Conditional formatting with color scale macro/script for many columns

I need to make daily report and put color scale under conditional formatting tab.But since there are so many columns (I have 76 column), I need automatic script to make it like below picture.

The closest solution I found is below macro script (it applies horizontally, what I need is a vertical one)

Currently, I did that manually go to one by one column and apply the color scale.

I need a way to execute color scaling in a column format to run vertically without doing it manually like picture 1.
