Overlaying graphs without using twoway

[Wonhee Cho]

Hello Statalist community,

I would like to create a graph by overlaying two independent graphs I created using stata.
Is there a way to combine graphs without using the twoway command?
Or is tw the only way to overlay graphs?

Thank you in advance.

It may be possible, or it may not. That really depends on the details.
