histplot: cumulative in reverse order

[FWin22]

Hi,

would it be possible to allow cumulative to take a value of "-1" to enable the cumulative distribution to be calculated in reverse order. similar to the matplotlib.hist function (https://matplotlib.org/stable/api/_as_gen/matplotlib.pyplot.hist.html).

That's a pretty hacky API, imo. I'm not firmly against a complementary cumulative distribution in histplot but I would be interested to know when you'd want to use a histogram for that rather than a ECDF.

Hi @mwaskom,
thanks for the reply. I didn't check the ECDF function. In fact it does somehow what i want, but the visuals are not as nice, as in the histplot. Especially if you want a bar-chart with a small number of discrete values.

To give you some examples, where i believe the histogram is the better choice:

• scores in sports (e.g. in basketball: display the number of 50+/40+/30+/... games a player has)
• meteorology (e.g. displaying the number of days that exceed a certain temperature threshold or precipitation

In these scenarios a "complementary" cummulative histogram would be very helpful.

Yep, please add this feature as provided in matplotlib. Example would be an abbot curve (horizontal hist plots), e.g.:

Seaborn output unfortunately:
