Pandas : histogram with fixed width
提问by MatthieuBizien
I have data which I want to do an histogram, but I want the histogram to start from a given value and the width of a bar to be fixed. For example, for the serie [1, 3, 5, 10, 12, 20, 21, 25], I want, instead of
我有我想做直方图的数据，但我希望直方图从给定的值开始，条形的宽度是固定的。例如，对于系列 [1, 3, 5, 10, 12, 20, 21, 25]，我想要，而不是
>>> p.Series([1, 3, 5, 10, 12, 20, 21, 25]).hist(bins=3).figure
# | |
# | | |
# | | |
# 0 8.5 17
I want the bars to have a width of 10 :
我希望条形的宽度为 10 ：
| |
| | |
| | |
0 10 20
How can I do that ?
我怎样才能做到这一点 ？

I think
我认为
p.Series([1, 3, 5, 10, 12, 20, 21, 25]).hist(bins=[0, 10, 20, 30]).figure
will do what you want. Alternately you can do
会做你想做的。或者你可以做
p.Series([1, 3, 5, 10, 12, 20, 21, 25]).hist(bins=3, range=(0,30)).figure
See documentationfor histand the documentationfor np.histogram.
I suspect you are also running into some issues because it is labeling the centerof the bins, not the edges.
我怀疑您也遇到了一些问题，因为它标记的是垃圾箱的中心，而不是边缘。
