Dear all,
I have a dataset such as column 1 is latitude, column 2 is longitude, column 3 is height and column 4 is a value I wish to color code.
The dataset is a trajectory on which is measured an anomaly in concentration (ppmv). I
I would like to plot a 3D scatter geographic plot with the trajectory color coded based on values in column 4.
I don't know how to proceed.
Thank you,
Best regards
Mélanie

scatter3(X,Y,Z,S,C)
Where S is the size of the markers (a scalar value in your case) and C are your column 4 values.
For geographic coordinates,
geoscatter(lat,lon,A,C)
