When merging line graphs into a new graph, I lose the line connecting the symbols. The symbols and error bars are visible, but not the lines. Increasing line thickness does not help. What has happened?
I solved the problem! It was simply a question of ticking the right box. In the original graphs I had checked "connect line across missing data", and this setting was not transferred to the merged graph.
