Plotting Latitude, Longitude and a variable

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!!

Thanks!

[KSSV]

[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');
colormap(hsv)
