Set timestamp value in chart

I would like to manually set in a chart not only the value (Y-axis) but also the the time-stamp (X-axis) corresponding to the value. My application is continuously receiving value/timestamp pairs form an external device, and I would like to keep that timestamp when adding the value to the chart, instead of letting the chart to set automatically the timestamp.
Is it possible to do this?

Yes if you read https://github.com/node-red/node-red-dashboard/blob/master/Charts.md

Thanks, that is was I was looking for.
How could the x-axis label be customised to show for instance also the date (YY-MM-DD) additionally to the time HH:mm:ss?

just set the x-axis label however you want - including full custom
