Do you want to use the Robinson projection (or any other projection)?

If yes, then you will require access to the Mapping Toolbox.

Hi again,

it doesnt matter.

i only need the the map within the specified limits.

[Dyuman Joshi]

Hi Dyuman

How about the following?

data = readmatrix("https://jp.mathworks.com/matlabcentral/answers/uploaded_files/1515856/plot_map2.csv");

figure
geoscatter(data(:,1), data(:,2), "m.")
geobasemap topographic
geolimits([-30 45], [-20 50])
