Why can an Analog Log not handle negative values?

I am using the Analog Log to create trend graphs and keep track of history data. But I noticed that the Analog Log does not store negative values! Any negative value is stored as 0.

Is this a bug or done intentional? I would like to log negative numbers. Or am I doing something wrong here?

It does store negative values for me. Are you sure you have linked the correct input value?

When I use a new Analog Log and use all the default values, then it will register negative numbers.

I found out that setting Write Type to Maximum causes the issue. With Maximum,  the lowest number registered is 0. Kind of strange and not expected behavior.
