I have created a chart from an array that has X-Y values. the tooltip shows a weird number for the X-axis (see screenshot) Any idea how to fix this?  
I'm on v3.1.10 and using the ui-chart from the node-red-dashboard pallet v3.6.5

that is a timestamp and this is a timeseries graph (not XY)

if you dont want any thing appearing in the tooltip, you can try putting a space in the X-Axis Label box in the config.

this is not an elegant way obviuously.

try using Dashboard-2 if you are new to NR.
