Item and Test Characteristic Curves for multiple groups

Hi @technocrat,
Yes, I'm looking for ICCs with separate plots per item (which I will put into a table of three plots per row), as well as three TCCs comparing two groups at a time across three plots (same format as my question on TIFs: GGplot - Test Information Functions for multiple groups). This post also contains a link to a sample of my dataset.

I'm looking for the lines to be consistent, so the same linetype will be used for each group across plots, and they will be in black and white (solid, dashed, dotted). Thanks!
