我试图用二进制标记图形的 x 轴,而不是 Python 2.7 中的浮点值。我正在尝试FormatStrFormatter('%b')根据Python 软件基金会提供的文档使用它。我还希望所有二进制字符串的字符长度相同。我也咨询过这个链接。
我得到的错误是:
ValueError: 不支持的格式字符 'b' (0x62) 在索引 1
我试过这样做:
import matplotlib.pyplot as plt
import numpy as np
from matplotlib.ticker import FormatStrFormatter
fig, ax = plt.subplots()
ax.yaxis.set_major_formatter(FormatStrFormatter('%b'))
ax.yaxis.set_ticks(np.arange(0, 110, 10))
x = np.arange(1, 10, 0.1)
plt.plot(x, x**2)
plt.show()
