How to plot 2 graphs using the 2 axes and 2 push buttons? I have created 2 axes and 2 push buttons namely as below:
axes1
axes2
pushbutton1
pushbutton2
In the pushbutton1 property I have inserted the "Callback" column with
>>plot(simout.time,simout.signals.values)
from my simulink.
In the pushbutton2, I did the same thing to the "Callback" as
>>plot(simout1.time,simout.signals.values)
from my simulink.
The "keypressFcn" in pushbutton1 and pushbutton2 are referred to axes1 and axes2 respectively. However, the result only shown in axes1 when I press those 2 buttons. What is the problem?

You can select what's the current axes like this
axes(h) %h is the handle for the axes, for example h=handles.axes1
%your code goes here, any graphic function will appear on axes1

Where should I put the code?
I just want to create a GUI with 1 pushbutton to plot in a figure and another pushbutton to plot in another figure.
In the pushbutton1 properties, I used
>>plot(simout.time,simout.signals.values)
in the Callback and
>>axes1
in the KeyPressFcn.
In the pushbutton2 properties, I used
>>plot(simout1.time,simout1.signals.values)
in the Callback and
>>axes2
in the KeyPressFcn.
This turns out to be 2 pushbuttons plot in the same figure (axes1) only. While axes2 has nothing.

axes(axes1);plot(simout.time,simout.signals.values)

Try directing the plot to the axes handle.
For instance...
>> ah1 = subplot(2,1,1);
>> ah2 = subplot(2,1,2);
>> plot(ah1,1:10)

Hi Jarrod,
Thanks for the answer.
But the problem is I have 2 push buttons and 2 axes and I tagged each push button to each axes but in the end it turned out to be only 1 graph.
I clicked pushbutton1 the result is shown in axes1 and when I clicked pushbutton2 the result is still shown in axes1. When I click pushbutton2, it should be in axes2.
Do you know where is the problem?

It sounds like you are using GUIDE. GUIDE callbacks all have a third input argument that is a structure of handles.
So, if you are using GUIDE, you should be able to write something like...
>> plot(handles.axes1,x,y)

However, I still get an error running this GUIDE.
??? Undefined variable "handles" or class "handles.axes1".
??? Error using ==> struct2handle
Error while evaluating uicontrol CreateFcn
Please advise.

@Jarrod Rivituso Your answer helped me thanks a lot. I have a quick question please. When I use subplot and push bottom, the plots are stretched and cover all other bottoms.Would you please give me advice!Thanks
