Trying to identify a specific function for placing a value on a globe or worldmap at a lat/lon coordinate.

Is this what you mean for placing value

worldmap worl
load coastlines
plotm(coastlat, coastlon)
textm(45, 30, '123', 'Color', 'red')

Thanks for the reply, what I am considering is how to place a temperature for say Tokyo on a globe. So I'm assuming I'd need to load an array of values onto a globe or worldmap object to display. Have seen several videos on displaying layers or animations with plotm or geoshow functions onto a map but nothing about specific text or variable contents at at a particular set of coordinates.

Thanks for the insight Chunru, textm is the ticket.
