Basemap is a child package of Matplotlib, which is used to draw maps. Yesterday's push described how to draw a wind direction chart. this article again uses this package to briefly introduce how to draw a color chart of the sea and sea ice temperature, which is common on the NOAA official website. The specific operation is as follows: Basemap is a child package of Matplotlib, which is used for map drawing. Yesterday's push described how to draw a wind
