Arrow label formatter (waterfall.getArrow(0).label().format()) can take a function with the following context:

function(){
     // Next stack is the one to which connector goes. Previous is the one out of which connector comes.
     // Context:
     // this.value - Sum of values in the next stack.
     // this.absolute - Contribution percent of the sum of values in the next stack, relative to the absolute value of the previous stack.
     // this.percent - Contribution percent of the sum of values in the next stack, relative to the sum of values of the previous stack.
   return this.value; // Default format value.
}

These values can also be used as string tokens for labels formatting. Learn more about text formatting.
