I am working with a set of data. Lat, Lon, and Data values. Each in one column in excel (A,B,C). I want to pin each location of my lat lon on the map and use the data value which is 1X1 array to apply a density color scale. The color will vary based on the intensity of the data value. I tried Pcolor, surf,mesgrid I seem to be running the same error with my data not being 2D dimensions.

Please help.

If you want to use your value as the color, I recommend geoscatter.

lon = (-170:10:170);

lat = 50 * cosd(3*lon);

C = rand(1,length(lon));

geoscatter(lat,lon,[],C,'o','MarkerFaceColor','flat')

colorbar

My goal is to plot a polygon using Lat and Lon coordinate on the US map from one set of data. Now I have a different set of data that have lat and lon coordinates and data measurement values. The coordinates of the new data set fall inside of the polygon. I want to plot those coordinates with respect to the data values and see the intensity of those values inside the polygon.
