These Option File Changer functions categorize all values according to the settings specified in the specific Option File Changer icon in the filetree or the associated information reader. The option file changer functions Equal Breaks, Quantile Breaks, Jenks Breaks and Variable Breaks substitute each value with its classified value while information reader functions are simply calculating the breaking values. When classifying values with one of the option file changer functions the according information reader is automatically added together with its dependencies to your filetree.
Open the function settings dialog by double-clicking at the Option icon at the file tree.
The methodology of how the breaks are calculated is explained in detail in the Information Reader section.
