That must have been it. Thanks very much for the help. Now trying to make
it look "pretty!"

Gregor, check the helpfile on Excel specifications and limits (charting).
You'll notice Excel has a limit of 255 data series, 256,000 data points
(32,000 per series). Cld it be you have defined each data point as a
separate series?

I have collected two data points for 18 months, 24/7. Puts that at
157K.
That is Station 1 & Station 2, date, time, reading1, reading 2.
When I went to chart in Excel got the message that the width was limited
to
255 in the chart.

Any suggestion on how to display the data?
