It seems to me that inverting values on a chart prevents the values from being stacked.
Four WAN interfaces on one firewall, plotted on one chart. The positive DCIs seem to be stacked correctly but negatively is not. Alternatively, I might be misunderstanding how stacked graphs should work.

Yes, this is currently a known limitation / issue.

See #859 on bug tracker.

Only non-inverted sources are stacked according to the ticket.
Can you please confirm that is how it behaves (seems so from your screenshots).

I have posted the same graph twice, one with stack enabled, one without and I think it demonstrates two distinct issues.

1) Negative is not stacked.

2) A DCI that I have specified to be inverted but in this dataset happens to be 0 for the entire series [WAN link is down so throughput is 0] is rendered above the positive values rather than at x=0. See the thin green line on the top of nxwanstack.png. Is this worth opening a separate bug for?

Yes, please open a separate ticket for that (issue 2.)
