There are 2 files in attachment - calc file with 2 original charts and writer file with result copied to writer. In the first chart the same data series are in columns, in second - in rows.
When the first chart is copied from calc to writer, the data appears fine (in spite X labels are partially lost or moved, which seems to be fixed in another bug report). When second chart is copied to writer, the chart data structure is destroyed and the first data row (Y) is now Y value and Y labels completely disappeared.

Result when charts are copied to writer
Looks ok with LO 22.214.171.124 - Win7 x86. Those charts looks identical after copied.
Perhaps same/related to Bug 72727
This report can be closed, I just checked it with 126.96.36.199 and it seems to be solved. The label bug is solved in 188.8.131.52.
Ok let change the status to WFM.
Anyway you can also change the status yourself.. :)
