That would be extremely useful! I'm surprised there aren't more upvotes on this. I just wrote a similar issue https://github.com/orgs/foxglove/discussions/803 but this one formulates the feature request more generically |

A common pattern in planning, perception, or controls is producing several candidate options (paths, trajectories, etc) at any time. These candidates may appear in a single message (as arrays of candidates). An engineer may want to visualize these different candidates against one another on a single plot.
The current plot panel allows a user to plot arbitrary x/y values from an array within a message using the current x-axis setting. This setting (like the accumulated) setting only allows the user to select 1 x-axis value and explicit multiple y-axis values.
We should provide a way to allow the user to select arrays of x/y values and plot each array of x/y values as a dataset.
