Classified Symbology with Kernel Density

Discussion created by ymastrogiovanni on Jun 14, 2013
I have run the Kernel Density tool and am not able to set the Symbology to "classified".
It defaults to the Symbology "stretched" and each time I select "classified" an error pops up with the following:
"This dataset does not have a valid histogram required for classification method, run Caculate Statistics tool to generate histogram."

I ran cell statistics tool....because I couldn't find calculate statistics tool and it added a new layer....which I do not want.
I didn't have this problem before 10.1.
Help please!
