Via a Python toolbox I am calling arcpy.CreateGraph_management('default.tee', graphobj, 'temp'), where graphobj is a graph object created using the arcpy.Graph() class.
When I execute my tool, the create graph call is made without error, but a graph is never displayed. Additionally, the graph does not appear in the Graph Manager. Oddly, when I start to type the CreateGraph command into the command prompt, I see that 'temp' is available as a '.grf' file to fulfill the first argument.
The CreateGraph documentation suggests that the graph needs to be added to the 'host application', but does not provide any guidance. How can a PythonToolbox create a graph and then display it?
