after you successfully assign the array, look at the chart and select that
series. Look in the formula bar to see how your data is stored. The
maximum length of a formula is 1024 characters. I suspect you are bumping
up against this limitation.

I was using arrays (sngle column) to specify the values to plot using
code similar to this:

ActiveChart.SeriesCollection(1).XValues = PosLvlMtx

PosLvlMtx was defined as a single array.

Whenever it got to the line ActiveChart.SeriesColection.NewSeries I would
get this error:

"Object Variable or With Block Variable not set"

PosLvlMtx had 17 rows. I then changed it to 14 rows and it worked
perfectly OK!

Has anybody else ever struck this problem? Anybody know of a workaround?
