Created attachment 81913 [details] A chart with custom label and a copy of it. When I copy a chart, the data row labels are reset to default texts and I have to manually set them back to there original value, for each data row in each copy of the chart. Steps to reproduce: 1. Create a chart with data rows. 2. For the data row label, do not link to a cell, but insert a custom label in quotes, like "My Label". 3. Display a legend (if there is no legend). 4. Copy and paste the chart in order to duplicate it. The data row labels are not preserved and show the default ("Column 1").
Although your steps are slightly different I believe it's the same root cause of bug 64722 therefore marking as duplicate. I know that this is a copy/paste problem but I think ultimately it's coming down to not reading the value which is stored, so upon opening a saved document or copy/paste you're seeing the "loss" of name. Thanks for the clear steps and for helping us make the product better. *** This bug has been marked as a duplicate of bug 64722 ***
