mplfinance 是否有對數刻度設置？

Question

這是我用來用 mplfinance 繪制股票價格圖表的代碼，我希望圖表能夠對數縮放。 我怎樣才能做到這一點？

import mplfinance as mpf

# Data reading and processing steps omitted

mpf.plot(data, type='line')

Answer 1

這是我想出的解決方案：

import mplfinance as mpf
from matplotlib import pyplot as plt

# Data reading and processing steps omitted

fig, axlist = mpf.plot(data, type='line', returnfig=True)
ax = axlist[0]
ax.set_yscale('log')
plt.show()

Answer 2

@JakeBoggs 工作，但隨后文本格式是科學記數法。 對於正在研究此問題的任何其他人，我建議使用 ScalarFormatter 將軸轉換回

import mplfinance as mpf
from matplotlib import pyplot as plt
from matplotlib.ticker import ScalarFormatter

# Data reading and processing steps omitted

fig, axlist = mpf.plot(data, type='line', returnfig=True)
ax = axlist[0]
ax.set_yscale("log")
ax.yaxis.set_major_formatter(ScalarFormatter())
ax.yaxis.set_minor_formatter(ScalarFormatter())
plt.show()
