This line below should throw an error (r2019b).

get(colorbar,'enable','off')

Error using matlab.graphics.illustration.ColorBar/get
Too many input arguments. 

The get() command only has one input, the handle.

Instead, you want to check that the 'Enable' property of the colobar is set to 'off':

function colorbar_Callback(hObject, eventdata, handles)
axes(handles.axes1)
if strcmpi(get(colorbar,'enable'),'off')
    set(colorbar,'visible','on')
else
    set(colorbar,'visible','off')
end

Lastly, avoid using 'colorbar' as a variable name since it will override the function call colorbar().
