how to smooth a function in python
x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.8
def smooth(y, box_pts):
box = np.ones(box_pts)/box_pts
y_smooth = np.convolve(y, box, mode='same')
return y_smooth
plot(x, y,'o')
plot(x, smooth(y,3), 'r-', lw=2)
plot(x, smooth(y,19), 'g-', lw=2)how to form smooth curve in matplotlib

#create data
x = np.array([1, 2, 3, 4, 5, 6, 7, 8])
y = np.array([4, 9, 12, 30, 45, 88, 140, 230])
#define x as 200 equally spaced values between the min and max of original x
xnew = np.linspace(x.min(), x.max(), 200)
#define spline
spl = make_interp_spline(x, y, k=3)
y_smooth = spl(xnew)
#create smooth line chart
plt.plot(xnew, y_smooth)
