matplotlib - 直方图 bin 是左关闭还是右关闭？

Question

绘制直方图时，bin 是否包含小于和等于 bin 值的所有内容？

例如，如果我有一个介于 0 和 1 之间的 bin，该 bin 会包含大于 0 但小于或等于 1 的所有内容吗？

Answer 1

来自NumPy documentation :

All but the last (righthand-most) bin is half-open. In other words, if bins is:

[1, 2, 3, 4]

then the first bin is [1, 2) (including 1, but excluding 2) and the second [2, 3). The last bin, however, is [3, 4], which includes 4.
