Trying to station a profile for a pressure pipe run. I'm in the Label Style Composer and I want to get a component line to "justify" down to the bottom horizontal axis. I edited the pressure pipe "feature settings" so that the "Dimension anchor option for pressure pipes" is set to "Graph view bottom." I thought that would allow me to go back into the style composer and select "Pipe Dimension" as an anchor point... ...which would then shoot the line all the way down to the bottom of my profile. Not happening. I was able to do this with one of the Pipe styles... ...so why wouldn't an identically-composed style work for pressure pipes? Very confused.

Thanks for any advice.
