Graph2d customized options.format.minorLabels function causes validation error

[physchemcoder]

I define the customizeMinorLabels function below to add unit(like s or ms) to the minor labels in the Graph2d X axis. It actually works and I can see the customized minor labels. But I also see the error message below shown up in developer console window. It seems that validation code is not happy with my customizeMinorLabels function. Is it a code bug in validation? Or I don't use minorLabels correctly?

"Invalid type received for "minorLabels". Expected: object. Received [function] "function customizeMinorLabels(date, scale, step)"

function customizeMinorLabels(date, scale, step) {
    var minorLabelsFormat = {
        millisecond: 'SSS',
        second: 's',
        minute: 'HH:mm',
        hour: 'HH:mm',
        weekday: 'ddd D',
        day: 'D',
        month: 'MMM',
        year: 'YYYY'
    };
    var minorLabelsUnit = {
        millisecond: 'ms',
        second: 's',
        minute: '',
        hour: '',
        weekday: '',
        day: '',
        month: '',
        year: ''
    };
    var format = minorLabelsFormat[scale];
    var unit = minorLabelsUnit[scale];
    return format && format.length > 0 ? vis.moment(date).format(format) + unit : '';
}

var optionsForIOSize = {
        sampling: true,
        drawPoints: { enabled: false, size: 3 },
        interpolation: false,
        legend: false,
        clickToUse: true,
        start: startTime,
        end: endTime,
        dataAxis: {
            left: { title: { text: "Throughput(MB/s)" } },
            right: { title: { text: "QueueDepth" } }
        },
        format: {
            minorLabels: customizeMinorLabels
        }
    };

Thanks for the report. Can you do this as a jsfiddle / jsbin instead? Its a lot easier to reproduce that way, and ensures we have common understanding of the problem.

Thanks for prompt response. Here you go. Please let me know if it doesn't work for you. http://jsfiddle.net/3c48r3w2/7/

Can anyone take a look at the repro? Thanks.

Please don't feel ignored. There are a lot of issues, and every developer is doing this on their own time, so sometimes it takes a while.
