Cubism.JS threshold scale doesn't work -

i'm using cubism data coming graphite

the data's domain continuos [0,100] , range continuos [0,100] below 100 nonsense modified scale , used threshold scale that:

values < 100 0 , 100 100. tested with:

var scale = d3.scale.threshold().domain([100]).range([0,100])  console.log(scale(1)) //returns 0 console.log(scale(99.9)) //returns 0 console.log(scale(88.9)) //returns 0 console.log(scale(100)) //returns 100 

when apply it, whole chart becomes empty

.call(context.horizon().height(100)     .colors(colors)     .scale(d3.scale.threshold().domain([100]).range([0,100])) // range([0,1]) doesn't work either ); 

without applying scale (notice small white area)

    .call(context.horizon().height(100)     .colors(colors)     // .scale(d3.scale.threshold().domain([100]).range([0,100])) // range([0,1]) doesn't work either ); 

scale didn't work used graphite's functions

specifically used

removeabovevalue(keeplastvalue(xxx),99.99999)
