displot(kind='ecdf',..., log_scale=True) not working

The following line of code gives an error:

sns.displot(kind='ecdf', data=df, x='col_1', log_scale=True)

UserWarning: Data has no positive values, and therefore cannot be log-scaled.

My data is all positive and kind=‘hist’ or ‘kde’ works just fine.

Actually, I think there is a bigger problem. Even with the numbers that are bigger it doesn’t give a reasonable cumulative distribution.

Have a look at this:

sns.displot(kind='ecdf',x=np.random.lognormal(mean=-1,sigma=1,size=1000), log_scale=True);

sns.displot(kind='hist',x=np.random.lognormal(mean=-1,sigma=1,size=1000),
            log_scale=True, cumulative=True,
            element='step', bins=1000);

I think those plots should end up roughly the same. The upper plot is definitely wrong.

Indeed, though fortunately the result ends up being fairly obviously wrong visually, as you discovered.
