How matplotlib show obvious changes?

I hope this helps . I want to draw a pictrue with matplotlib. The y value is large,but the change of y is too small.For example,y = 1270000,but just has a change change range [-10,10].How could i show obvious changes of y?The pictrue could not show changes. enter image description here , I would go for something like this:

import numpy as np
import matplotlib.pylab as pl

x = np.arange(100)
y = np.random.randint(1270000-10, 1270000+10, x.size)

pl.figure()
pl.subplot(121)
pl.plot(x,y)
pl.ylim(y.min()-1, y.max()+1)

pl.subplot(122)
pl.plot(x,y)
pl.ylim(y.min()-1, y.max()+1)
ax=pl.gca()
ax.get_yaxis().get_major_formatter().set_useOffset(False)

will be helpful for those in need The answer, as pointed out by @ImportanceOfBeingErnest is that the backend configuration for me wasn't working. I'm not sure if I need to install some additional libraries or not. I decided not to use the MacOSX backend and used the Qt5Agg backend. This worked just fine and I didn't have to install any new libraries.

I think the issue was by ths following , I think the imshow documentation is pretty clear on that:

matplotlib:line chart to show all products price on each date with matplotlib or seaborn

Hope this helps how to use line chart to show all products price on each date in one chart? , Assuming your dataframe:

import pandas as pd

df = pd.DataFrame({'product':['pen','apple','book','cup','pen','apple','book','cup','pen','apple','book','cup',],
                   'price':[1,2,3,4,0.8,2.2,3.1,3.5,.6,2.6,2.1,4.3],
                   'date':['20190101','20190101','20190101','20190101','20190102','20190102','20190102','20190102','20190103','20190103','20190103','20190103']})

import matplotlib.pyplot as plt

for i in df.groupby('product'):
    plt.plot(i[1].date,i[1].price,'-o',label=i[0])

plt.legend(loc='upper center',
           bbox_to_anchor=(0.5, -0.2),
           fancybox=True,
           shadow=True,
           ncol=4)
plt.xlabel('date')
plt.ylabel('price')
plt.show()
