Okay so, I am working on ArcGIS 10.1, and Visual Studio 2010.My objective is to build an add-in that allows for a user to push a button and create a transect (line) in ArcGIS. That line will output profile graph. I know you can do this with 3D analyst, however 3D analyst does not output more than one graph at a time if you have multiple rasters or GRIDS. So I want to be able to have 3 rasters on and create a transect and that transect will output 3 different profiles but of the same line. So far, I have been able to build the add-in up to the point of creating the line. So the code below allows you to draw a line. But now I am stuck in how do I make this line interpolate the data from each raster and output a separate graph?
