How do I enter the break points for the “Custom” class breaks method?
The values that are entered in the text boxes correspond to the upper value of each data class. For example, assume that the lowest data value for a particular dataset is “15.0.” If you enter “25.0” in the first text box and “35.0” in the second text box, then the data ranges for the two lowest data classes will be “15.0 to 25.0” and “25.1 to 35.0.” The number in the rightmost text box is automatically entered and cannot be manually changed; this value corresponds to the maximum value for the dataset, which by default corresponds to the upper value of the last data class.
