how refresh chart in the function?

hi, i use function to draw in app designer

app (paramter of bubu function) is a reference's graph

i use in the function "close all" and "refres variable" but if i call bubu function for second time i see the old line plotted

function bubu(app)

close all;

clearvars -except app

for i:1:1000

plot(app...,)

end

end

Use cla() to clear the axes:

function bubu(app)

      cla(app.simulaz_UIAxes_Eq,'reset')

      for i = 1:1000
          plot(app...,)
      end

end

Use refresh() function to get your plot refreshed - See DOC

[pipor]

refresh(app.simulaz_UIAxes_Eq)

Error using refresh
Handle does not refer to a figure object

Error in bubu (line 222)
refresh(app.simulaz_UIAxes_Eq)

Error in Predator_Equity/CalcolaButtonPushed (line 435)
            bubu(app);

Error in matlab.apps.AppBase>@(source,event)executeCallback(ams,app,callback,requiresEventData,event) (line 62)
            newCallback = @(source, event)executeCallback(ams, ...

How to use refresh():

H=figure;
plot(t, y);
refresh(H)

i try with 2 version:

for i=1:r
    col=rand(3,1,1)';  
    hp1=plot(Ax_Eq,XDates,TEE1(i,:),'DisplayName','OneContract','Color',col);
    refresh(hp1)
    text(Ax_Eq,c,TEE1(i,end)," xx",'Color',col);
end    

and

for i=1:r
    col=rand(3,1,1)';  
    hp1=plot(Ax_Eq,XDates,TEE1(i,:),'DisplayName','OneContract','Color',col);
    refresh(app.simulaz_UIAxes_Eq)
    text(Ax_Eq,c,TEE1(i,end)," xx",'Color',col);
end    

the same error
