Mapping Sales Data

Discussion created by Jim.McIntosh83 on Nov 16, 2010
I hate admitting this, but I new to using Spatial Analyst and I'm still getting my sea legs.  I'm trying to plot out sales for about three hundred sites and model it spatially.  I've tried using the IDW interpolation and I've gotten mixed results.  Is there a way to have the edges be less pixelated?  How can I get the IDW to stretch beyond the edge of the data?  Is there a better tool I could use for this situation?  Thanks
