The goal is to style a polygon layer using graduated colors, something like
-9999 < value < 0 --> some color
0 =< value < 0.1 --> some other color
0.1 =< value 0.2 --> some other color
However, for some reason the number of classes is grayed out.
and when I click on classify:
classes is still grayed out.
Any thoughts?
ArcMap 10.5, the datalayer is using a join of a shapefile and csv table.
Number of classes is 7 and colors are custom (cannot be generated by colorbar).
Change the classification method to something different (e.g. equal interval). Classes is no longer greyed out. Then change the number of class levels to what you require, and then change the method back to 'Manual'.
