The following code snippet successfully draws a graphic polygon and fills it with the specified picture fill symbol. When the x values for all of the points are made negative and a repeat call to the snippet is made, the polygon is symbolized but it is not visible. However, when you grab one of the resizing grips of the polygon graphic and stretch it a little the symbolization becomes visible. Can anyone vouch for this behavior? Is this a bug with ArcGIS maybe? I'm completely baffled etc.
