I want to use standard deviation classification method for my map in ArcGIS, but the default class are -0.5 st dev - +0.5 st dev; 0.5 st dev-1.5 st dev; etc. I wonder if there's a way to use 0-1 st dev, 1-2 st dev, etc. Thanks.
Then modify your breaks from there once you get the range values, should you want to consolidate those below the mean
Thanks for the answer. I know how to choose the interval size. My question was how to set the cut off values to be from 0-1 st dev instead of -0.5-0.5 st dev, see the resulted default classes from standard deviation classification method on Classifying numerical fields for graduated symbology—Help | ArcGIS for Desktop . I know i could calculate the mean first and set the limits manually. I wonder if there's an option in ArcGIS to do it more easily. Thanks.
Don't see one, I switch to manual after (jot down the breaks, just in case, most people don't want to calculate the mean or std dev first)
like so... took about 30 seconds to move the slider to the mean, then right-click and remove the negative breaks
