<div dir="ltr">Your question is a little vague. In general it doesn't make sense to plot an array with only one spatial dimension over a map. Could you be more specific about what you are trying to accomplish?<div><br></div><div>You have a 2D array that has dimensions latitude and time, but you say you want to plot it over a map? You only have one spatial dimension, do you mean you want to show where the continents are in the latitude region? Is your data averaged over a certain longitude region?
