Created attachment 90640 [details] Writer document with one chart, copied in Writer from Calc. Open Calc. Create something like time 1 2 3 4 length 2 4 6 8 ordered in a row. Create a x/y chart in calc. Copy this chart to writer. It would be shown right. Save the wirter-document Close LO, the reopen again. The chart in the wirter-document is shown right in all LO-version up to 4.1.0.1 rc. Since 4.1.0.2 rc Writer reads only the first 2 data-columns.
The bug has been gone in LO 4.1.4.2 rc and also LO 4.2.0.0.beta2. So I will close this bug as worksforme.
