Are the added series listed in the Source Data dialog Series tab? if so,
they may be plotted as the incorrect type or against the wrong axes. You can
select a series even if it's somehow obscured by selecting another series
and cycling through series using the up and down arrow keys. Once it's
selected, a series can be moved between primary and secondary axes, and you
can change its type.

Another thing to check is whether you have numerical data in the source data
range for the added series. If the added data is nonnumeric, Excel will not
be able to plot them.

I have an existing stacked bar chart with the left Y-axis as the bar
amounts
combined with a line with the line amounts displayed on the right Y-axis.
I
want to add 2 more lines to my chart. When I add them as new series I do
not
get anything displaying on my chart. The ranges are all okay. What am I
doing wrong?
