How can I create a custom indoor map using Mapping Toolbox? for GUI

Hello, I'm trying to create a custom indoor map for a robotics application using mapping toolbox. I already know what the map should look like so I tried to load a map using the imshow command but it ended up showing on top and not allowing me to show anything else on the map. (Is there a fix for this? Can I send it to the back or make it a background for my axes?)

If this is not possible is there a way to create a custom map from data I have using mapshow or geoshow or something? I only need to use Geoshow on top of it to add markers with sensor readings. Below is the create function I'm using for the axes in my GUI:

Omar=[10 10 9;
    20 10 1;
    30 10 10;
    10 20 3;
    20 20 1;
    30 20 1;
    10 30 2;
    20 30 2;
    30 30 4];

mapshow ([5 35],[5 35],'DisplayType','point')
grid on
hold on
i=1;
size =0;

while (i<=9)
    if (Omar(i,3)>0)
        if Omar(i,3)<3
            Color='g';
        elseif Omar(i,3)>2 && Omar(i,3)<7,
            Color='y';
        elseif Omar(i,3)>6,
            Color='r';
        end
    geoshow(Omar(i,1), Omar(i,2),...
        'DisplayType', 'point',...
        'Marker', 'o',...
        'MarkerEdgeColor', Color,...
        'MarkerFaceColor', Color,...
        'MarkerSize', 10*(Omar(i,3)))
    %text(Omar(i,1),Omar(i,2),int2str(Omar(i,3)));
    end
    i=i+1;
end

You can refer to the documentation link that explains about an example 'Overlay Vector on Orthophoto' on how to show an image as a layer on an axes and how to display/highlight a portion of the image on the axes. You can also refer to the example 'Overlay Polygon and Lines on Orthophoto' in the same link.
