这是我的代码，我没有在图表中显示标题。如何为X轴和Y轴命名？

var barChartData = {
        labels : ["January","February","March","April","May","June","July"],

    datasets : [
        {
             title: "My First dataset",
            fillColor : "rgba(220,220,220,0.5)",
            strokeColor : "rgba(220,220,220,0.8)",
            highlightFill: "rgba(220,220,220,0.75)",
            highlightStroke: "rgba(220,220,220,1)",
            data : [randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor()]
        },
        {
            title: "My First dataset",
            fillColor : "rgba(151,187,205,0.5)",
            strokeColor : "rgba(151,187,205,0.8)",
            highlightFill : "rgba(151,187,205,0.75)",
            highlightStroke : "rgba(151,187,205,1)",
            data : [randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor(),randomScalingFactor()]
        }
    ]

}

在选项中添加此参数multiTooltipTemplate："<%=datasetLabel%>-<%''value%>"
