Adding axis labels to dashboard line chart

[ruk-shan]

I have created a chart to display network ping time. But I can’t add labels to x and y axises. How can I do it, ? Can I add labels with CSS? If yes pls point me to a good example.
Thank u so much. I love node-red and awesome developers/ community.

You can add axis labels by sending this to chart

msg.ui_control = {
    options: {
        scales: {
            yAxes: [{
                scaleLabel:{
                    display:true,
                    labelString:'y-axis title'
                }
            }],
            xAxes: [{
                scaleLabel: {
                    display: true,
                    labelString: 'x-axis title'
                }
            }]
        }
    }
}
delete msg.payload;
return msg;

Oh yes, my bad. If to change scales and axes, it takes to have at least axis scale type for time series

msg.ui_control = {
    options: {
        scales: {
            yAxes: [{
                scaleLabel: {
                    display: true,
                    labelString: 'y-axis title'
                }
            }],
            xAxes: [{
                type: 'time',
                scaleLabel: {
                    display: true,
                    labelString: 'x-axis title'
                }
            }]
        }
    }
}
delete msg.payload;
return msg;
