As far as I know (I am very newby in Node-Red), the dashboard node corresponding to "Chart" allows us to represent a variable (Y-axis) versus time (X-axis), besides to bar or pie charts.
I would like to represent a complex value (polar coordinates, which could be converted to cartesian) on a chart. The chart should be refresed any time that the coordinates of the point changes (onece per second or so)
Is there any way to do that?
Thanks in advance
