根因分析

向set_xticklabels()等函数传递了旋转值列表，但该函数期望为所有标签设置一个标量值，或为标签列表配合标量旋转。

English

Passing a list of rotation values to set_xticklabels() or similar, which expects a single value for all labels or a list of labels with a scalar rotation.

generic

解决方案

  1. 95% 成功率 Use a scalar rotation value 
    ax.set_xticklabels(labels, rotation=45)
  2. 90% 成功率 Apply rotation individually using a loop 
    for label in ax.get_xticklabels(): label.set_rotation(45)

无效尝试

常见但无效的做法:

  1. Using a tuple instead of a list 80% 失败

    Tuples are also not accepted; rotation must be a scalar.

  2. Setting rotation via rcParams for all ticks 70% 失败

    This changes default but doesn't fix the TypeError from passing a list.
