// figures out a good scope to use based on the data
// this is pretty basic, but does an ok job

var data = [
    { "label": "first", "value": 30 },
    { "label": "second", "value": 86 },
    { "label": "third", "value": 168 },
    { "label": "fourth", "value": 281 },
    { "label": "fifth", "value": 303 },
    { "label": "sixth", "value": 365 },
];

var scope = 0;
data.forEach(function(element) {
    if (element.value > scope) {
        scope = element.value;
    }
});

// factor = "1".padEnd((scope.toString().length), "0");
// var temp = scope / factor;
// var temp2 = Math.ceil(temp);
// var temp3 = temp2 * "1".padEnd((scope.toString().length), "0");
// console.log({ scope, factor, temp, temp2, temp3 });

// simplified version of above:
scope = (Math.ceil(scope / ("1".padEnd((scope.toString().length), "0")))) * "1".padEnd((scope.toString().length), "0");
