getMiddleRange.js

function getMiddleRange(min,max,limit,type)
{
    --limit;
    var new_num
    var data = '';
    for(var x=0; x<=limit; x++)
    {
        var new_num = Math.ceil((max - min) / limit);
        new_num = min + (new_num * x);
        if(x==0){new_num = min;}
        if(x==limit){new_num = max;}
        
        if(type == 'date'){new_num = formatDate(new_num);}
        
        data += '|'+new_num;
    }
