Tooltip with most recent date

[pstp]

I built a YOY line graph with three years of data on it. I have data points for almost every day. The chart is using a calendar week number field from a calendar/date dimension table as its x-axis. I'm having trouble using any date field as the tooltip though. The goal is that when hovering over a set of points, it shows the most recent date in that area instead of just the week number (I've done this with other charts, but data is only from one day a week in those). Any suggestions on how to achieve what I'm looking to do? Image is included.

You drag and drop the Date field from the calendar table to the Tooltips area

@Fowmy That does not work. It will not allow me to drop the field there.

Hi @pstp ,

create a measure like

last date = max('date'[date])

add the measure to the tooltips area

hope that helps

@richbenmintz Is there a way to prevent it showing on every year. I'm using Year as the Legend field and it shows the date for each you. Can I get it to only show for the most recent year/date?
