Please don't.

It's easily computable as you traverse the plot info:

            struct gasmix *gasmix = NULL;
            struct event *ev = NULL;

            loop over samples or plot events in increasing time order: {
                    ...
                    gasmix = get_gasmix(dive, dc, time, &ev, gasmix);
                    ...
            }

and our plot info is already unnecessarily big. Let's not add another
redundant element to it.
