Hello all, I need to read serial data continuously and display it on Matlab GUI. I want to build a simple GUI to display water level in tank. I need to know which things of the .m file need to be updated because I am new to Matlab and its GUI environment. Please help...
Thanks in advance

A is the maximum level of water. B is the minimum. i only need to display when the tank is max or min.
thanks again

You probably should not be doing the delete(handles.figure1) . You probably should not be using a second figure at all. The figure you show for gui_cuba.fig should be enough.
ax = axes(handles.axes1);
if ~isfield(handles, 'levelplot') || ~isvalid(handles.levelplot)
handles.levelplot = animatedline('Parent', ax);
title(ax, 'Water Level');
xlabel(ax, 'time (s)')
ylabel(ax, 'depth (furlongs)')
guidata(hObject, handles)
end
current_depth = appropriate value from parameter or from arduino
current_time = appropriate value from parameter or from arduino
addpoints(handles.levelplot, current_time, current_depth);
