I am trying to symbolize a layer on Quantities -> Natural Breaks -> Jenks. There are some null values in the column that I'm using for the symbolization, and that causes those features to disappear from the map when symbolized. Is there a way that I can set a default value for the column so that this will not happen?
Thanks
There might be a simpler method than this - but you could add a field, then use field calculator to fill it with the values from the old field. Then use Select by Attribute to select all the rows with a value of NULL, then use Field Calculator again to replace this null value with a different value.
Yes, I tried that too. But because you want to symbolize Quantities, you need a number field and the only way to use Field Calculator is with a Text field so unfortunately this won"t work.
:S Well it isn't working for me. Every time I try to use Field Calculator on a number field it is grayed out. Why would that be?
