Highlighting Data Labels That Have a Tooltip

Hi all! I am new to this community and saw how helpful everyone is and wanted to see if I could get some help with an issue I'm having.

I have a dataset from a poll that returns count of "No" and "Yes",  and Events associated with the month of the poll. I then created measures that calcuate the total responses, % No and % Yes. Currently, things look like this:

Data point without an event

Data Point with an event

Question 1: Is there a way to highlight/mark specific data points that have a tooltip?  In my real data set, I have a very large sum of possible events, so i need a clean way to annotate this data.

I found a solution that is very close to what I need, but I do not like that it adds an additional line in the tooltips and duplicates information. I wrote a measure to return the value of "% No" if the tooltip wasn't empty, and then added that measure to the X-Axis and formatted it orange.

Question 2: Is there a way to show the actual values of yes and no alongside the percent just to give more depth to the data?

I am open to rethinking how I visualize this data if it means a better solution to my problem. Thank you in advance! 🙂
