = '13' ) #adds a label in the y axis plt . legend ( ( 'YvsX' ) , loc = 'best' ) #creates a legend to identify the plot plt . savefig ( 'Y_X.png' ) #saves the figure in the present directory plt . grid ( ) #shows a grid under the plot plt . show ( ) Example 2: pyplot.plot plot ( [ x ] , y , [ fmt ] , * , data = None , * * kwargs ) plot ( [ x ] , y , [ fmt ] , [ x2 ] , y2 , [ fmt2 ] , . . . , * * kwargs )
