Hi, I have three columns (latitude, Longitude and X). I want a plot with latitude as x axis, Longitude as Y axis and the corresponding value of X in the main plot. X has to be colored using gradiant of value of X to get a hsv color.
Sample data attached!!

[num,txt,raw] = xlsread('sample_data.xlsx') ;
lat = num(:,1) ;
lon = num(:,2) ;
z = num(:,3) ;
z(z>500) = NaN ;
scatter(lon,lat, 40, z, 'filled');
