I saved a graph with evidently bad characters in the name. Either + or &. The graph name is displayed in the Saved Graphs list with the characters stripped, but A) the graph isn’t displayed B) I can’t delete the saved graph. Can I edit the suspect configuration file(s) directly through File Manager?
The graphs are all saved in the /graphs directory with hashed eight character filenames. The content of the files is Json and the name of the graph is usually the first object in the file. So clicking on each of the files in turn and reading the names from the editor you can identify the bad file and delete it with the file manager.
Thanks. That fixed it. In the text file, the invalid characters had been replaced by spaces, but in the graph+ left panel only displayed with one space I think.
