'Declare the variable that references the application
Dim GrapherApp As Object

'Creates an instance of the Grapher Application object
'and assigns it to the variable named "GrapherApp"
Set GrapherApp = CreateObject("Grapher.Application")

'Make Grapher visible
GrapherApp.Visible = True

'Declare Docs Plot, Shapes, Graph1, and HighLow as Object
Dim Docs, Plot, Shapes, Graph1, HighLow As Object

'Assigns the Documents collection to the variable named "Docs"
Set Docs = GrapherApp.Documents

'Creates a new plot window and assign it to the variable named "Plot"
Set Plot = Docs.Add(grfPlotDoc)

'Assigns the AutoShapes collection to the variable named "Shapes"
Set Shapes = Plot.Shapes

'Adds a high-low-close graph and assigns it to the variable named "Graph1"
Set Graph1 = Shapes.AddHighLowGraph(GrapherApp.Path + "\samples\hilo.dat")

'Assigns the high-low-close graph to the variable named "HighLow"
Set HighLow = Graph1.Plots(1)

'Return the display type
Debug.Print "Display type = "; HighLow.DisplayType

'Set the display type as candlesticks
