Month names and trendlines

[tbrownParts]

On the clustered column chart.   I need to do a monthly date average for the past six months that includes a trendline for our service ratings.  I am able to get the visual to look okay when I use X-axis month (for month number) and Y-axis average service rating.   

However, the ask is for month names to be visible on the X-axis rather then the number and to include the trendline.   It appears the visual doesn't support this as when I use the name to option for the trendline disappears.    

What are some ideas on how to go about fulfilling this ask?

To modify the format I need to use data that is imported.  Is there a solution that would work with direct query?

Cannot reproduce.  Works for me in Direct Query mode as well

Put your date column on the trend line but then format it as "mmmm".
