Data Graph invert axis

[JoeLowry]

I need to create a line data graph showing depth values on the y axis. I can invert the axis using the GUI in ArcMap using advanced properties, but I need to do the same thing programatically with arcobjects. All my code works fine except this last detail. So far I have not found the correct interface to do this. I've looked at DataGraphTVerticalAxisProperties, DataGraphT classes, but no luck. Any thoughts?

It's been awhile since I've worked with the graphing objects but from what I remember there are properties exposed in the ArcMap UI that are not exposed through the ArcObjects model.  This may be one of them.  You might want to look into creating a graph template file which you can load when creating the graph.  After loading the template you can then change any properties that need to be updated for your current graph.
