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
