What is the requirement for xarray plot to have a 2-dimensional array?

edit

Xarray plot requires a 2-dimensional array of data to create a plot, where one dimension corresponds to the x-axis and the other dimension corresponds to the y-axis. If the data is not already in a 2-dimensional format, such as if it has multiple dimensions including time or depth, it may need to be reshaped or aggregated into a 2-dimensional format before plotting.
