Edit graph with code

[paulvonhippel]

I've got 20 .gph files and I need to change the titles on all of them. Can I do that with Stata commands, or do I need to do it "by hand" in the Graph Editor GUI?

You can do it with commands. You can specify the files name through the options.

Could you give an example, so that I can give more useful suggestion.

I assume you cannot easily recreate the graphs with the title option. Here is one way, once the graph has already been created:

sysuse auto,clear
scatter price mpg, title(old title)
graph save "Graph" , replace
clear*
graph use Graph
gr_edit .title.text = {"New Title"}

Thanks Scott Merryman! I had not heard of gr_edit. Is it still undocumented? It was as of this 2014 discussion:

Yes, it appears to still be undocumented. To get the correct syntax, I first had to use the Graph Editor & Graph Recorder.
