Hello,
Considering your amazing efficiency on pandas, numpy, and more, it would seem to make sense for your module to work with even bigger data, such as Audio (for example .mp3 and .wav). This is something that would help a lot considering the nature audio (ie. where one of the lowest and most common sampling rates is still 44,100 samples/sec). For a use case, I would consider vaex.open('Hu

Implements {DataFrame,Series}.empty

The plotly plots on my macbook on Ubuntu 20.04 and pandasgui 0.2.3.2 have very tiny font. Wondering if there's a way to change this.. See pic below.

Update the TPCH example to support query 6:

select
	sum(l_extendedprice * l_discount) as revenue
from
	lineitem
where
	l_shipdate >= date ':1'
	and l_shipdate < date ':1' + interval '1' year
	and l_discount between :2 - 0.01 and :2 + 0.01
	and l_quantity < :3;

The value of the indicator is different because you are using LOG10 instead of the natural logarithm.
Although Math.log10 is also listed in the source you provided, it is possible that it is replaced by the original ln (x)
JavaScript also changes the name of the ln () function to log (), and mathematically log () is log10 ()

It is possible that log in chopindex Tvw is wrong, but the question

Problem description

When I use the function of concatenating multiple columns, I find that it does not handle null values as expected.

This is the current output

df.concatenate_columns(["cat_1","cat_2","cat_3"],"cat",sep=",")

I'm using black and isort for other projects (see e.g. https://github.com/hyperopt/hyperopt/pull/748/files) and find them quite useful to have more consistent codebase. I think you should drop python3.5 support though, as black is python3.6+. Is this something you would be open to consider?
