Second x-axis for line graph

I need to create a line graph with two x-axis (!) in MS Excel 2002.

1) One x-axis should display the date, the other x-axis the day number, eg.
12/24/04 = day 1, 12/25/04 = day 2...

2) I also want to re-start numbering the day number in irregular intervals,
while series one starts on 12/24/04, series two will start on 1/25/05, series
three on 2/20/05...

Thanks for your help on this!

Begin by changing from a "Line" graph to an "XY (Scatter)" graph. The
"Line" chart is misleadingly named; it has nothing to do with whether
you want lines or not, rather it is a graph where the x-axis is
categorical rather than numeric. Any (optional) x-values supplied to a
"Line" graph are interpreted as category lables, even if they appear to
be numeric. Consequently with a "Line" graph, the only way to start
series at differnt categories is to include blank lines for each
category to be skipped.
