Is it possible to either exclude weekends from a Chart, or mark them differently?

What I’m trying to do

I’m tracking sleep & other inputs to look for patterns or trends related to productivity (where I’m also tracking hours worked and how many of those were productive).

I have the charts, so that’s not an issue. But the problem is that weekends are outliers as I’m not working & have other personal & family responsibilities. Thus they throw the trends et al off.

I’m not sure if removing weekends is the best approach or ‘dimming’ them somehow.

Things I have tried

Nothing - this seems to involve js that’s beyond my noob skills. I’m looking for some online sources to learn js but at this point, complex js (like mulfok’s custom js for their weekly note chart) is difficult for me to comprehend.
