If you go to the Column Control window (by clicking on "Views..." in the
map display), you see a list of column types on the left hand side,
and a list of actual columns in your map on the right side.
For those column types that can display Positive and Negative
relationships by colour, including all Interval and Point column
types, you can click on a column on the right side, then select
"Configure column" from the menu, and set the colours for Pos and Neg
relationships in the resulting configuration window.
You can save a complete configuration as a View object, again from the
menu in the Column Control window.
