I am creating a polygon using coordinate points with geoplot, and I would like to fill the resultant shape in a partially transparent blue color. I am able to create the filled shape, and I can overlay the outline on the map with geoplot, but I cannot do both.

% Create a geographic axes
gx = geoaxes;
hold(gx, ‘on’);

% Define the indices of visible points
visibleIndices = maxRadiusPerAngle > 0;

% Close the loop by adding the first point at the end
latTargetsClosed = [latTargets(visibleIndices) latTargets(visibleIndices(1))];
lonTargetsClosed = [lonTargets(visibleIndices) lonTargets(visibleIndices(1))];

% Plot the outline of the polygon using geoplot
geoplot(gx, latTargetsClosed, lonTargetsClosed, ‘b-‘, ‘LineWidth’, 2);

% Plot the central point

% Plot the visible points
