How to count mixed NULL/NOT NULL result sets

[Sebastian2]

Let's say I got a table as search result like this:

Object Name                               | Field_A                                 | Field_B
_____________________________________________________________________________________________________________
object_a                                  | value_AA                                | value_AA
object_b                                  |                                         | value_BB
object_c                                  | value_A                                 |
object_d                                  | value_DD                                | value_XX
object_e                                  |                                         |
object_f                                  | value_FF                                | value_FF
object_g                                  | value_GG                                |
object_h                                  | value_AA                                | value_AA

So I got different objects, with maybe different maybe not different values. The information I want:
1. How many objects do have a Value in Field A AND Field B while Field A AND Field B do have the same value
2. How many objects do have a Value in Field A AND Field B while Field A AND Field B do NOT have the same value
3. How many objects do have a value in Field_A but not in Field_B
4. How many objects do have a value in Field_B but not in Field_A
5. How many objects have both, Field_A and Field_B empty

So my desired result would look something like this:

Both and equal (1)    | Both but Different (2) | Only F_A (3) | Only F_B(4) | Both empty (5)
_____________________________________________________________________________________________________________
3                     | 1                      | 2            | 1           | 1

Try something like this

your base search | eval Type=case(isnotnull(Field_A) AND isnotnull(Field_B) AND Field_A=Field_B,"Both and equal", isnotnull(Field_A) AND isnotnull(Field_B) AND Field_A!=Field_B,"Both but different",isnotnull(Field_A) AND isnull(Field_B)," Only F_A", isnull(Field_A) AND isnotnull(Field_B),"Only F_B",1=1,"Both empty") | eval temp=1 | chart count over temp by Type | fields - temp

Just added field temp for chart command to produce columns for each value of field Type.

sorry 4 my late answer - that worked out of the box. Thanks!
