Problem with Plotting Multiple Graphs on One Handle in GUIDE

Hello,

I am trying to plot multiple graphs on one handle (axes1) with a push of a Button. Below is the code that I tried (under pushbutton1_Callback).

I tried "hold on" before and it did not work too. It says there is an error "with uicontrol Callback"

Could it be that I am implementing the hold function wrongly?

k = [1 2 3 4 5];

l = [34 66 77 22 44];

j = [3 4 7 8];

i = [99 75 41];

plot(handles.axes1,k,l)

hold(handles.axes1,'on')

plot(handles.axes1,j,i)

Thank you so much in advance!
