mplfinance 是否有对数刻度设置？

Question

这是我用来使用 mplfinance 绘制股票价格图表的代码，我希望图表按对数比例缩放。我怎样才能做到这一点？

import mplfinance as mpf

# Data reading and processing steps omitted

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

Answer 1

这是我想出的解决方案：

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 有效，但文本格式是科学记数法。对于任何正在研究这个的人，我建议使用 ScalarFormatter

将轴转换回来

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()
