Hi! That's my problem: I have datas like this images, the red dot is a wheater station, the blue dots are lightnings, in the axies there are the lat/lon coordinates.
For each lightning I have associated a value (weight) that decrease from the station (in correspondence of this point there is 1) to the the farthest lightning ( ~0). I need that the colour of the dots changes gradually from dark blue (near the station) to light blue (the farthest lightning).
The matrix of the data is 1480x4 (first column -> datenum of the lightning, second and third columns -> coordinates, fourth column -> weight value of the lightning).
The actual code is:
Someone can help me? Thanks!
