Hi,

It depends on the chart type.
I created this single line by changing the source data for a column chart.

ActiveChart.SeriesCollection(1).Values = "=Sheet1!R2C2:R6C2"

No problem whether the range B2:B6 contains values, #N/As or is empty.

Change the chart type to Line and try using all empty or #N/A data and
it will raise a error 1004.

If your chart is not too complex you can change the type in order to
manipulate it and the return the chart type to that you want.

Cheers
Andy

If the SeriesCollection Object on the chart has all values contained within
it as "#N/A", then the object effectively becomes invisible from the code
and when attempting to set the values to it again via code, it errors out as
the code can't see the object on the Chart Object (Note, Chart Object isn't
the same object as the ChartObject Object).

However, on the spreadsheet side, one can clearly go into the DataSource of
the chart and see it there. What needs to be done to get this issue
resolved as I must still be able to print out the charts, even if at least
one of the series contains all "#N/A" values, which is needed for
interpolated charts to work properly.

For the time being, I'm having to do this manually, and I don't like that
idea.
