You may adapt the code from this answer to include a slider.

### using this class is as easy as using FuncAnimation:
fig, ax = plt.subplots()
x = np.linspace(0,6*np.pi, num=100)
y = np.sin(x)
ax.plot(x,y)
point, = ax.plot([],[], marker="o", color="crimson", ms=15)
def update(i):
point.set_data(x[i],y[i])
ani = Player(fig, update, maxi=len(y)-1)
plt.show()
