Plot data from matrix longitude, latitude and variable

Hi!

I have the matrix, data_1 (attached), and I want to make a map from South Atlantic with coast lines. The matrix is longitude, latitude and the variable as columns. Each lat and lon represent positions where is data, but I would like to have an interpolation.

Thanks!

x = linspace(min(data(:,1)), max(data(:,1)), 200);
y = linspace(min(data(:,2)), max(data(:,2)), 200);
[xg, yg] = meshgrid(x, y);
zg = griddata(data(:,1), data(:,2), data(:, 3), xg, yg);
p = pcolor(xg, yg, zg);
p.EdgeColor='none';
