Which panel to choose for 2D data?


Sorry in advance if this topic is a duplicate or not phrased properly. I’m struggling to put words on what I need.

I have a postgres table with timestamp, velocity values and most important a position value (say from 1 to 30).

I’d like to organise all of this as a map-like panel, with timestamp as X axis, position as Y axis, and the color mapped to the velocity.

I can’t seem to find what I need seems it seems the colors can only be related to frequency so it is not exactly what I need.

I’m still a new user if Grafana so sorry if this seems utterly easy.

Thanks a lot!
