Charts: Deleting zero values

> Is there an option...[that] skips any value is zero?

Don't chart the value containing zeroes. Instead,
chart a transform created using the formula,
=IF(B2,B2,#N/A), where B2 is a reference to the
first original values. Copy this formula down
to transform all of the original values.

> Is it possible that it skips this point even in
> the scale?

Since only filtered rows will be plotted you could
dispense with the transformation described above
and apply an AutoFilter that excludes records whose
value equal 0. But, keep in mind that numeric
date values will be interpeted as such and depending
on your X-axis scale settings AutoFiltering may not
prevent a given date from appearing as an X-axis label.
If your X-axis contained categories (as would be the
case if you converted your dates to text values) then
you wouldn't see your excluded date value under any
circumstance; however, your X-axis labels would
no longer be a time series.
