最佳答案
我不确定你是如何在显示坐标中得到BBox的.用户与之交互的几乎所有内容都在数据坐标中(对我来说看起来像轴或数据坐标,而不是显示像素).以下内容应充分说明适用于BBox的转换：
from matplotlib import pyplot as pltbars = plt.bar([1,2,3],[3,4,5])ax = plt.gca()fig = plt.gcf()b = bars[0].get_bBox() # bBox instanceprint b# Box in data coords#BBox(array([[ 1.,0. ],# [ 1.8,3. ]]))b2 = b.transformed(ax.transData)print b2# Box in display coords#BBox(array([[ 80.,48. ],# [ 212.26666667,278.4 ]]))print b2.transformed(ax.transData.inverted())# Box back in data coords#BBox(array([[ 1.,3. ]]))print b2.transformed(ax.transAxes.inverted())# Box in axes coordinates#BBox(array([[ 0.,0. ],# [ 0.26666667,0.6 ]]))
