I've lately been working on feature classes with a huge number of polygons (e.g. all of the Census blocks within the Chicago metro area). I've been needing to symbolize them by quantities a fair amount to display demographic information, but because there are so many polygons I receive the
Maximum sample size reached. Not all records are being used. Use this sample or change maximum sample size. message every single time.
I know that I can can manually change the sample size by pressing the
Sampling... button in the Classification window, but I'm wondering if it's possible to change the default sample size somewhere, so that I will no longer have to go through this whole rigmarole. I haven't been able to find anything in Esri's documentation.
