How to wrap legend text in Chartjs?

问题

My ChartJs legend text is overflowing in the same line when the text is too long. Is there any parameter that I can use to enable text-wrap.

legend : {
    display : true,
    position : 'bottom',
    fullWidth: false,
    labels : {
        fontColor : "#000",
        //  boxWidth  : "3"
    }
}

In other chart libraries like highcharts, you just have to set width and the text will be wrapped if it exceeds the width. Is there such an option in ChartJS?

Highcharts Library Example:

legend: {
    itemStyle: {
        width: 90 // or whatever, auto-wrap
    },
}

I tried using legendCallback, but in that case I will loose the 'onclick' useful functionalities of the legend boxes that come out of the box in ChartJS. So I don't want to do that. Don't want use legend template either.
