代码：

from datetime import datetime
import numpy as np
from matplotlib.finance import date2num
from matplotlib import style
import matplotlib.pyplot as plt
from matplotlib.finance import candlestick_ohlc
import matplotlib.dates as md
import matplotlib.ticker as mticker

# Generar numpy.array con los 4 datos, convirtiendo la fecha en flotante para graficar
convertir = lambda x: date2num(datetime.strptime(x.decode("utf-8"), '%Y%m%d%H%M'))
fecha, apertura, alto, bajo, cierre = np.loadtxt('datos_tratados.csv', delimiter=',', unpack=True,
                                                 converters={0: convertir})


style.use('dark_background')
plt.rc('font', size=10)
figura, ax = plt.subplots()
plt.title('EURUSD', size=15)
plt.grid(False)

ohlc = []
for i in range(len(fecha)):
    agregar = fecha[i], apertura[i], alto[i], bajo[i], cierre[i]
    ohlc.append(agregar)

# Generar el gráfico ohlc y configuraciones básicas del eje x
#plt.plot(fecha, cierre)
candlestick_ohlc(ax, ohlc, width=0.0004, colorup='lime', colordown='red')
xfmt = md.DateFormatter('%d %b %H:%M')
ax.xaxis.set_major_formatter(xfmt)

for label in ax.xaxis.get_ticklabels():
    label.set_rotation(90)

# plt.xticks(fecha)
ax.xaxis.set_major_locator(mticker.MaxNLocator(25))
plt.xlim(min(fecha) - 0.001, max(fecha) + 0.0017)
ax.yaxis.tick_right()
plt.subplots_adjust(left=0.01, bottom=0.20, right=0.94, top=0.90, wspace=0.2, hspace=0)
plt.show()

我该怎么办？

使用matplotlib在y轴上放置正确的标签
