Note: I don't see how to upload the original files here. I'm not confident that
this bug is consistent.

1) In spreadsheet, I make a simple x-y scatter plot of the data listed at the
end. Define each set of y data according only to the applicable x data. (Exempi
gratia, Y2 only includes x values 0 through 4.) If the whole x and y column for
each series is included, then the Chart Data Table will show only 1 x column,
and the plot will be correct.
2) I copy (ctrl c) and paste (ctrl v) the figure into a text file. The figure is
altered such that the third plot is correct, but the other two are offset by one
point.
3) I enter the Chart Data Table and see that the data is still correct. However,
there are no "Data Labels" and each series has its own (correct) x column.
4) I try to alter the x-axis data, and no change is observed (y-axis responds fine)

Speculation: I think this bug was introduced after OpenOffice.org 3.0 (which is
when I started using this feature). I think this is strictly a viewing problem
because I see no evidence that the actual data is being altered.
