Tools create graph come back to Entity RelationShip

Question

Good night! 

 

Thank you in advance for your help. 

 

I have a problem, create a chart and then use the option: 

 

Tools / create graph / Grid 

 

But I can not convert it back to the diagram Entity Relationship Diagram 

 

What I can do?

Answer 1

To convert your diagram back to a previous state, you can use undo (either "Edit" -> "Undo" or CTRL+Z or the 9th button from left in yEd's tool bar).
