The provided code is almost correct, but it has a few issues. The main problem is that the facet_wrap function is being used incorrectly. The facet_wrap function is meant to be used with a single variable (e.g., “day”), but in this case, you’re trying to facet by multiple variables (“day” and “Posture”). Another issue is that the x-axis breaks are not being generated correctly. The code is using rep(c(8, 11, 14, 17) * 3600, each = length(unique(graph_POST$Date))) to generate the x-axis breaks, but this will result in the same break point for all days.
