Creating a chart in Excel that ignores #N/A or blank cells

Question

I am attempting to create a chart with a dynamic data series. Each series in the chart comes from an absolute range, but only a certain amount of that range may have data, a

Answer 1

There is another much less known solution which has merit in some places. Use the #NULL! error which does not plot and does not create a zero point for the plot.

So your plot column is filled with the following construct. Assume real data in column A and that the plotted version is in column C.

=If(Isnumber(A2),A2,A2 A3)

That space is a little known operator to produce the intersection of the two cell addresses or ranges. If there is no intersection then it produces the message #NULL!

Cells containing #NULL! are skipped for plotting purposes.

Aside (For Microsoft) just need to get the maths equations to ignore such cells somehow?
