ylimits for plotting should not be rounded about tigramite

[jakobrunge]

I don't see where they are required to be int, I just see this in the docstring, which I will fix. Python doesn't require typed variables usually...

It isn't required in the code to be an int, but it is rounded to the nearest half-int or something using _myround. In my original post I've linked to the code for _myround and where _myround is invoked, and I ask that it be removed. Here is the link again: https://github.com/jakobrunge/tigramite/blob/9b6b9316af2fe49dc21fd49ffd32e17fc0d19e4a/tigramite/plotting.py#L574C1-L596C22

Thanks for the catch, maximum and minimum can be floats, fixed in the docstring now, and you can adjust the tick_marks by the "y_base" argument.
