I'd like to present these in a horizontal bar chart such that:


                              [Date]

Tom | PPPPAAPPPAAAAAPPAAAAAA....
        |
        |
Pat   |PAAAPPPAPPPAAAAPPAAAPPAAA..
 
         <Time Start> -----------------------<Time End>

Where 'P' is the colour of the bar representing 'Present' and 'A' is the colour of the bar representing 'Absent'.

I've been at this trying as many permutations in Excel as possible without success. I've googled it and looked for solutions here without success. Can anyone advise, please?

Regards,
