Hi I have a Gui I created using Guide.
How would I dynamically update the axes limits using a timer?
I have data being read in and displayed. The x axes limits need be set each time the data is updated when the timer calls the update
function GUIUpdate(obj,event,handles)
global x y1
handles.plot = plot(handles.axes1,x,y1);
% What I have tried...
ax = get(handles.plot,'Parent')
b.xlim([x(1) x(cols_of_data)])
axes(handles.axes1);
xlim([x(1) x(cols_of_data)])

Global variables are almost always a bad idea. If you are absolutely certain you need them (you probably don't), then their names are way too short. You should be giving them very long names that include the function name. That way the chances of some other function using the same name for their global function are minimized.
