MATLAB: How to prevent MATLAB from creating axes on the GUIs

When a GUI that I created is the current figure, any plot commands add an axes to that GUI.

plot(1:10)

To fix this problem, change the "HandleVisibility" property of your GUI figure to 'Off' or 'Callback'. Setting this property to 'Off' will keep any functions or commands from modifying the GUI. If you change this property to 'Callback', only callbacks of objects in the figure will be able to add plots.

To change this property in GUIDE (R12 and later) select Tools->Application Options. Then, change the Command Line Accessibility to 'Off'.

The HandleVisibility property of the figure window (for the GUI) and the axes is set to Callback by default. Thus, these handles will only be visible in a callback routine.

When you click the button and start the timer object, the first call to the TimerFcn will be within the callback and hence the axes in the GUI will be visible to it. The TimerFcn can plot into the axes in the GUI. However, subsequent plots from the TimerFcn are not from a callback. Hence, a new figure window is generated instead of plotting into the same axes in the GUI.

As a workaround, to be able to plot into the same axes, set the HandleVisibility property for the GUI (which can be obtained by double clicking anywhere on the GUIDE window except for a UIControl object) and for the axes to ON.

MATLAB: Passing values between guis

I assume your main gui is called maingui? If so, then this line:

mainguiFigureHandle  = maingui;

is what is creating another maingui. I would get rid of this line and alter the next to:

mainData = guidata(gcbf);

I also assume that somewhere along the way you have stored the handle to the subgui textbox in the handles structure as primetxt2...
