根因分析
在定位器仍为自动定位器时调用 set_xticklabels() 并使用 FixedFormatter,导致标签与刻度位置不匹配。
English
Calling set_xticklabels() with a FixedFormatter while the locator is still an auto locator, causing labels to be mismatched with tick positions.
解决方案
-
95% 成功率
import numpy as np ax.set_xticks(np.arange(len(labels))) ax.set_xticklabels(labels, rotation=45, ha='right')
-
90% 成功率
from matplotlib.ticker import FuncFormatter ax.xaxis.set_major_formatter(FuncFormatter(lambda x, pos: labels[int(x)] if 0 <= int(x) < len(labels) else ''))
无效尝试
常见但无效的做法:
-
70% 失败
Labels may still be placed at wrong positions, producing a misleading plot.
-
85% 失败
The mismatch remains; the warning is informational about the locator/formatter pair.
