Nice to meet you. You are looking at 12-hour Gantt chart of your backup cycle (or empty 12-hour graph if you didn't configure OmniGantt correctly).
Using << or >> you can scroll beginning of your time view (left side) or end of your view (right side). That way you can see more events (in 12 hour increments) or less, as long as you see at least 12 hours at time. You can also scroll left and right by modifying left and right side one by one.
Above and below you will see time grid with alternating yellow and red boxes which represent one hour on graph (hover over them with mouse to see numerical representation of hour). Black Bar (|) between hours in midnight and if you point your mouse to it, you will get pop-up with date. I guess that you have found out about label and usage counters on it.
