Do all the gaps line up? If not, you won't get the stacked appearance
that I think you're expecting. I figured a stacked line chart wouldn't
offer gaps or interpolated lines for this reason. I was wrong, at least
in 2003. The options are all offered, but whatever is selected, the
chart treats the blank cells as zero values.

In any case, the setting is for blank cells, not for cells containing
any kind of formula or for cells containing zero values.

I hope someone is still reviewing this thread. I'm trying to create a stacked
line chart that has a lot of zero's here and there. When I access the "Hidden
and Empty Cells" dialogue box the only active choice I have is "zero" - the
choices for gaps and lines are grayed out. What do I have to do to get all of
the choices?

Want to see something fun? Make a line chart with a missing value in the
middle, set the option to connect points across a gap, then convert to an
unstacked area chart. Where the area chart would have shown a gap with
vertical sides, now the area is filled up to the top of the chart between
vertical sides. If you copy the chart, the copy treats the gap as a zero,
and when you change back to gap, you get the gap to the bottom, not the
block to the top.

Only the unstacked area charts give you a gap with vertical sides (and as I
mentioned, the copy of one has its option reset to zero). The stacked ones
can only treat the gap as zero.

Hi,

The NA() trick does/did not work with area charts.
xl2003: the gap in data results in a zero value. The Empty cells options
of Gap/Interpolate are the same, zero.

xl2007: the gap plotted as zero is as expected. Plotted as gap produces
shear drops between gaps.

The only way to fill the gap is to use another series to plot the missing
values. You will need formula to calculate the interpolated values.

Cheers
Andy

Bernard,
That worked for bridging the gaps in the line plot, but not the area
chart.
The area chart has the "connect" grayed out. Also, if I enter =na(), it
treats them as 0's and doesn't interpolate.
Any suggestions?

Click the chart to activate it
In the Design tab of Chart Tools, click Select Data
A dialog box opens, look at lower left corner for "Hidden and Empty
Cells"
button and click it
You get three options: gaps, zero and connect.

Alternative (works in all version of Excel); in the empty cell type
=NA().
It will display as #N/A and will be ignored by the chart engine

best wishes

XL 2007 doesn't have the TOOLS-Options-Interpolate menu and choices.
This goes for a line chart as well.
Thx
