how can I change the current axes in a GUI?
显示 更早的评论
Hi, how can I change the current axes in a GUI? I try to use the line function, but I don’t know how to activate the right axes for plotting in the wanted figure. I guess, there should be a simple solution, but I can’t find.
Greetings

Here's one example:
axes(handles.axes2); %set the current axes to axes2
axes(h) makes existing axes h the current axes and brings the figure containing it into focus. It also makes h the first axes listed in the figure's Children property and sets the figure's CurrentAxes property to h. The current axes is the target for functions that draw image, line, patch, rectangle, surface, and text graphics objects.

Better yet would be to use
line(handles.axes2, ....)
without needing to activate the axes at all.

There is no such syntax
line(handles.axes2, ....)
This is the problem.

I'm trying to solve a nearly identical problem. However, what I'm seeing is that Matlab (2012b) seems to "forget" the current axes specification whenever that axes is in a GUIDE figure. Therefore, the following:
axes(handles.axes1)
plot([0 1],[0 1])
does not result in a line from (0,0) to to (1,1) in axes1 of the GUIDE figure, but rather it creates a new figure and plots the line in that new figure. Its strange, because the axes(handles.axes1) definitely sets the focus to the GUIDE figure first, so that part is working, but as soon as I try try to execute any command that applies to the current axes (e.g. plot, or even just "gca"), it creates a new figure and axes, i.e.:
> handles.axes1
ans = 215.0176
> axes(handles.axes1)
> gca
ans = 285.0266
with a new figure (with handle 285.0266) created.

Actually I just solved my issue... In the GUIDE layout figure window, one needs to select "Tools --> GUI Options --> Command-line accessibility" and change it to "On". The default setting was "Callback", and although the behavior I was getting was occurring inside callbacks, it didn't seem to work. Now it does.

Thanks Paulo, that worked great! Have been trying for a couple of days to solve that

Thanks Peters, the setting in GUIDE were my issue

Hi! My problem is that when I try to plot an animatedline into axis1, instead of plotting there, another window is opened. also, when I try to use axes(handles.axes1) it says:
ans =
handle to deleted Axes
Mi code is here:
function Medir_Callback(hObject, eventdata, handles)
s = abrir_puerto();
handles.x=1:20;
handles.h=animatedline('Marker','o','LineWidth',1,'Color','k');
for i=1:(length(handles.x))
handles.distancia(i)=fscanf(s,'%d');
addpoints(handles.h,i,handles.distancia(i));
drawnow;
end
cerrrar_puerto(s);
I want it to be plotted in my Matlab GUI.
Thanks, Itziar

You should start a new question rather than post this as an answer.
You aren't specifying any axes though.
doc animatedline
In common with most plotting functions this includes a syntax that allows you to specify the axes handle as the first argument. Use it!

oh, sorry i didn't notice, i'm new in this kind of matters.
The probelm is that if i specify axes in animatedlines like this it comes to the error below.
handles.h=animatedline('Marker','o','LineWidth',1,'Color','k','Parent', handles.axes1);
Error using animatedline While setting property 'Parent' of class 'AnimatedLine': Cannot set property to a deleted object

You can see this example : x = 1000*rand(40,1); y = rand(40,1); scatter(x,y) xtickangle(45) ytickangle(90)
