How to save fvtool diagram as a matlab figure??

Hi guys,

I am new with this staff and have a problem about saving fvtool Magnitude Response plot as matlab figure.

You can export it as image formats(.jpeg, .png,.. ) but not in ".fig"

Anyone can help me?

Here is simple fvtool code;

   filter_4_t =[0.2018    0.1189    0.1793    0.1793    0.1189    0.2018];
   filter_5_t =[0.1716    0.1300    0.1984    0.1984    0.1300    0.1716];
   filter_4_c =[0.2260    0.0772    0.1968    0.1968    0.0772    0.2260];
   filter_5_c =[0.1921    0.0960    0.2119    0.2119    0.0960    0.1921];
   bode=fvtool(filter_4_t,1,filter_5_t,1,filter_4_c,1,filter_5_c,1,'Fs',50);
   legend(bode,'Taylor4','Taylor5','Chebyshev4','Chebyshev5');

I want to save the bode diagram as a figure.

Is there any way to do it?

I found an answer for my problem. it is abit long way but works for me.

I get the axis data of the figure object and redraw it as a matlab figure.

   hfvt = fvtool(filterobj);
   s = get(hfvt);
   hchildren = s.Children;
   haxes = hchildren(strcmpi(get(hchildren,'type'),'axes'));
   hline = get(haxes,'children');
   x = get(hline,'XData');
   y = get(hline,'YData');

after this i can "plot (x,y)" and do whatever i can.
