Depicting cognitive fixation over time

I’m looking for some help with my study of cognitive fixation during acute medical emergencies in the operating room. My question is how to depict the elements of this cognitive fixation. The goal of the graphic is to highlight how attention (represented by diagnoses, treatments, symptoms noticed) widens, narrows, persists or ceases over time. (E.g fewer symptoms noticed = narrowing of attention). If anyone has examples of how this sort of thing has been handled well by others, can improve on my ideas, or suggest good software for doing a better job than I’m proposing below, I’d be very grateful. The data are diagnoses considered, treatments pursued, symptoms noticed, and a leading vital sign (oxygen saturation.) My current idea is to depict diagnoses in columns (with x’s or dots), time in rows, with diagnoses treated appearing in a different color than diagnoses not treated. I would capture the clinical signs considered with a color scale behind the diagnosis x’s (darker could equal more clinical signs considered.) Thanks for your help!
