Q&A Functionality Issue

[BI_Newbie2]

Hello all,

I'm working through some online PL-300 courses and I've run into an issue that the instructor couldn't help me with.

my Q&A visual isn't populating any chart.  It doesn't show anything when I ask a question that doesn't result in a single value ("What was the sales volume per year" ,per the video should've resulted in a line chart).  How do I fix this?  The screenshot is what it shows, even after I add the "Sales volume per year" to Q&A on the Matrix page

my Q&A won't show me charts/analysis of the data, it's only producing a result if there's a single value result to the question.

Is there a way to fix this?

hi, it doesn't have a calendar table but a date and date hierarchy field in the same table

Yeah, don't do that. Auto Date/Time does more harm than good. Invest in a proper data model.

Which data (model) is this visual based on?  Does the data model have a calendar table?
