How to make a static vertical line dynamic?

[KalebeRS]

Hello,

I have this dashboard with a graph that shows values per week day, the goal is, with the vertical line as circled in green at the photo, change a value inside assigned to it, dynamically when selecting the filter.

Is it possible to do that? If so, how?

This is not generally possible with a standard column chart, except it can sometimes be spoofed if your x-axis is _time.
