Change one specified axes to current axes when two axes exists

Just as the following image shows, two axes exists in the figure, whose tag are axes_query and axes_output , respectively. I want to implement these functions:

1) click the Button  open to display only one image on the axes_query.
2) click another button(not shown in the image, named Query) to display several images on the axes_output.

The first step is to set axes_query current axes when the Open is clicked. And then, when button Query is clicked, set axes_ouput current axes.I use the code :

 % set axes_query current axes
 axes_qh = findobj('Tag','axes_query');
 set(fig_main, 'CurrentAxes', axes_qh); % fig_main are the handle of figure.
 ...
 % set axes_output current axes
 axes_op = findobj('Tag','axes_output');
 set(fig_main, 'CurrentAxes', axes_op);

These code works well when the Query button is clicked firstly.As the following image shows,

But when I clicked Button Query again, the result is wrong, as the following image.

The current axes is axes_query,not axes_output. I am confused about this issue. When the button Open is clicked, I set axes_query current axes. And when thw button Query is clicked, I set axes_output current axes. BUT,I have no idea why the current axes is not axes_output when the Query is repeated clicked.

Any one give me some suggestion?

The best way to fix this is to not use a current axes. Instead, for each operation, name the axes it is to happen on. See http://www.mathworks.co.uk/matlabcentral/answers/22208-show-figure
