A simple test:

dim iLastRow as long
iLastRow = Range("B65536").end(xlup).row
if Cells(iLastRow, 2).Value Range("A1").Value then
Cells(iLastRow+1, 2).Value = Range("A1").Value
Cells(iLastRow+1, 3).Value = Range("A2").Value
endif

Thanks Again Jon

Went to Excel Programming on David Biddulp suggestion.

Been away from my computer for a while, but just tried your code and got
it
working on the press of a "button", if I use the Worksheet_Change event
excel
locks up because on every change it adds a new line. So I need to modify
your
code so that Column B and C are only updated when the variable value
changes.

Thanks again for your time.

Thanks Again Jon

It is a DDE Link from a PLC that will be providing the variable in cell
A1,
in cell A2 I have a timer variable that counts up in seconds, My
problem
is
creating the code that puts these values in the first blank cells in
columns
B and C

That depends on how the data in A1 is provided. If it's a user-entered
value, you could use the Worksheet_Change event of the worksheet to
note
the
time of the change in the first blank cell in column B and the new
value
of
A1 in the adjacent cell in column C. If it's a DDE link, you could use
the
Worksheet_Calculate event in the same way.

Thanks Jon

But how do I create the mechanism to store the data in columns B and
C.

A chart needs data to plot. You would need some mechanism, probably
programmatic, to record values from A1 as well as times when A1
changes.
These two additional sets of values, stored perhaps in columns B
and
C,
would form the source data for the chart.

Hi

I have a variable in cell A1, that I need to plot a histogram of.
I
need
to
create two axis to create a real time chart, where axis one will
be
an
index
value of when the variable in cell A1 changes value, and axis two
will
be
the
new variable value.

Any Ideas would be appreciated.

Thanks
Alec
