Color specific values on specific measure

Hello,
We set color to specific value configured in "Measures".
Report works ok if I predefine 2 Measures where I want to color the second one "v1" (based on the array).

If my user go to Fields->remove the first measure "v0", then "v1" becomes the new "v0" and my function fails.
How do I retrieve the "v[NNN]" value based on the name of a specific "Measure" so that, instead of setting "result.data[c].v1", I use something like "result.data[c].MY_MEASURE.value" or something similar?
Here is my code:

function onReportComplete() {
pivot.getData({}, function(result) {
var column = "";
var record = new Array();
var minValue = 0;
var maxValue = 0;
//Get all rows event totals and repeated lines
for (var i = 0; i < result.data.length; i++) {
if(result.data[i].r0){
if(column != result.data[i].r0){
column = result.data[i].r0;
record.push(column); 
}
}
}
//Get only unique rows
record = record.unique();
for (var r = 0; r < record.length; r++) {
minValue = Number.MAX_VALUE;
maxValue = Number.MIN_VALUE;
for (var c = (record.length+1) ; c < result.data.length; c++) {
if(result.data[c].r0 && !isNaN(parseFloat(result.data[c].v1)) ){
if(record[r] == result.data[c].r0 ){
// Here we assume that values evaluated are in "v1" position as there are 2 Measures in the report
// If I take out the first value in "Measures" my value will be in "v0" and logic will fail 
// How do I set dinamically the v[n]?
minValue = Math.min(minValue,result.data[c].v1);
maxValue = Math.max(maxValue,result.data[c].v1);
}
}
}
Min[r] = minValue;
Max[r] = maxValue;
}
pivot.refresh();
});
}
