Is there sample code for a XamMap that uses a DistributionScale? I am trying to  assign two MapColorSwatchPanes one for negative numbers another for positive numbers. I want to be able to choose which set of brushes goes with what swatch pane. Is this possible to be accomplished? Say you have a set of numbers such -25, 0 50; I want to assign zero to be in the center of the swatch pane. So that positive numbers always have the same colors.  The issue I am facing is the brush collection is shared and I cannot assign a specific set of brushes to a specific swatch.
