How can I mark specific points in time on line chart?

[Former Member]

I am using a line chart to denote changes in several values over time.

My Date value is stored by the day, but I have created a Date/Time Hierarchy and am displaying my graph by month.

There is a specific date that I would like to call out on the graph as there are changes that took place at this point in time.

What is the best way to do this?

Attached is a picture of what I'm envisioning, but it's just an example that I took the graph into paint and slapped a line close to the point on the X axis that seemed right.

Have you considered using reference lines?  See

REFERENCE LINE! I knew there had to be a word for what I wanted, I just could not figure out what, and as such couldn't search it Thank you so much , super quick and super simple answer.

To add to this, I didn't know how to add a reference line, and the link provided doesn't say how to add one, just what it does.

I used this video to learn how to add a reference line, and specifically how to add one to a date/time graphy which is exactly what I needed.

Thanks again!
