Dave -
In a scatter chart, if X or Y are zero, there is no point plotted for
that data pair. Shouldn't be zero unless you go to Tools menu > Options
> Chart tab, and specifically choose to plot empty cells as zero. Of
course, if what you're calling blank is really a formula that returns
"", Excel thinks it's a bit of text, and treats it as zero.
I'm not sure what you mean by "stops plotting there", unless you're
letting Excel auto-select your data range, and both X and Y are missing.
Excel autoselects until it reaches what looks like the end of a given
range. If only X or Y are blank, it selects further, but if both are
balnk, it ends the selection. You can override this wild guess of
Excel's by selecting the whole of the data area manually.
