Satellite color not changing dynamically

I want that the satellite color changes to that of its current network manager.

When i move frame by frame by using advance function the color changes occur in the simulation but when I use the loop:

while sc.SimulationTime ~= sc.StopTime
    sc.advance();
    for leo_in=1:size(leo_satellites)
        for nm_in=1:size(network_managers)
            if detect_change_nm(leo_in,nm_in) ~= size(access_list{leo_in,nm_in}.accessIntervals,1)
                detect_change_nm(leo_in,nm_in) = detect_change_nm(leo_in,nm_in) + 1;
                % change color of satellite same as its network manager
                leo_satellites(leo_in).matlab_sat.MarkerColor = network_managers(nm_in).gs.MarkerColor;
            end 
        end
    end
end

The simulation shows the initial color only.

Color change occuring when moving frame by frame

:

Originally they were red and not changed to green even though they must change color according to the code (using above loop)

drawnow() ?

Hi Krish,

In MATLAB, when you run a loop that updates graphical objects, you often need to manually force the graphics to render the updates. This is typically done using 'drawnow', which is a MATLAB function that forces the figure window to update and display any pending graphics events.

Here's an example of how 'drawnow' can be used:

x = 1:100;
y = sin(x);

figure
plot(x, y)

for i = 1:100
    y = sin(x + i/10);
    plot(x, y)
    drawnow   % Usage of drawnow
end

Please refer the below documentation for 'drawnow' function: https://in.mathworks.com/help/matlab/ref/drawnow.html

I hope it helps!

Thanks for your response but it is not working.

Can you please send the complete code files?
