Dear all,
I am trying to create a combined figure with four histograms using the
graph combine command.
After each histogram I type: graph save graph1 and so on for the
others, then I write this command:
graph combine graph1.ghp graph2.ghp graph3. ghp graph4.ghp
but I receive this errore message:
graph1. ghp is not a memory graph and the same for the others.
Could you please help me to understand where I have made a mistake?
Thank you very much,
Best,
Bea
