Here is my function: def JerkFunction(listOfJerk): '''Return the plot of a sequence of jerk''' #initialization of the jerk x = np.linspace(0,5,4) y = listOfJerk #step signal plt.axis([0,5,-2,2]) plt.step(x,y,'y') #step display plt.xlabel('Time (s)') plt.ylabel('Jerk (m/s^3)') plt.title('Jerk produced by the engine') return plt.show() I would like to have the curve obtained when I put JerkFunction([1,1,-1,1]) but by entering: [1,-1,1,-1] , indeed,
