In this example, a new TGraph object is created and then the SetName function is used to set a name for it. The name is set to "myGraph". Example 2:c++ TGraph *graph = (TGraph*) file->Get("myGraph"); graph->SetName("newGraphName"); ``` In this example, a TGraph object is read in from a file and then the SetName function is used to set a new name for it. The new name is set to "newGraphName". So, in essence, the TGraph SetName function is used to set the name for a given TGraph object in ROOT C++ programming.
