>>> import transix as tx
>>> import matplotlib.pyplot as plt
>>> from matplotlib.ticker import FuncFormatter
>>>
>>> t = tx.time(duration=120, fs=10000)
>>> y = tx.generate_sine(mag=1, f=1, t=120, fs=10000)
>>> fig, ax = plt.subplots()
>>> ax.plot(t, y)
>>> ax.xaxis.set_major_formatter(FuncFormatter(tx.fmt_mmss))
>>> plt.show()
