Highlight specific bars in a Bar chart of a pivoted table

[Raghad_Awwad]

Hello Looker Community,

I would like to highlight a subset of my data, specifically I would like to bring attention to the first 7 days of each month.

The dataset is comprised of daily sales of two months, with 2 dimensions [Month, Day of Month] and 1 measure [Sales] and the table is pivoted by month.

I would like to some how visually separate the data based on the value of day of month dimension

Thank you,
