Combination Chart won't display custom data item values

[rboyce]

I have a combination chart, which displays three separate values in a time series. I have put these three values in the Series (primary axis) box; they are called BCWS, BCWP, and ACWP.

ACWP and BCWS are data items tied to previous queries involved in a join. These two values show up on my combination chart.

BCWP is a custom data item, which refers to another data item, which gets the real BCWP values also from a query participating in the join. This data item does not show up in my combination chart, though it displays its values fine in the corresponding list I am outputting with the combo chart.

I am guessing there is a problem with the chart displaying a custom data item, or that the fact it is a copy of another value that is fouling things up.

Any ideas? Hope I described my problem well enough.
