HOW ???

[Dyuman Joshi]

geoscatter(latitude_data, longitude_data, size_for_each_circle, color_for_each_circle)

[ahmad Saad]

@Dyuman Joshi THANKS FOR YOUR ATTENTION.

@Dyuman Joshi

i try

latitude_data= [15 -10 30];

longitude_data= [25 -10 -5];

geoscatter(latitude_data, longitude_data, 5, 'r')

+++

but it doesnt work.

i need the limits to be ([-30 45],[-20 50]).

my matlab ver is 2018a

[Dyuman Joshi]

@ahmad Saad, Ah, I see that you are working with R2018a. geoscatter() was introduced in R2018b, that's why it won't work for you.

In that case, use geobubble -

latitude_data= [15 -10 30];
longitude_data= [25 -10 -5];

geobubble(latitude_data, longitude_data, 5, 'BubbleColorList', [1 0 0], ...
    'LegendVisible', 'off');

%specify limits
geolimits([-30 45],[-20 50])

@Dyuman Joshi

thanks again.

yes, it works.

however, i get the error:'Undefined function or variable 'geobasemap'."

it gives a grey background

[Dyuman Joshi]

Once again, geobasemap() was introduced in R2018b.

I somehow forgot to check for that before (It's getting late here haha). And I realised that and updated my above comment, just after you commented.

Unfortunately, you will have to work with gray and white.

@Dyuman Joshi

Anyway, thanks for your help.

[Dyuman Joshi]

You are welcome!

Good night :)
