MATLAB: Dashboard Lamp Covered by Annotation

dashboardguilampMATLABsimulinkzoom

I have a lamp, connected to the 'Left Engine Power' signal, which looks like this:

But when I zoom out (necessary in order to see the rest of the GUI) the lamp is fully covered up by the signal annotation, like this:

The lamp's actually trapped below the part where it says 'Left Engine Power:1'.

Does anybody know of a way to delete/hide this annotation from dashboard elements, or if it can be moved/adjusted so that it doesn't cover the actual block?

Many thanks!

Double click on the Lamp to open Block Parameter Window.
At the bottom of Window make "Label" = Hide in dropdown option.

duaa - not quite sure what the error message is but I suspect it has to do with your second condition in

while(k1 || (K1 == 0))

Please note how you are using a capital K instead of a lower case k. The conditions should be

while k1 || (k1 == 0)

MATLAB: Lamp VS Guage – App Designer

Finally, with the help of the Speedgoat Support, I can change the color of the lamp depending on the signal (for V2020b) directly, without the need for a Guage as intermidiate step.

My solution lines:

app.hInst  = slrealtime.Instrument(app.mdl);                      
app.hInst.connectScalar(app.OnTargetLamp,[app.mdl '/RIG_Control'],1, 'PropertyName', 'Color', 'Callback', @app.Lampper);
            
function color=Lampper (~,~,d)
    if d
        color=[0,1,0]; % If value == 1, color is green.
    else
        color=[1,0,0]; % If value == 0 or not defined, color is red.
    end
end

As I store the Instrumentation object on the App variables, the syntax can be slightly different than normal, but I also but the generic syntax below for future reference:

app.hInst  = slrealtime.Instrument('Simulink Model');                      
app.hInst.connectScalar('-GUI Lamp','-Block Path','-IO number', 'PropertyName', 'Color', 'Callback', @'app.-fcnName');
            
function '-dummy out variable'= '-fcnName'(app,time,signal)
    'algorithm to deal with the signal'
end

If you want to change more than one item, but all with the same effect. You can scale the connectScalar line to the different App Items.

If you want to have different behaviours for the same signal. Maybe use the addSignal + connectCallBack method.
