When you define your range names in the first place, the dialog has a Scope
dropdown, which initially says Workbook. Pick the worksheet name (Data) from
this dropdown to define a worksheet-scoped name. This one wasn't corrupted
in my tests. The reference never changes to the workbook, but stays linked
to the worksheet.

I may not fully understand your reponse but if I did then I'm not sure this
solves my problem. Basically what I do originally is specify something
like:

=Data!rChartDates

Where "Data" is the tab that has the data in it. If I go back to the
chart's
properties after making this change it has automatically updated the
reference to look like this:

='F&O Analysis v2.1.xlsx'!rChartDates

It will stay with this type of reference until i close the spreadsheet and
reopen. At which point i get the behavior I explained and the reference
now
looks like:

=[0]!rChartDates

If i go in and replace the [0] with "Data" then it relinks and becomes
dynamic. THis, however, is not very <idynamic</i if you see what i mean.

I have seen a similar problem, not with the original dynamic chart, but
with
a copy made of a dynamic chart. If the dynamic names are scoped to the
workbook as yours are, the references to the workbook names are
obliterated,
converted to [0]. The corrupted references can only be seen through the
Edit
Source Data dialog, because the series formula is not longer displayed.

I discovered two things.

1. If you use worksheet-scoped names, this corruption doesn't occur.

2. If you save, close, and reopen the workbook with corrupted charts, the
corruption has healed itself, and the charts are as good as the
originals.

I've also filed a very detailed bug report on this behavior.

I did some googling this weekend and found lots of helpful advice on how
to
make dynamic charts with named ranges and OFFSET, INDEX, and MATCH
functions.
Anyway, I was able to successfully create the dynamic charts that I
wanted
by
pointing the series data at a named range. For instance the data range
represented on my x-axis is derived from the named variable
"rChartDates"
which is defined as:

=OFFSET(allDates,0,MATCH(StartDate,allDates,1)-1,1,MATCH(EndDate,allDates,1)-MATCH(StartDate,allDates,1)+1)

This works fine and when I put a reference into my chart I put the
following:

='F&O Analysis v2.1.xlsx'!rChartDates

This too works fine but when I close the spreadsheet and reopen it it
has
lost all dynamic behavior and now the property of the chart looks like
this:

=[0]!rChartDates

Any ideas?
