Scenario : I have a large data table, possibly 100 cols wide and 100 rows
deep. I have created a graph built from one column worth of data. Can I
create a macro which when used will move the source of the data to the
nextcolumn, with this being carried out repeatedly.

I only want to display one col at a time in the graph. I would like to have
two buttons - one for moving to the next column and one to move back to the
previous column. Is this possible ?
