OR

The OR operator allows you to see all the reports that fall under any one of the categories you select.

For example, if you had selected categories A, B, and C, then you would see all the reports that were labeled as falling under category A or B or C. Some of the reports shown may only fall under category A. Others may only fall under category C. Some may fall under both category A and B.

When the OR operator is selected, dots will be colored according to the categories selected. For example, if you have selected categories A and B, where A is red and B is blue, then all dots will be purple since purple is the color you get when mixing red and blue.

AND

The AND operator allows you to see all the reports that fall under all of the categories you select.

For example, if you had selected categories A, B, and C, then you would see all the reports that were labeled as falling under category A and B and C.

When the AND operator is selected, dots will be colored according to the categories you have selected. Since every report shown will fall under all of the categories selected, all of the colors of the categories selected will be merged and the dots will have the merged color.
