Visualizaing time series properly

I created a timeseries data of load profiles for on grid electricity consumption for a 24 hour period. To represent the time for running 24-hour equipment like refrigerators my excel file had 0:00 to 23:59 as running time, however when matlab generates a load profile it has 0kw in the last 24th cell. I used time2num to convert the time in my excel to num in matlab. How can I fix this?

plot_loads() calls upon bar2(), which I cannot find anywhere.

You should avoid using sum as the name of a variable, as that conflicts with using it as the often-used function.
