Hi, I have a GUI in Matlab and several functions in it. One function is for plotting a figure, I need to assign it to an existing axes in GUI. I have tried several options, nothing has worked out yet.

Code below is the current option I had tried before I asked here.

 set('CurrentAxes','axes11')
 plot(VyQRS(:,2));
 grid on

The plot of VyQRS I need to assign to axes11. Could you please give me any hint?

Try this:

axes(handles.axes11); % Switch current axes to axes11.
plot(VyQRS(:,2)); % Will plot into axes11.
grid on

To fix you need to pass handles into your custom pushbutton function:

function MyCustomPushButtonFunction(handles)
VyQRS=[[0:length(VyQRS)-1]' VyQRS];
axes(handles.axes11);
plot(VyQRS(:,2));
grid on
Vy_QRS=ginput; 
y_pointsQRS=VyQRS(Vy_QRS(1,1)<=VyQRS(:,1) &  Vy_QRS(2,1)>=VyQRS(:,1),:);
if size(y_pointsQRS,1)<m
    m=2;
end

Then, in a callback function, which automatically has access to handles, or some other function that has access to handles, you must call your custom function and pass handles to it:

MyCustomPushButtonFunction(handles); % Call your custom function.
