How can I represent EOFs?

I have a matrix of 47 lines and 3 columns which show the EOFs at 47 measurement places. I also have two vectors with the latitude and longitude at which the stations are located I want to plot 3 maps, one for each EOF in which 47 points are shown

for plotting them I use geoshow as:

       ax = worldmap('angola');
       load coastlines
       setm(ax, 'Origin', [0 20 0])
       plotm(coastlat,coastlon);
       hold on
    for i=1:47
     lat=latitude(i)
     lon=longitude(i)
     value=EOF(i,1)
     geoshow(ax, lat, lon, 'DisplayType', 'point')
    end

I have no idea on how can I represent the values in the variable value on the map. Any help is welcome. Thanks for reading.

https://en.m.wikipedia.org/wiki/Empirical_orthogonal_functions would seem to be the appropriate meaning of EOF here?
