使用多索引控制数据帧子批次分组

Question

与：

seq   = range(1,10)
rep   = range(1,3)
names = ["marco", "marcee"]
cols  = {}

cols["time"]   = [aTime+x*aMinute for x in seq for y in names]
cols["person"] = [y for x in seq for y in names]
cols["points"] = [np.log(x+y) for x in seq for y in rep]
cols["fish"]   = [np.log2(x+y) for x in seq for y in rep]

multiTSDF = pd.DataFrame(data=cols).set_index(["time", "person"])
multiTSDF.unstack("person")

当调用plot()时，我得到一个绘图，x是时间，y是fish或points的值。如果我设置subplots=True，那么我得到四个图。如何获得两个绘图，一个是fish绘图，另一个是points绘图，其中每个绘图包含两个人各自的一行
