Thanks - looing through JPs stuff I can't find a solution - it applies to
blank cells in the middle of data not at the end.

My blanks at the end are necessary as the user selects a product then the
data and graph update automatically. As the amount of data changes I need a
formula that returns either data or "" (or something else that the graph
cannot plot).

I'm using a line chart.

I have a list of data which contains a string of NA#s at the end. When I
plot it the graph doesnt plot the NA# but it shifts the line to the left as
if it was plotted. What I would like is the last point of the graph to be to
the very right of the graph to use all the space. If I replace the NA() with
"" i get the same result. If I delete the cell completely the graph moves to
the right as it should.

I'm using dynamic ranges.

Hi,

Thanks for the suggestion.

I'm afraid the chart engine (or at least mine anyway) doesn't ignore it -
it
plots nothing on the graph but shows a lot of empty space which
increases/decreases as i add/delete N/A's.

If i try this technique on a chart without dynamic ranges it doesnt work
either.

Any ideas why this would be different to your result?

Thanks

Replace the blank by #N/A
So let's say your formula is =IF(this-test, B2,"") then use
=IF(this-test,B2,NA())
When the test fails, this displays #N/A which the chart engine ignores
If this looks odd in a print out, use a conditional format such as
=ISNA(C2)
and make the font the same as the cell background - make it invisible on
the
screen and then printed.
best wishes

Hi,

In a chart I have a formula that either returns a number or "" in a
cell.
I
then have a dynamic range set which plots the values on a graph. The
problem
is that the chart will plot the ""s as zeros as it sees something in
the
cell.

Is there a way I can have a true blank cell result coming from a
formula?

If not how I can avoid the dynamic range seeing this as a zero?

Thanks
LiAD
