Hi all; I have to plot two functions in same axes these functions in two different pushbutton functions, the code so far is as follow:
- function pushbutton1_Callback(hObject, eventdata, handles)
x = [31 32 32 33 34 35 35 37 37]; % data 1
y = [0 3 11 29 53 80 98 126 150]; % maximum power
plot(handles.axes,x,y)
- function pushbutton2_Callback(hObject, eventdata, handles)
x = [31 32 32 33 34 35 35 37 37]; % data 1
y1=y*0.7; % actual power
plot(handles.axes,x,y1)
the problem that i am facing is when plotting the second function the first is disappear. how to overcome this issue ?? please help and advice.

by using (handles.axes) so need to hold on this axes, if using hold on only its not working it will work only with plot(x,y) not with plot(handles.axes,x,y) the code should be as follow:
- function pushbutton1_Callback(hObject, eventdata, handles)
x = [31 32 32 33 34 35 35 37 37]; % data 1
y = [0 3 11 29 53 80 98 126 150]; % maximum power
plot(handles.axes,x,y)
- function pushbutton2_Callback(hObject, eventdata, handles)
x = [31 32 32 33 34 35 35 37 37]; % data 1
y1=y*0.7; % actual power
hold(handles.axes,'on')
plot(handles.axes,x,y1)

to find the problem, it's usefull to read the full code, at least of functions that are involved. Because there is no problem with
hold on;
plot(handles.axes,x,y1)
I did it and it works
