Time format graph
 

hi

i want to 'make' a bar graph which is based on a table which uses the
time format instead of whole figures.

i have a set of times (12.00 to 14.00, or 16.00 to 19.00) in a table.
Every time figure is a separate cell. I would like to be able to
change these times and then the coloured blocks are added or removed
according to the time frame eg. FROM 12.00 until 14.00.

Any ideas??

Thanks
