Thank you for your help! It turns out I was successful, but only using rawExpression. I’m unclear on what the problem is with that as a solution, but would love something cleaner.
For anyone else who has a similar question:
In my CL script for the graph, I used:
rawExpression("g"): equation1.latex
And then in the graph itself, I had to have a line that just graphed g, not g(x) or y=g or anything similar. That may be obvious to others, but had me stumped for a bit.
