Displaying extreme values in raster layer and histogram

Discussion created by kuntalnr on Oct 31, 2013
Dear All
I have two queries:
1. Is there any way to create and display the histogram of my raster file? I want to show pixel classes and corresponding values in the form of histogram
2. I have five classes for my raster image (following a quantile classification) but some very high values are being clubbed with the normal values. For ex my classes are:
The last class contains very high values. Is there anyway I can separate these high values (I do not have any criteria to decide what is the threshold value above which a value is considered extreme. So I want arcmap to decide the threshold value and accordingly put pixels above the threshold value into separate class
