Gui Guide axes update limits
显示 更早的评论
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)])

Septimus - what is cols_of_data? I suspect that is a source of an error. Also what is b? You could try just
xlim(handles.axes1, [x(1) x(end)])
assuming that x(end) is the maximum element in the array.

You also shouldn't need the global variables.

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.
