I'm having some trouble when copying charts out of a spreadsheet file into an
open document text file in open office 3.1.
Normally simple charts can be copied by ctrl+c and pasted by ctrl+v without
problems into writer-files. 
If I'm constructing more complex charts from scientific data the charts somehow
are broken in one or the other way. I have constructed a line-chart with 2
data-series, which looks perfectly right in calc but after copy-paste into
writer one of the 2 data-series is inverted for no reason.

To reproduce this issue use this sample-data in csv-Format:

Open this csv-file with calc, then copy the data into a new spreadsheet.
Create a chart of the type xy-scatter using the chart button in calcs toolbar.
Choose lines only, click next, ignore the field data range and click next.
Click add to add a new data-series.
Leave the name blank.
Use the column x1 as x-values for data-series one.
Use the column y1 as y-values for data-series one.
Click add to add a new data-series.
Leave the name blank.
Use the column x2 as x-values for data-series two.
Use the column y2 as y-values for data-series two.
Click finish.
Click anywhere in the spreasheet document to deselect the chart.
Then click on the chart to select it again and press ctrl+c to copy it.
Open a new writer document and paste the chart by pressing ctrl+v into it.
