Can't plot multiple figures in one axes in app designer

Hi I now struggling in how to plot multiple figures in one axes, below is my code:

 function PlotButtonPushed(app, event)
     for j = 1:(10)  
         plot(app.UIAxes,app.RESULTS.profiles_hw(:,j),(app.FE_data.Z),'LineWidth',1)
         hold(app.UIAxes,on)
     end
 end

in which, 'RESULTS' is a matrix contains 10 arraies.

How can I achieve this? My version is Matlab R2019a

Thank you very much!

When you push the plot button, what error message are you getting? I suspect it says "Undefined function or variable 'on'."

Try changing your hold command to this:

hold(app.UIAxes,'on')
