I'd use matplotlib.

This is straightforward in most plotting packages. Here's a simple
example of doing it in matplotlib:
#!/usr/bin/env python3
import matplotlib.pyplot as plt
times = [0, 1, 2, 3, 4, 5] # hours
temperatures = [68, 70, 75, 73, 72, 71] # Fahrenheit
fig = plt.figure(figsize=(5, 4))
ax = fig.add_axes([0.15, 0.15, 0.70, 0.70])
ax.plot(times, temperatures)
ax.set_xlabel('Time (hours)')
ax.set_ylabel(r'Temp ($^{\circ}\mathrm{F}$)')
ax.set_title('Temperature vs time')
plt.show()
