How are you setting the data range? Is it programmatically through
some property/method? Or is it through the GUI? If the former, I
believe XL/VBA is translating the 'bottomright' into the current value.
If the latter, I would love to know how, because I cannot set that
through the Chart Wizard.

Bottom line: I don't believe it is possible to specify a multi-column
range through a named dynamic formula. You can establish *up front* a
range for a single column (see the Dynamic Charts page of my web site)
and specify other ranges relative to this column. The examples on the
Dynamic Charts page show how.

I'm having trouble with a graph I'm trying to make dynamic.

I made a named value "bottomright" that returns a reference to the bottom
right cell of my data set. bottomright = OFFSET('Foo'!$B$2,
COUNTA('Foo'!$A:$A)-2, 3, 1, 1). That much works nicely.

The trouble I'm running into is in defining the data range for my graph. I
set the data range to ='Foo'!$B$1:bottomright, and it makes a nice graph
with exactly the data I want in it. When I add data, though, the graph
doesn't update. I go back and check the data range, and it has switched my
variable "bottomright" with a static reference to the cell it pointed to
when I initially set up the graph.

Is there some way to have the data range leave this dynamic? Thanks!
