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
